General Information[edit | edit source]
Release Notes[edit | edit source]
DAVE Embedded Systems adds to the latest Linux BSP from Renesas the customization required to support the SOC platform. For this reason most of the documentation provided by Renesas remains valid for the DESK development kit.
However, some customization is required, in particular at bootloader and linux kernel levels.
The following table reports the DESK-RZ-L releases information.

DESK-RZ-L 1.0.0[edit | edit source]
 New MVM must be installed for using DESK-RZ-L-1.0.0. The VM is available for download on DAVE's Reserved Area for registered users. |
Release notes:
- Major change to Renesas BSP 5.10.145-cip
- Carrier board support for full Linux peripherals support
Known Limitations[edit | edit source]
The following table reports the known limitations of this DESK-RZ-L release:
| Issue | Description |
|---|---|
| PCIe | If no device is connected at boot, there will be a delay while the PCIe block attempts to communicate with a device until a timeout occurs (~60 sec). |
| Ethernet | In U-Boot, the reset of the ETH_A interface via the I2C GPIO expander is not supported.
|
| Boot issue | A reboot may lead to boot issues; it is recommended to power-cycle the carrier board using the on-board power switch (turn it off and then on again). |
| Console connection | The first connection of the serial console must be performed with the board powered on; otherwise, the FTDI power cycle may be incorrect. Once the USB console is connected, the board can be powered off and on again without issues. |
| Console USB connection | The FTDI device used for the serial console may cause issues, particularly when sending binaries with the Flash Programmer. Make sure it is connected directly to the host PC and not through a USB hub.
|
| kernel | Linux kernel xconfig, make xconfig does not work
|
| Wayland backend | Yocto with Wayland backend is not supported yet |
Downloadable binary images[edit | edit source]
All binary images for DESK-RZ-L are hosted on DAVE Embedded System mirror server. There, you can find a subdirectory for each version of this development kit.
U-boot performs a 2-stage bootloader providing two files: BL2 file and FIP.
There are different BL2 images depending on the selected boot peripheral, while the FIP image is always the same.
For details on how to program the different memories, refer to the deployment section.
A summary of the available images, together with a brief description, is provided in the table below:

Release types[edit | edit source]
DESK release type can be:
- Major, when substantial changes are applied to the BSP (eg: major kernel version upgrades) or to the development kit (eg: new features, build system updates, ..). This usually means that a new DVDK is created for the DESK release
- Maintenance, when minor updates and bug fixes are introduced. This usually means that the DVDK remains the same provided with the previous major version, and only an update of the source tree repositories (and the tftp binaries) is required
As an example, DESK-RZ-L-1.1.0 is a maintenance release, so it provides the DVDK released with the 1.0.0 major release; customers can easily upgrade to the 1.1.0 release by updating the software components as described in Synchronizing git repositories.
Supported platforms[edit | edit source]
The following table reports the supported platforms in this DESK release:
| Platform | Description |

