As the XELK kit is based on Yocto, the implementation of the MVM follows the approach described here. As such, the reading of this section is highly recommended.

Introduction[edit | edit source]

This is a quickstart guide to build Yocto BSP for Axel SOMs, to rebuild the binaries (U-Boot, Linux kernel, root file system) provided with XELK releases.

For more information regarding Yocto build system, go to its dedicated category page

Build System prerequisites[edit | edit source]

XELK MVM is already configured to build this Yocto version/configuration, however, users typically don't use a VirtualBox VM for Yocto builds for performance reasons.

You can refer to Yocto manual setup section for a list of supported Linux distribution and their configuration to create your own build environment on your favorite distribution.

Build the XELK Yocto BSP[edit | edit source]

Initialize the build environment[edit | edit source]

XELK Yocto BSP uses git-repo tool to fetch all the required git repositories to build 

dvdk@dvdk-vm:~/axel$ curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > repo
dvdk@dvdk-vm:~/axel$ chmod a+x repo
dvdk@dvdk-vm:~/axel$ ./repo init -u git@git.dave.eu:axel/axel-bsp.git -b axel-morty
dvdk@dvdk-vm:~/axel$ ./repo sync

Build the Yocto BSP image[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 20GiB of disk space is required for the build. Moreover, building inside the DVDK adds some overhead, 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, developers should 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 DVDK (eg: adding more cores and disk space)

Once completed the initialization phase, developers can launch the Yocto image build process with the following commands: 

dvdk@dvdk-vm:~/axel$ DISTRO=fsl-imx-fb MACHINE=imx6qxelk source axel-setup-release.sh -b build-fb
dvdk@dvdk-vm:~/axel/build$ bitbake axel-image-qt5

The resulting files (kernel, devicetree and u-boot binaries, plus .tar.gz root file system) will then be available inside build/tmp/deploy/images/axel.

Generating the SDKs[edit | edit source]

After creating an image as described above, the corresponding SDK can be generated by issuing the following command: 

bitbake <target-image-name> -c populate-sdk

Again, replace <target-image-name> with one of the images listed in here.

Build additional packages[edit | edit source]

To build additional packages the user must first enter the directory where the axel-bsp-init-env.sh is placed and source it 

dvdk@dvdk-vm:~/axel$ DISTRO=fsl-imx-fb MACHINE=imx6qxelk source axel-setup-release.sh -b build-fb
dvdk@dvdk-vm:~/axel/build$

And then he can run any of the bitbake commands. 

dvdk@dvdk-vm:~/xelk/build$ bitbake memtester

The resulting packages (the default format is ipk) can be found inside build/tmp/deploy/rpm. 

dvdk@dvdk-vm:~/xelk/build$ ls -l tmp/deploy/ipk/armv7a-vfp-neon/memtester*
