Introduction[edit | edit source]
SBC Lynx Embedded Linux Kit (XUELK for short) provides all the necessary components required to set up the developing environment to:
- build the bootloader (U-Boot)
- build and run Linux operating system on SBC Lynx board
- build and debug applications that will be executed on top of Yocto-based Linux distribution running on the target.
The main kit components are:
- hardware platform (SBC Lynx)
- development host released in the form of Managed Virtual Machine, tailored for Yocto-based distribution
- technical documentation (hardware manuals, mechanical drawings, reference schematics, application notes etc.)
The documents related to the software issues help the user to quickly start configuring the bootloader and the operating system, by hiding most of the complexity of the underlying hardware. Reading of the Managed Virtual Machine documentation is strongly recommended, as it plays a major role in the XUELK organization.
For more details about SBC Lynx hardware characteristics, please refer to the SBC Lynx Hardware Manual. An account for the reserved area of DAVE Embedded Systems website is required to access the kit contents.

XUELK software components[edit | edit source]
![]() |
From the software perspective, XUELK supports SBC Lynx and AXEL ULite SOM. However, physical contents of the kit include SBC Lynx only. | ![]() |
SBC Lynx Embedded Linux Kit is largely derived from the Yocto distributions released by NXP for the i.MX6 product family. For this reason most of the documentation provided by NXP remains valid for the XUELK development kit.

XUELK microSD Layout[edit | edit source]
The microSD card provided with XUELK is partitioned as shown in the following image:
Most of storage space is occupied by two partitions:
- a
FAT32
partition (mmcblk0p1
) containing:- U-Boot
bootscript
- Linux kernel and DTB binary images
- XUELK virtual machine image in OFV format (MVM basic version)
- 7-zip Windows executable file
- U-Boot
- an
ext3
partition (mmcblk0p2
) containing the root file system for the target.
bootscript
and root file system are used to boot the target as described in this section.
It is worth remembering that the microSD card is bootable, because U-Boot image is stored at address 0x400. However, even if U-Boot is run from the microSD card, the environment is retrieved from NOR flash.
How to create a bootable microSD card[edit | edit source]
Please refer to this this page.
XUELK updates[edit | edit source]
![]() |
It's recommended to use the latest available XUELK version. Please refer to Release notes for further information. | ![]() |
XUELK updating process consists of updating the Managed Virtual Machine it is based on. The procedure is described here.
Please note that this process implicitly updates git source code repositories of U-Boot and/or Linux kernel. Thus it is strongly recommended to create new local branches if you need to modify source code.
Updating git repositories[edit | edit source]
In XUELK, the following source trees are clones of DAVE Embedded Systems public git repositories:
Component | GIT Remote | XUELK Installation Directory |
---|---|---|
Linux | git@git.dave.eu:lynx/linux-2.6-imx.git | /home/dvdk/lynx/linux |
U-Boot | git@git.dave.eu:lynx/u-boot-imx.git | /home/dvdk/lynx/u-boot |
Yocto BSP | git@git.dave.eu:lynx/lynx-bsp.git | /home/dvdk/lynx/lynx-bsp |
This means that these components can be kept in sync and up to date with DAVE Embedded Systems repositories.

Target setup and first boot[edit | edit source]
This section describes how to quick start SBC Lynx board delivered along with XUELK kit (see also the following image):
- connect a TTL/USB serial cable to J42 connector; J42 pinout is:
- 1: TX data
- 2: RX data
- 3: 3.3V
- 4: GND
- on host side start your favorite terminal that will be used to interact with the target's serial console; communication parameters are 115200-8-N-1
- optionally connect the system to Ethernet LAN by plugging cable into connector J16
- connect 12V power supply to J35 connector; J35 pinout is:
- 1: GND
- 2: VIN
- insert microSD card in the slot J43.
Once power has been applied to the target, U-Boot bootloader will be fetched from the SPI NOR flash and executed. Boot messages will be printed out to the serial console. Redundant U-Boot environment is stored in the NOR flash as well, as depicted in the following image.
By default, U-Boot is configured to retrieve Linux kernel image stored in the microSD card [1]. In turn, Linux kernel shall mount root file system from the mmcblk0p2
partition of the microSD card itself. At the end of boot process, Linux shell shall be available on the serial console.
The following dump shows the typical messages printed out to the console during bootstrap process.

Host setup[edit | edit source]
As stated previously, XUELK host tools are based on a Managed Virtual Machine. As indicated here, microSD card delivered along with XUELK includes basic version of MVM that is the default option.
In case you choose to use the Advanced version of the MVM instead, the project-name
to be used is lynx
.
Either version you choose, please follow the procedure described here to install the MVM.
It is also worth remembering that access to git repositories is required to download target source code. To enable it, please refer to this page.
![]() |
Either version of MVM is installed, it provides the tools required to build U-boot and Linux kernel. It does not include the tools required to run Yocto build system instead. | ![]() |
Target configuration for the development stage (net_nfs
)[edit | edit source]
During the development stage, the target is usually connected via Ethernet LAN to the host machine and is configured to:
- retrieve binary images (i.e. Linux kernel) via TFTP protocol
- mount the development root file system via NFS protocol. This root file system is physically in the file system of the host machine as depicted here.
In DAVE Embedded Systems development kits, this configuration is generally denoted as net_nfs
. U-Boot bootloader supports this configuration. Some U-Boot environment variables are needed to set it up. They are detailed here.
For more details about TFTP and NFS servers on host side, please refer to this page.
Target configuration for standalone boot[edit | edit source]

How to update root file system on SD card[edit | edit source]
RFS update on SD card consists on expanding the new tarball compressed file on SD card ext3 partition. It is possible, for example, to perform this operation using one of the following process:
- directly on the target
- using a Linux PC (or the XUELK VM)
The ext3 partition (mmcblk0p2) containing the root file system need to be:
- erased
- written with new rfs files
Update rfs on target[edit | edit source]
- start SBC Lynx via nfs. See how to boot from nfs here
- change directory to the ext3 partition into the filesystem: typically
/run/media/mmcblk0p2
root@sbc-lynx:~# cd /run/media/mmcblk0p2 root@sbc-lynx:/run/media/mmcblk0p2#
- delete all previous files
root@sbc-lynx:/run/media/mmcblk0p2# rm -r *
- extract new rfs files from tarball archive previously copied into nfs directory (the following command assumes that xuelk-1.1.0 rfs have been already copied into VM /home/dvdk/lynx/rfs/xuelk/home/root nfs directory
root@sbc-lynx:/run/media/mmcblk0p2# tar jxvpf /home/dvdk/lynx/rfs/xuelk/home/root/xuelk-1.1.0_lynx-image-gui-sbc-lynx.tar.bz2
Update rfs on a Linux PC[edit | edit source]
- insert the SD card and check its mount point
- change dir to the ext3 SD card partition
- delete previous files and extract new files from tarball archive as described here