ConfigID and UniqueID[edit | edit source]
ConfigID[edit | edit source]
ConfigID is a new feature of DAVE Embedded Systems products. Its main purpose is providing an automatic mechanism for the identification of the product model and configuration.
With ConfigID, we aim at:
- completing the hardware configuration information that the software can't normally auto-detect (i.e. RAM chip version,...), implementing a dedicated reliable detect procedure
- when required, overriding the auto-detected hardware configuration information
When implemented, this mechanism allows for:
- initializing in the proper way the hardware platform, based on the specific features and parameters of the product, using a common software base (eg: a typical case is the SDRAM controller parameters, which must be configured by U-Boot depending on the particular memory chip, which can be different for the various SOM models)
- getting the complete hardware configuration (combining ConfigID with the information collectable at runtime) of a product deployed on the field
In simple words, model identification means the capability of reading a numerical code, stored in an available device (SOC's OTP , I2C EEPROM, 1-wire memories, protected NOR flash, etc.)
There are two ConfigIDs:
- SOM ConfigID: which reflects the characteristics of the SOM (stored on the SOM itself)
- Carrier Board (CB) ConfigID: which reflects the characteristics of the carrier board that hosts the SOM (stored on the carrier board itself and read by the SOM at boot time)
UniqueID[edit | edit source]
An additional attribute is UniqueID, which is a read-only code which univocally identifies a single product and is used for traceability.
|
It is worth remembering that ConfigID and UniqueID are independent from product serial number. |
Customer's action[edit | edit source]
DAVE Embedded Systems recommends to be up-to-date with Official SOM's BSPs for taking advantages of ConfigID/UniqueId features: this is the only required action.
- ConfigID advantage: to allow U-Boot bootloader to be executed only with the correct configuration (if the U-Boot loaded is not the proper one, it may stop execution avoiding incorrect behaviour)
- UniqueID advantage: to trace univocally each individual SOMs and, in turn, all the on-the-field equipments
ConfigID values[edit | edit source]
ConfigID is a N-bit (typically N>8) signed integer, that can have the following values:
- < 0: error
- -1: not initialized
- = 0: ConfigID legacy
- for prototypes (ConfigID not yet defined) or for products manufactured before the introduction of the ConfigID feature
- > 0: valid ConfigID
- values are reported accordingly with the specific product table
Hardware implementations of the ConfigID[edit | edit source]
The following paragraphs briefly describe the available solutions for storing the ConfigID.
OTP on the SOC[edit | edit source]
Some SOCs provides programmable OTPs (eg. for security, MAC address, boot modes, etc). Usually, some of these are general purpose registers and can be managed by the user.
This is the ideal implementation, because:
- ConfigID is stored in the most important component of the SOM
- the component that hosts the ConfigID is NOT optional
- typically, a very selective lock can be forced. In general, for reliability and/or security reasons, OTP areas used to store ConfigIDs may be locked during the manufacturing process.
OTP 1-wire memory[edit | edit source]
This implementation requires a 1-wire memory chip.
I2C Eeprom[edit | edit source]
This implementation requires connecting an EEPROM to an I2C bus of the SOC. Moreover, routing a write protect pin to the SOM connector is required.
NOR Flash SPI[edit | edit source]
This implementation requires a NOR flash connected to the SPI bus of the SOC.
DAVE Embedded Systems' hardware implementation[edit | edit source]
DAVE's SOCs implement the ConfigID feature depending on hardware Capabilities of the SOCs. The following list shows the priority used for its implementation:
- OTPs
- example: AXEL family processor (i.MX6) implements ConfigID using processor's OTP
- AXEL uses GP1 eFuse register to store ConfigID
- NOR Flash SPI
- example: DIVA family processor (AM335x) implements ConfigID using NOR SPI (if present)
- DIVA and BORA use the first 32bytes OTP block on NOR SPI to store ConfigID (and its CRC32), UniqueID (and its CRC32)
- I2C Eeprom
- example: DIVA family processor (AM335x) or BORA Lite processor (ZYNQ) implements ConfigID using I2C Eeprom when NOR SPI is not present (module boots from NAND or SD)
- DIVA and BORA Lite use the first 32bytes on I2C EPROM to store ConfigID (and its CRC32), UniqueID (and its CRC32)
- 1-wire
- example: latest AXEL Lite, AXEL ULite and BORA/BORA Xpress/BORA Lite Evaluation Kits implement CB ConfigID using the onboard 1-wire device (DS2431)
Software implementation[edit | edit source]
U-Boot[edit | edit source]
u-boot integrates the software routines for reading and displaying the ConfigID: hereunder an example of SOM ConfigID at startup:
U-Boot 2013.04-00010-gcb05b30 (Jun 26 2015 - 12:49:26)-xelk-2.1.0 CPU: Freescale i.MX6Q rev1.5 at 792 MHz CPU: Temperature 47 C, limits (-40 C, 125 C), calibration data: 0xc0 Reset cause: POR Environment: SPI Flash I2C: ready DRAM: 2 GiB Now running in RAM - U-Boot at: 8ff35000 NAND: 512 MiB MMC: FSL_SDHC: 0, FSL_SDHC: 1 SF: Detected S25FL256S with page size 64 KiB, total 32 MiB In: serial Out: serial Err: serial Power: found PFUZE100 (devid=10, revid=21) SOM ConfigID#: 00000003 SOM UniqueID#: df646299:0b0579d4
For accessing these information on Linux procfs, the device tree must be modified (using u-boot fdt command): for example:
DIVA# setenv fdtfixup 'fdt addr ${fdtaddr}; run fdtfixup_configid'
DIVA# setenv fdtfixup_configid 'fdt set / som_configid ${som_configid#}; fdt set / som_uniqueid ${som_uniqueid#}; fdt set / cb_configid ${cb_configid#}; fdt set / cb_uniqueid ${cb_uniqueid#}'
Linux[edit | edit source]
It is possible to read the ConfigID/UniqueID via procfs; for example:
root@axel-lite:~# cat /proc/device-tree/som/configid && echo 00000003 root@axel-lite:~# cat /proc/device-tree/som/uniqueid && echo df646299:0b0579d4 root@axel-lite:~#
Legacy device tree, has a sightly different procfs structure:
root@axel-lite:~# cat /proc/device-tree/som_configid && echo 00000003 root@axel-lite:~# cat /proc/device-tree/som_uniqueid && echo df646299:0b0579d4 root@axel-lite:~#
A real case example of ConfigID benefit[edit | edit source]
The ConfigID benefit is clear when:
- there is a number of products deployed on the field
- the products deployed on the field needs a SW update
The ideal scenario is that all products are equal and there are no differences on the Bill Of Material (BOM):
- All products have the same BOM with a single Config ID
ConfigID A
ConfigID A
ConfigID A
ConfigID A
ConfigID A
ConfigID A
In this case there are no problems to deploy a new SW update on the field: all products have the same HW configuration, then the same SW configuration.
Unfortunately, this is an ideal scenario. The reality is that:
- component obsolescence
- product shortage
- second source strategies
force to have an on-the-field different version of product (with same functionalities but with different HW configuration) which doesn't permit to realize what proposed in the ideal case.
|
The usage of the ConfigID technique, allows the running SW to identify the underlying HW configuration and automatically adapt the BSP (i.e. the driver layer) to properly use the HW subsystems: this, maintaining the overall product features identical to the final User point-of-view. |
- All products are similar BUT there are different Config ID between the 2 product versions
ConfigID A
ConfigID A
ConfigID B
ConfigID B
ConfigID A
ConfigID B
With a scenario, like the one described above, if you would like to update the SW you need to implement a strategy for understanding what platform version is going to be updated. The Config ID is used exactly for this goal.
The ConfigID provides to the software update routine the information on which product version is so the update can be adapted to the exact product version.
In this way, you can distribute one single version of the software update which will automatically adapt itself to the currently running platform.
How to handle After Sales with Config ID[edit | edit source]
One of the mos common questions about Config ID is how to handle the Config ID issue. Below is described with an example how to handle it.
This product is returned from the field with a problem on the display:
After Sales Dept analizes the product and decide to substitute the display. The problem is that the existing display is not available - because of is End Of Life (EOL) - and it is required to move to a different display: in the product a different Config ID will be written because of the 2 displays requires a dedicated SW version and cannot be distinguished automatically during the startup. The final result is to have the similar product:
As indicated, the new display requires a different Config ID (from A to B) so it can be updated with an easy software routine before start the SW update. This Config ID update routine can be implemented in manufacturing facility typically using a dedicated USB pen drive which modify the saved ConfigID to the new one depending on the storage memory in use
ConfigID[edit | edit source]
This article describes how the ConfigID is implemented in the products supported by the DESK-RZ-L Linux Kit.
ZERO[edit | edit source]
As ZERO is a system-on-module (SOM), the typical mechanism described here is used.
System and ConfigID Overview[edit | edit source]
A system is defined by the combination of a System on Module (SOM) and a carrier board. To uniquely identify the actual hardware configuration, two distinct ConfigIDs are used, effectively describing the SOM + carrier board pair as a single system.
For clarity, the two identifiers are named as follows:
- SOM ConfigID: identifies the SOM configuration
- CB ConfigID: identifies the carrier board configuration
Example from the U-Boot boot log[edit | edit source]
... SOM ConfigID#: 00000001 SOM UniqueID#: 00000000:00000000 CB ConfigID#: 00002003 CB UniqueID#: f2000041:21226b2d ...
Meaning of the ConfigIDs[edit | edit source]
In general:
- SOM ConfigID Identifies the SOM variant and its base hardware features, including possible hardware revisions.
- CB ConfigID Identifies the carrier board, defining the available peripherals and I/O interfaces.
ConfigIDs in U-Boot[edit | edit source]
During the U-Boot boot process, the following lines are particularly relevant:
SOM ConfigID#:for example00000001CB ConfigID#:for example00002002
The SOM ConfigID is used to select the correct SOM-specific configuration.
The CB ConfigID is used to select the correct carrier-board-specific configuration, ensuring that the proper peripherals, pin multiplexing, and interfaces are enabled.
This separation allows the same SOM to be safely and correctly used with different carrier boards while preventing incorrect hardware initialization.
ConfigID & BOM Mapping[edit | edit source]
Identifying the SOM and Carrier Board and Their Capabilities[edit | edit source]
The BOM code is printed on the physical label of the board under consideration.
This code, together with the ConfigID, allows unambiguous identification of the System on Module (SOM), the Carrier Board, and the set of hardware features that are available.
SOM ConfigID[edit | edit source]
The following table shows the relationship between the SOM ConfigID, the corresponding BOM, and the SOM description.
| ConfigID | BOM | Description |
|---|---|---|
| 0x00000001 | DSABA30000I1R | SOM spin 1 |
Carrier Board (CB) ConfigID[edit | edit source]
The table below lists the supported Carrier Board configurations, identified by CB ConfigID and BOM.
| ConfigID | BOM | Description |
|---|---|---|
| 2000 | EB23000xI1R | Generic OSM SoM carrier board |
| 2001 | EB23010xI1R | Routing for ZERO SoM – 9-axis motor demo |
| 2002 | EB23020xI1R | Routing for ZERO SoM – full Linux support, no motor interface |
| 2003 | EB23030xI1R | Routing for ZERO SoM – 6 motors only, remaining pins available for Linux peripherals |
This mapping enables the bootloader and the operating system to automatically select the correct hardware configuration, preventing incorrect peripheral initialization and reducing the risk of hardware damage.
Booting from NFS[edit | edit source]
This configuration is very helpful during software development (both for kernel and applications).
The kernel image is downloaded via TFTP while the root file system is remotely mounted via NFS from the host. It is assumed that the development host:
- is connected with the target host board through an Ethernet LAN
- exports the directory containing the root file system for the target through the NFS server
- runs a TFTP server.
- has a proper subnet IP address
net_nfs configuration[edit | edit source]
The Virtual Machine is properly configured for the TFTP and NFS debug.
In any case, some variables have to be configured on the target, and the VM itself has to be configured with respect to the network environment.
Host (Virtual Machine) configuration[edit | edit source]
The Virtual Machine has the tftp and nfs services already running.
Optionally, their configuration has to be changed according to the network configuration to which the target is connected.
Check and properly configure the items described in VirtualBox Network Configuration
Target configuration[edit | edit source]
The IP address for the server and target should be configured: an example (for a network subnet 192.168.0.x)
u-boot=> setenv serverip 192.168.0.89 u-boot=> setenv ipaddr 192.168.0.169 u-boot=> setenv gatewayip 192.168.0.254 u-boot=> setenv netmask 255.255.255.0 u-boot=> setenv netdev eth0
serveripis the IP address of the host machine running the tftp/nfs serveripaddris the IP address of the targetgatewayipis the gateway address of the targetnetmaskis the netmask address of the targetnetdevis the name of the Ethernet interface of the target
For using the DVDK Virtual Machine, a static IP address configuration has been selected. To the U-Boot variable ip_dyn has to be set to no:
u-boot=> setenv ip_dyn no
The kernel and device tree files have to be selected
u-boot=> setenv image boot/Image
AURA has its dtb file boot/rzt2h-eb23-cb2003.dtb or boot/rzt2h-eb23-cb2002.dtb, set the correct DTB to use, example:
u-boot=> setenv fdtfile boot/rzt2h-eb23-cb2003.dtb
Finally, the root file system directory on the Virtual Machine should be configured to let the kernel find the INIT
u-boot=> setenv rootpath /home/dvdk/desk-rz-l/rootfs
To run this configuration, just issue the net_nfs command, which firstly downloads the kernel and device tree using the tftp protocol
u-boot=> setenv net_nfs 'run tftp_loadk tftp_loadfdt nfsargs addip addcons addmisc; sleep 10; booti ${loadaddr} - ${fdtaddr}'
Below is the complete bootlog from nfs:

