* By default, ARM cores frequency is set to 667 MHz and the [[Creating and building example Vivado project (BELK/BXELK)|example Vivado project]] is implemented for a "-1" device. This choice makes the software released with the kit compatible with possible variants based on different SoM models. In this regard, see also the [[#Order codes|order codes section]].

This chapter describes how to quickly start working with the BXELK kit. The following paragraphs will guide you through the setup and installation procedures.
 +
===Kit registration===
 +
{{ImportantMessage|text='''Customers are strongly recommended to register their kits'''. Registration grants access to reserved material such as source code and additional documentation.}}
 +
 
 +
Please register your development kit by sending an email to [mailto:support-lynx@dave.eu support-lynx@dave.eu], providing the kit P/N and CODE.
 +
 
 +
===Target setup and first boot===
 +
This section describes how to quick start SBC Lynx board delivered along with BXELK kit:
 +
*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.
 +
 
 +
 
 +
[[File:SBCLynx-BXELK.png|thumb|center|600px|Target setup for first boot]]
 +
 
 +
 
 +
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.
 +
 
 +
 
 +
[[File:Xub-nor.png|thumb|center|350px|NOR flash default partitioning]]
 +
 
 +
 
 +
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 <code>mmcblk0p2</code> partition of the [[#BXELK microSD Layout|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===
 +
As stated previously, BXELK host tools are based on a [[Managed_Virtual_Machine_(MVM)|Managed Virtual Machine]]. As indicated [[#BXELK microSD Layout|here]], microSD card delivered along with BXELK includes basic version of MVM that is the default option.
 +
 
 +
In case you choose to use the [[Managed_Virtual_Machine_(MVM)#Advanced_version|''Advanced'' version]] of the MVM instead, the <code><i>project-name</i></code> to be used is <code>lynx</code>.
 +
 
 +
Either version you choose, please follow the procedure described [[Managed_Virtual_Machine_(MVM)#Installation_and_configuration|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 [[Accessing_DAVE_Embedded_Systems_restricted_git_repositories|this page]].
 +
 
 +
{{ImportantMessage|text=Either version of MVM is installed, it provides the tools required to build [[Building_U-Boot_(BXELK)|U-boot]] and [[Building_Linux_kernel_(BXELK)|Linux kernel]]. It does not include the tools required to run Yocto build system instead.}}
 +
 
 +
===Target configuration for the development stage (<code>net_nfs</code>)===
 +
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 [[Deploying_Embedded_Linux_Systems#The_development_environment|here]].
 +
In DAVE Embedded Systems development kits, this configuration is generally denoted as <code>net_nfs</code>. U-Boot bootloader supports this configuration. Some U-Boot environment variables are needed to set it up. They are detailed [[Booting_Linux_Kernel#Configuration_net_nfs|here]].
  
 +
For more details about TFTP and NFS servers on host side, please refer to this [[Setting_up_tftp_and_nfs|page]].
 +
===Target configuration for standalone boot===
 +
Please refer to [[Standalone_boot_(BXELK)|this page]].

Introduction[edit | edit source]

BoraX SOM


BoraX Embedded Linux Kit (BXELK for short) provides all the necessary components required to set up the developing environment to:

  • build the first-stage bootloader (FSBL)
  • build the 2nd-stage bootloader (U-Boot)
  • build and run Linux operating system on BoraX system-on-module (SOM)
  • 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, composed by BoraX SOM and BoraXEVB
  • technical documentation (hardware manuals, mechanical drawings, reference schematics, application notes etc.)

Quick start guide[edit | edit source]

This chapter describes how to quickly start working with the BXELK kit. The following paragraphs will guide you through the setup and installation procedures.

Kit registration[edit | edit source]

200px-Emblem-important.svg.png

Customers are strongly recommended to register their kits. Registration grants access to reserved material such as source code and additional documentation.

Please register your development kit by sending an email to support-lynx@dave.eu, providing the kit P/N and CODE.

Target setup and first boot[edit | edit source]

This section describes how to quick start SBC Lynx board delivered along with BXELK kit:

  • 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.

Target setup for first boot


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.


NOR flash default partitioning


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, BXELK host tools are based on a Managed Virtual Machine. As indicated here, microSD card delivered along with BXELK 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.