Synchronizing the git repository[edit | edit source]
In DESK-RZ-L, the following source trees are clones of the correspondent DAVE Embedded Systems git repositories:
| Component | GIT Remote |
|---|---|
| Flash Programmer | https://git.dave.eu/git/desk-rz-l/flash-programmer.git
|
| TF-A | https://git.dave.eu/git/desk-rz-l/trusted-firmware-a.git
|
| U-Boot | https://git.dave.eu/git/desk-rz-l/renesas-u-boot-cip.git
|
| Linux kernel | https://git.dave.eu/git/desk-rz-l/rz-linux-cip.git
|
| Yocto BSP | https://git.dave.eu/git/desk-rz-l/meta-desk-rz.git
|
For more information about the access to these repositories, please refer to this link.
Instructions[edit | edit source]
The components listed in the table above can be kept in sync and up to date with DAVE Embedded Systems' repositories.
Once the git account has been enabled, the developer can:
- clone the repository with the
git clone <git_remote_repository>command - synchronize a source tree entering the repository directory and launching the
git fetch origincommand.
Please note that git fetch doesn't merge the commits on the current branch. To do that, the developer should run the git merge command or replace the fetch-merge process with a single git pull command. Please note that the recommended method is the fetch-merge process. For further information on Git, please refer to the official Git Documentation

Instructions[edit | edit source]
To build the BL2 and FIP boot binaries, you must first build U-Boot. Refer to Building U-Boot with make.
Once the U-Boot binaries are available, copy the u-boot.bin file into the Trusted Firmware-A (TF-A) project directory.
The build process requires multiple steps; it is not a single command. A helper script is provided in the project to simplify the build: build.sh.
Example of building:
dvdk@vagrant:~/desk-rz-l/trusted-firmware-a$ source ~/desk-rz-l/desk-rz-l-1.0.0_env.sh dvdk@vagrant:~/desk-rz-l/trusted-firmware-a$ ./build.sh REALCLEAN CC bl2/aarch64/bl2_arch_setup.c CC

NOTE: This is the default configuration suitable for the latest target.
- The former command selects the default DESK-RZ-L configuration, while the latter builds the kernel binary image with the required U-Boot header and the kernel device tree.
Default Linux kernel configuration can be changed by using the standard menuconfig, xconfig, or gconfig make target. Subsequent builds just require Image make target to update the binary image. Once the build process is complete, the kernel binary image is stored in the arch/arm/boot/Image file. Both this file and the kernel device tree can be copied to the tftp root directory /tftpboot/boot/ with the following commands:
dvdk@vagrant:~/desk-rz-l/rz-linux-cip$ cp arch/arm64/boot/Image /tftpboot/boot/ dvdk@vagrant:~/desk-rz-l/rz-linux-cip$ cp arch/arm64/boot/dts/renesas/*.dtb /tftpboot/boot/
Usually, kernel modules are installed with the make modules_install command, but this method installs the modules into the /lib/modules directory of your MVM, which is not what you want.
A better way to deploy kernel modules while cross-compiling is
- generate a
.tar.gzarchive - install this archive into the target root file system
The user can create such an archive, for example, using the following commands:
dvdk@vagrant:~/desk-rz-l/rz-linux-cip$ mkdir modules-install dvdk@vagrant:~/desk-rz-l/rz-linux-cip$ make INSTALL_MOD_PATH=modules-install modules_install dvdk@vagrant:~/desk-rz-l/rz-linux-cip$ cd modules-install dvdk@vagrant:~/desk-rz-l/rz-linux-cip/modules-install$ tar cvzf ../modules.tar.gz . && cd .. dvdk@vagrant:~/desk-rz-l/rz-linux-cip$
Now copy modules.tar.gz into the target root file system and install them as root with the following command
root@desk-t2h-usd-devel:~# tar xvzf modules.tar.gz -C /

Introduction[edit | edit source]
As is known, in addition to a bootloader and the OS. An embedded Linux system, such as a kernel, requires a root file system to operate. The root file system must contain everything needed to support the Linux system (applications, settings, data, etc.). The root file system is the file system that is contained on the same partition on which the root directory is located. The Linux kernel, at the end of its startup stage, mounts the root file system on the configured root device and finally launches the /sbin/init, the first user space process and "father" of all the other processes.
For more information on the Linux filesystem, please refer to http://www.thegeekstuff.com/2010/09/linux-file-system-structure/.
DESK-RZ-L provides one (or more) pre-built root file system, that can be used during the evaluation/development/deployment cycle. For instance, the root file system included in the desk-rz-l-1.x.x-image-devel image is suited for the development phase, since it provides a relatively rich set of packages including tools and libraries used to debug the application code. The pre-built root file systems are located here: /home/dvdk/<target_name>/rootfs/.
To generate the supported root file systems, the build of the Yocto BSP has to be run. The output of this process is an image containing the U-Boot binary file, the Linux kernel image, and the selected root file system image. The following sections describe in detail how to execute this operation.
For more general information regarding the Yocto build system, please refer the dedicated category page.
How to build the Yocto BSP images including the U-Boot binary file, the Linux kernel image, and the target root file system image with KAS[edit | edit source]
|
The following procedure requires access to the DAVE Embedded Systems' git repositories. Access to such repositories is granted to the development kit's owners only. Please refer to this page for detailed instructions on how to get it. |
|
This process requires a lot of hardware resources in terms of disk storage, RAM, and processing power. For this reason, it is also recommended to consider the use of a physical machine. |
Initialize the build environment[edit | edit source]
Check that the following packages are installed:
dvdk@vagrant:~$ sudo apt-get update && sudo apt install bc bmap-tools cpio curl debianutils gawk gcc git git-core iperf3 iputils-ping libc6-dev-i386 libncurses5-dev libyaml-dev libtinfo5 lintian mesa-common-dev p7zip-full picocom python python3 python3-jinja2 python3-pexpect python3-pip python3-subunit pylint3 sudo u-boot-tools unzip vim virtualenv wget xz-utils chrpath texinfo diffstat zstd gcc-multilib libegl1-mesa libgmp-dev libmpc-dev libsdl1.2-dev pylint python3-git socat xterm libpulse-dev gdb libssl-dev libelf-dev libncurses-dev build-essential lzop python-yaml gparted syslinux pxelinux net-tools
Before running the build, the KAS environment must be initialized properly.

Running the build[edit | edit source]
Please note that even the basic root file system requires a few hours to build on a mid/hi range desktop (4-6 cores, 8-12 GiB RAM) also depending on your Internet connection speed (all sources are fetched from the network). Nearly 200GiB of disk space is required for the build; this means that an external VDI disk should be created and mounted for a complete Yocto build. The process may be slowed down significantly since the performances of a virtual machine are reduced if compared to the physical hardware. Thus, it's recommended to check the hardware capabilities of the host system and, when building with Yocto is required, to consider the following options:
- Migrating the build system to a physical machine
- Assuming that the host system has the required resources, extending the hardware capabilities of the default MVM (e.g. adding more cores and disk space).
Once completed the initialization phase, developers can launch the Yocto image build with KAS, with the following commands:
- for build
dave-image-develimage withDESK-RZ-Lmachine
(venv) dvdk@vagrant:~/desk-rz-l/meta-desk-rz$ kas build desk-rz-l_devel.yml
Once the build process is completed, the resulting files (the U-Boot binaries, the Linux kernel image, the device tree blob, the .tar.gz compressed root file system image, etc.) will be available in build/tmp/deploy/images/<machine_name>.
Generating the SDKs[edit | edit source]
In order to get the corresponding SDK, perform the following command:
- for
DESK-RZ-Lmachine
(venv) dvdk@vagrant:~/desk-rz-l/meta-desk-rz$ KAS_TASK="populate_sdk" kas build desk-rz-l_devel.yml
Generating the Toolchain[edit | edit source]
The toolchain can be created by the following command:
- for
DESK-RZ-Lmachine
(venv) dvdk@vagrant:~/desk-rz-l/meta-desk-rz$ KAS_TARGET="meta-toolchain" kas build desk-rz-l_devel.yml
Building additional packages[edit | edit source]
To build additional packages, for example memtester, the user needs to perform the following command
(venv) dvdk@vagrant:~/desk-rz-l/meta-desk-rz$ KAS_TARGET="memtester" kas build desk-rz-l_devel.yml
The resulting packages (the default format is rpm) can be found inside build/tmp/deploy/rpm.
Hello word example[edit | edit source]
Below is an example on C code displaying the classic Hello World! message on the target serial console.
This example shows how to use the arm cross-compiler using the environment configured for this purpose.
Setting the cross-compiler[edit | edit source]
- start the Linux development VM and log in to the system
- open a terminal window and cd into your source code directory
dvdk@vagrant:~/desk-rz-l$ mkdir myproject
dvdk@vagrant:~/desk-rz-l$ cd myproject/
dvdk@vagrant:~/desk-rz-l/myproject$ vi hello.c
dvdk@vagrant:~/desk-rz-l/myproject$ cat hello.c
#include <stdio.h>
int main(){
printf("Hello, World!\n");
return 0;
}
- configure the build environment
dvdk@vagrant:~/myproject$ source ~/desk-rz-l/desk-rz-l-1.0.0_env.sh
- as you can see here below, the
$CCenvironment variable has been properly configured for using the SDKsysrootparameter:
dvdk@vagrant:~/desk-rz-l/myproject$ echo $CC aarch64-poky-linux-gcc -mtune=cortex-a55 -fstack-protector-strong -D_FORTIFY_SOURCE=2 -Wformat -Wformat-security -Werror=format-security --sysroot=/opt/yocto/sdk/desk-rz-l/desk-t2h-l-1.0.0/sysroots/aarch64-poky-linux dvdk@vagrant:~/desk-rz-l/myproject$
- invoke the cross-compiler for compiling your source code example: the object file obtained is a proper ELF 64-bit for the target microprocessor
dvdk@vagrant:~/desk-rz-l/myproject$ $CC hello.c -Os -o hello dvdk@vagrant:~/desk-rz-l/myproject$ file hello hello: ELF 64-bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-aarch64.so.1, BuildID[sha1]=01215e39e6f425d38c5da326d0a241795d01da5f, for GNU/Linux 3.14.0, with debug_info, not stripped dvdk@vagrant:~/desk-rz-l/myproject$
Running the example on the target[edit | edit source]
Now it is enough to copy the object file in the /home/root rfs directory and boot from nfs:

Flash programmer over SCI mode[edit | edit source]
The Flash Programmer tool is required when you want to program the NOR flash without first booting from other peripherals and then programming it from a higher software level.
It is a bare-metal tool that runs on the CR52 core, and its main purposes are:
- Initialize the minimum set of peripherals required for the following operations
- Initialize the DDR
- Use xSPI0 to program the connected NOR flash
Boot from SCI Mode[edit | edit source]
See Boot options for how to set the bootstrap pins to boot in SCI mode.
Detect SCI mode running correctly[edit | edit source]
To verify that the system has correctly booted in this mode, check that the following message appears:
SCI Download mode (Normal SCI boot)
If this message appears on the debug console, the system is running in the correct mode.
Send binary[edit | edit source]
There are two ways to send the Flash Programmer binary over the debug serial port:
- From Windows using the
Tera Termtool - From Linux
In any case, the sequence to follow is the follows:
- Power on the board in SCI download mode
- Send the Flash Programmer header
- Send the Flash Programmer
- After the transfer, a prompt will appear
- Program BL2 into the NOR:
- Run the command
XSPIW 0 0 0 - Send the BL2 srec file over the serial port
- Run the command
- Program U-Boot:
- Run the command
XSPIW 0 0x60000 0 - Send the FIP srec file over the serial port
- Run the command
Attention: sending the binaries is slow; the process takes several minutes.
The files can be found either on the MVM or on the DESK-RZ-L-1.0.0 mirror and downloaded from there.
Note that the MVM may contain older versions; it is recommended to download the latest version from here.
From Windows[edit | edit source]
- Open the serial port using the
Tera Termtool - Open, with Windows Explorer, the directory where the downloaded binaries are located. The required binaries are:
HDR NM: Flash Programmer headerFlash_Programmer_SCIF_CR52_RZT2H_EVK.mot: Flash Programmerbl2_bp_xspi0-desk-t2h-usd-devel.srec: TF-A BL2fip-desk-t2h-usd-devel.srec: U-Boot
- Send the Flash Programmer header
HDR NM(drag theHDR NMfile from the Explorer window and drop it into theTera Termterminal)- A dialog will appear; make sure
Send File (Paste content of file)is selected and clickOK
- A dialog will appear; make sure
- If the header is sent correctly, the message
-- Load Program to RAM ---------------will appear- In the same way, send the file
Flash_Programmer_SCIF_CR52_RZT2H_EVK.mot(this may take some time)
- In the same way, send the file
- A string similar to
Flash Programmer V1.03 (RZT2H)(CR52_0) (built: Sep 10 2025, 13:34:42)will appear, followed by the prompt> - The Flash Programmer tool has now been loaded; proceed with programming the NOR flash with BL2 and FIP
- Run the command
xspiw 0 0 0 - As before, send the file
bl2_bp_xspi0-desk-t2h-usd-devel.srec - When finished, run the command
xspiw 0 0x60000 0 - As before, send the binary
fip-desk-t2h-usd-devel.srec(this may take several minutes)
- Run the command
Example:
SCI Download mode (Normal SCI boot) -- Load Program to RAM --------------- -- Start Boot Program on RAM --------- Flash Programmer V1.03 (RZT2H)(CR52_0) (built: Sep 10 2025, 13:34:42) > xspiw 0 0 0 send file Erased Written > > xspiw 0 0x60000 0 send file Erased Written >
From Linux[edit | edit source]
For example, when using the DVDK Virtual Machine, just connect the debug serial port to the MVM and use the picocom tool to verify that the serial connection is working correctly:
dvdk@vagrant:~/desk-rz-l/bin$ picocom -b 115200 /dev/ttyUSB0 picocom v3.1 port is : /dev/ttyUSB0 flowcontrol : none baudrate is : 115200 parity is : none databits are : 8 stopbits are : 1 escape is : C-a local echo is : no noinit is : no noreset is : no hangup is : no nolock is : no send_cmd is : sz -vv receive_cmd is : rz -vv -E imap is : omap is : emap is : crcrlf,delbs, logfile is : none initstring : none exit_after is : not set exit is : no Type [C-a] [C-h] to see available commands Terminal ready SCI Download mode (Normal SCI boot)
On the MVM, the directory /home/dvdk/desk-rz-l/bin/ contains the following binaries:
bl2_bp_xspi0-desk-t2h-usd-devel.srec: TF-A BL2fip-desk-t2h-usd-devel.srec: U-BootFlash_Programmer_SCIF_CR52_RZT2H_EVK.mot: Flash ProgrammerHDR NM: Flash Programmer header
Using cat or echo redirected to the debug serial port, it is possible to send the binaries. Below is an example script that programs U-Boot.
The script assumes that the board has just been powered on and that no data has been sent on the serial port before running it.
In parallel, it is possible to keep a separate terminal open to cat the serial port in order to monitor the progress and diagnose any issues.
#!/bin/bash
# send_serial.sh
# Script to send files over serial with intermediate progress messages
# Usage: ./send_serial.sh <serial_port> <HDR_NM> <Flash_Programmer.mot> <bl2.srec> <fip.srec>
if [ "$#" -ne 5 ]; then
echo "Usage: $0 <serial_port> <HDR_NM> <Flash_Programmer.mot> <bl2.srec> <fip.srec>"
exit 1

ConfigID[edit | edit source]
See ConfigID for further details.
Linux boot[edit | edit source]
The kernel is executed only if the CB ConfigID# is 2002 or 2003.
This ensures that the correct kernel and DTB are used depending on the carrier board present, in particular, preventing motor signals from being driven incorrectly if the pins are assigned to unconnected peripherals, which could cause hardware damage.
The kernel and the Root File System (RFS) must be provided via the uSD card.
From the mirror, you can download the file desk-rz-image-desk-t2h-usd-devel.wic.bz2.
Decompress it using 7-Zip (or similar tools) and program the uSD card using a tool such as Balena Etcher.
Insert the uSD card into the dedicated connector.
U-Boot will automatically look for the binaries on the uSD card and proceed to boot the Linux kernel from uSD.

Peripheral Ethernet[edit | edit source]
There are multiple Ethernet interfaces available; see RZ/T2H and RZ/N2H User’s Manual – Hardware, section 27 Ethernet Subsystem.
The device provides three GMAC instances, allowing up to three independent Ethernet interfaces. A fourth interface can be used together with the others to achieve an EtherCAT or switch configuration.
As described in the user manual, section 27.3.2, the possible configurations are:
| Mode | Interface 0 | Interface 1 | Interface 2 | Interface 3 |
|---|---|---|---|---|
| 000b | ETHSW Port 0 | ETHSW Port 1 | ETHSW Port 2 | GMAC1 |
| 001b | ESC Port 0 | ESC Port 1 | GMAC2 | GMAC1 |
| 010b | ESC Port 0 | ESC Port 1 | ETHSW Port 2 | GMAC1 |
| 011b | ESC Port 0 | ESC Port 1 | ESC Port 2 | GMAC1 |
| 100b | ETHSW Port 0 | ESC Port 1 | ESC Port 2 | GMAC1 |
| 101b | ETHSW Port 0 | ESC Port 1 | ETHSW Port 2 | GMAC1 |
| 110b | ETHSW Port 0 | ETHSW Port 1 | GMAC2 | GMAC1 |
| 111b | GMAC0 | GMAC1 | GMAC2 | — |
The default/basic setup is:
| Mode | Interface 0 | Interface 1 | Interface 2 | Interface 3 |
|---|---|---|---|---|
| 111b | GMAC0 | GMAC1 | GMAC2 | — |
The Ethernet PHYs are not present on the SoM; they must be provided on the carrier board.
The three Ethernet interfaces share the same MDIO bus. This bus is defined in the GMAC0 block; see the DTS in the following section.
The fourth Ethernet PHY is present but not used in the current configuration and is connected to a different MDIO bus.
The address/mapping is as follows:
| Interface | GMAC | MDIO Bus | Address |
|---|---|---|---|
| ETH_A | gmac0 | GMAC0 | 0 |
| ETH_B | gmac1 | GMAC0 | 1 |
| ETH_C | gmac2 | GMAC0 | 2 |
| ETH_D | — | ETHSW | 3 |
Configuration[edit | edit source]
These peripheral(s) can only be used with the following ConfigID(s) (see the associated BOM):
| ConfigID | Note |
|---|---|
| 2002 | ETH_D pins connected to the Ethernet PHY |
| 2003 | Ignore references to the ETH_D port, as the pins are used for the motors |
Device tree configuration[edit | edit source]
Below is an example of a device tree configuration used on a standard DAVE kit for the DSAB EVK.
The Ethernet PHY reset pins are controlled by a GPIO expander (exp_2) connected on the i2c_0 bus.

Accessing the peripheral[edit | edit source]
The interfaces are mapped as described in the aliases section of the DTS:
/ {
...
aliases {
...
i2c0 = &i2c0;
eth0 = &gmac0; // ETH_A
eth1 = &gmac1; // ETH_B
eth2 = &gmac2; // ETH_C
};
...
};
U-boot usage[edit | edit source]
In U-Boot, only the ETH_A port is usable.
In the DESK-RZ-L-1.0.0 release, support for the i2c_0 bus is missing; as a result, the reset pins of the Ethernet PHYs cannot be driven by software.
As a workaround, the reset can be handled manually.
As shown in the image below, it is possible to control the reset of the ETH_A Ethernet PHY by pulling pin 6 of connector J54. This is done using a short wire with a 10–12 kΩ series resistor connected to pin 2 of the same J54 connector.
This operation should be performed only when the Ethernet interface is needed.
After using Ethernet in U-Boot, it is recommended to remove the wire before booting Linux.
Leaving it connected interferes with correct Linux operation, since Linux uses the GPIO expander exp_2 to control the PHY reset.
Example: kernel Image download via TFTP
Set IP addresses:
=> setenv ipaddr 192.168.0.168 => setenv serverip 192.168.0.169
If the PHY reset is not performed, the connection will fail:
=> ping 192.168.0.169 Could not get PHY for ethernet@80100000: addr 0 phy_connect() failed FAILED: 0 Using ethernet@80100000 device ARP Retry count exceeded; starting again ping failed; host 192.168.0.169 is not alive
Perform the manual reset.
Note that if the wire was already connected at power-on, it must be removed and reinserted, since the reset timing during boot is incorrect.
=> ping 192.168.0.169 ethernet@80100000 Waiting for PHY auto negotiation to complete...... done Using ethernet@80100000 device host 192.168.0.169 is alive =>

Peripheral PCI express[edit | edit source]
The PCIe bus is available; see details in RZ/T2H and RZ/N2H User’s Manual – Hardware, section 56 PCI Express 3.0 Interface (PCIe).
The PCIe bus can be configured in the following modes:
- 1 lane with 2 channels
- 2 lanes with 1 channel each
The EVK uses the second configuration (2 lanes with 1 channel each).
Warning: If no device is connected at boot, there will be a delay while the PCIe block attempts to communicate with a device until a timeout occurs. If a device is detected during the boot, there will be no interruptions or pauses.

Note[edit | edit source]
The clock signal must be requested by the PCIe devices. If a device is not found or recognized, first check whether the clock is present. If the clock is missing, the inserted device probably does not drive the Clock Request pin. Manual intervention is possible via test points or components:
- TP140 – to handle the Clock Request for the J15 PCIe connector
- D46.1 (white dot marks pin 1) – to handle the Clock Request for the J18 M.2 connector
Peripheral SD[edit | edit source]
The 4-bit uSD card is mainly used as a kernel and Root File System (RFS) storage device.
N.B.: the Card Detect (CD) signal is not native in the SoC; a GPIO expander is used to hanlde it. The expander used is exp_0 on the i2c_0 bus.
The CD pin is used only by Linux. In U-Boot, since there is no support for the I2C bus, the CD pin is not used to detect whether a uSD card is present or not.

Accessing the peripheral[edit | edit source]
The uSD card appears as an MMC device with instance 0, as described in the aliases section of the DTS:
/ {
...
aliases {

};
...
The following example uses an 8 GB uSD card is used with 2 partitions. The second partition contains the Root File System (RFS), which includes the boot directory where the kernel and DTB binaries are located.

Peripheral I2C[edit | edit source]
Notice: On the I2C bus B, there is the PCIe clock generator and RTC, which is located in the SoM. If the EVK is used with ConfigID 2003 (I2C B pins used for motors), the PCIe blocks and RTC are not initialized; therefore, no side effects are observed when running motor demos.
Configuration[edit | edit source]
These peripheral(s) can only be used with the following ConfigID(s) (see the associated BOM):
| ConfigID | Note |
|---|---|
| 2002 | Available I2C buses are A and B; the attached devices are split across the two buses |
| 2003 | Only I2C bus A is available; all devices except the touch controller and RTC are moved from I2C B to I2C A (I2C B pins are used to drive motors) |

Accessing the peripheral[edit | edit source]
The examples shown are obtained using a board with ConfigID 2002 (both I2C buses A and B present).
Attention:
Touch devices are detected only if they are physically connected to the board.
In the following example, the touch device is not present; therefore, the device at address 0x41 is not visible on the I2C bus.
The INA226 devices are expected to be visible by default and usable from Linux at addresses 0x44 and 0x45.
Using connector J53, it is possible to disconnect these devices from the on-board I2C bus and instead use them on an external I2C bus, for example, to perform measurements during suspend or in other states where the embedded system cannot access or perform sensor readings.
Refer to the image below for the connector location and additional details.
| Pin | Description |
|---|---|
| 1 | GND |
| 2 | SCL (normally on-board I2C bus); see pin 4 (EN). If EN = GND, use an external I2C bus |
| 3 | SDA (normally on-board I2C bus); see pin 4 (EN). If EN = GND, use an external I2C bus |
| 4 | EN (normally tied to the voltage level of pin 6); pull to GND to disconnect the INA226 devices |
| 5 | NC |
| 6 | V_INA |
If pin 4 (EN) is left unchanged, the I2C bus can be routed externally.

Peripheral xSPI[edit | edit source]
There is one Expanded Serial Peripheral Interface (xSPI).
The xSPI protocol defines the interface for memory devices, offering high data throughput, a low signal count, and a limited backward compatibility with legacy SPI devices.
This bus is a boot bus: an SPI NOR flash is connected to it on the carrier board.
This bus can also be used via the bare-metal tool Flash Programmer to program the NOR memory, enabling boot from SCI.
By storing the correct binaries in the proper layout/position in the NOR, it is possible to boot through the xSPI bus.

The GPT cell gpt00_3 is dedicated to the backlight and cannot be used directly as a PWM; see the LCD display page.
The cell gpt02_0 is usable as a PWM. By default, the channels are set to both_AB; as reported in dmesg, the duty cycle must be set differently.
Example of using a single PWM (switching to single-channel mode):
echo 0 > /sys/class/pwm/pwmchip1/export echo channel_B > /sys/class/pwm/pwmchip1/device/gpt_channel
PWM configuration and enablement:
echo 1000000 > /sys/class/pwm/pwmchip1/pwm0/period echo 500000 > /sys/class/pwm/pwmchip1/pwm0/duty_cycle echo 1 > /sys/class/pwm/pwmchip1/pwm0/enable
The pin controlled in this example is CN24.28.
Channel A is routed to pin J54.27, next to the pin shown in the image.

root@desk-t2h-usd-devel:~# stty -F /dev/ttySC1 115200 -echo -echoe crtscts
Attach the BLE module:
root@desk-t2h-usd-devel:~# hciattach /dev/ttySC1 any 115200 flow Device setup complete
Check if the interface is blocked using rfkill:
root@desk-t2h-usd-devel:~# rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
1: hci0: Bluetooth
Soft blocked: yes
Hard blocked: no
root@desk-t2h-usd-devel:~# rfkill unblock 1
