Minimalist Linux distribution¶
Goal¶
- In this tutorial you will:
create Linux distribution using Yocto (along with support firmware) based on Vivado project created earlier
boot Linux on Leopard DPU through EGSE Host
A bit of background¶
Running Linux on device like Leopard DPU requires set of artifacts
Boot firmware (in particular first stage bootloader and U-Boot)
Linux kernel
Device tree
Root filesystem
Yocto can build these items automatically. Developers construct project using Yocto from layers coming from Yocto project itself, hardware manufactures and their own. Each layer contributes series of recipes that are describing how to build particular components of Linux distribution. BitBake tool manages all dependencies between recipes and hides build complexity.
After building all required artifacts you can use Leopard DPU boot capabilities to load boot firmware into persistent memory and load Linux kernel and root filesystem from network.
Prerequisites¶
.xsafile with platform configuration from Create minimalist Vivado projectMachine with Linux edition supported by Yocto
Tools installed on machine:
libtinfo5(required by Xilinx layers)Yocto requirements (https://docs.yoctoproject.org/ref-manual/system-requirements.html#required-packages-for-the-build-host)
At least 120GB free space for Yocto build
Provided outputs¶
Following files (Tutorial files) are associated with this tutorial:
Leopard/Zero-to-hero/02 Minimalist Linux distribution/boot-common.bin- Boot firmware for LeopardLeopard/Zero-to-hero/02 Minimalist Linux distribution/dpu-leopard-leopard-dpu.rootfs.cpio.gz.u-boot- Root filesystem for LeopardLeopard/Zero-to-hero/02 Minimalist Linux distribution/Image- Linux kernelLeopard/Zero-to-hero/02 Minimalist Linux distribution/system.dtb- Device tree
Use these files if you want to skip building Yocto distribution by yourself.
Create project Yocto¶
Create new directory for Yocto project and navigate to it.
machine:~$ mkdir ~/leopard-linux-1 machine:~$ cd ~/leopard-linux-1 machine:~/leopard-linux-1$Clone Poky layer from Yocto project
machine:~/leopard-linux-1$ git clone -b nanbield https://git.yoctoproject.org/poky sources/pokyCreate new build configuration
machine:~/leopard-linux-1$ source sources/poky/oe-init-build-env ./build You had no conf/local.conf file. This configuration file has therefore been created for you from ~/leopard-linux-1/sources/poky/meta-poky/conf/templates/default/local.conf.sample You may wish to edit it to, for example, select a different MACHINE (target hardware). You had no conf/bblayers.conf file. This configuration file has therefore been created for you from ~/leopard-linux-1/sources/poky/meta-poky/conf/templates/default/bblayers.conf.sample To add additional metadata layers into your configuration please add entries to conf/bblayers.conf. The Yocto Project has extensive documentation about OE including a reference manual which can be found at: https://docs.yoctoproject.org For more information about OpenEmbedded see the website: https://www.openembedded.org/ ### Shell environment set up for builds. ### You can now run 'bitbake <target>' Common targets are: core-image-minimal core-image-full-cmdline core-image-sato core-image-weston meta-toolchain meta-ide-support You can also run generated qemu images with a command like 'runqemu qemux86-64'. Other commonly useful commands are: - 'devtool' and 'recipetool' handle common recipe tasks - 'bitbake-layers' handles common layer tasks - 'oe-pkgdata-util' handles common target package tasks machine:~/leopard-linux-1/build$
Add layers Yocto¶
Clone Xilinx layers:
machine:~/leopard-linux-1/build$ git clone -b nanbield https://github.com/Xilinx/meta-xilinx.git ../sources/meta-xilinx machine:~/leopard-linux-1/build$ git clone -b nanbield https://github.com/Xilinx/meta-xilinx-tools.git ../sources/meta-xilinx-tools machine:~/leopard-linux-1/build$ git clone -b nanbield https://git.openembedded.org/meta-openembedded/ ../sources/meta-openembeddedAdd set of required layers from Xilinx repositories:
machine:~/leopard-linux-1/build$ bitbake-layers add-layer ../sources/meta-xilinx/meta-xilinx-core machine:~/leopard-linux-1/build$ bitbake-layers add-layer ../sources/meta-xilinx/meta-xilinx-bsp machine:~/leopard-linux-1/build$ bitbake-layers add-layer ../sources/meta-xilinx/meta-xilinx-standalone machine:~/leopard-linux-1/build$ bitbake-layers add-layer ../sources/meta-xilinx-tools machine:~/leopard-linux-1/build$ bitbake-layers add-layer ../sources/meta-openembedded/meta-oe/ machine:~/leopard-linux-1/build$ bitbake-layers add-layer ../sources/meta-openembedded/meta-networking/Note
After adding Xilinx layers, BitBake might report warning
The ZynqMP pmu-rom is not enabled (…) To enable this you must add ‘xilinx’ to the LICENSE_FLAGS_ACCEPTED to indicate you accept the software license.
This is for informational purposes only and you can ignore it.
Clone KP Labs layers
machine:~/leopard-linux-1/build$ git clone -b nanbield https://github.com/kplabs-pl/meta-kp-classes.git ../sources/meta-kp-classes machine:~/leopard-linux-1/build$ git clone -b nanbield https://github.com/kplabs-pl/meta-kp-leopard.git ../sources/meta-kp-leopardAdd set of required layers from KP Labs repositories:
machine:~/leopard-linux-1/build$ bitbake-layers add-layer ../sources/meta-kp-classes/ machine:~/leopard-linux-1/build$ bitbake-layers add-layer ../sources/meta-kp-leopard
Create layer for customizations Yocto¶
Create empty layer
machine:~/leopard-linux-1/build$ bitbake-layers create-layer ../sources/meta-localAdd newly created layer to project
machine:~/leopard-linux-1/build$ bitbake-layers add-layer ../sources/meta-localVerify set of layers enabled in project by opening

Build project Yocto¶
Build project artifacts:
machine:~/leopard-linux-1/build$ bitbake leopard-allWarning
First build might take a long time to complete. Be patient.
Prepare build artifacts for transfer to EGSE Host
machine:~/leopard-linux-1/build$ mkdir -p ../build/egse-host-transfer/ machine:~/leopard-linux-1/build$ cp tmp/deploy/images/leopard-dpu/bootbins/boot-common.bin ../build/egse-host-transfer/ machine:~/leopard-linux-1/build$ cp tmp/deploy/images/leopard-dpu/system.dtb ../build/egse-host-transfer/ machine:~/leopard-linux-1/build$ cp tmp/deploy/images/leopard-dpu/dpu-leopard-leopard-dpu.rootfs.cpio.gz.u-boot ../build/egse-host-transfer/ machine:~/leopard-linux-1/build$ cp tmp/deploy/images/leopard-dpu/Image ../build/egse-host-transfer/Transfer content of

Summary¶
In this tutorial you’ve built minimal Linux distribution for Leopard DPU using Yocto and XSA file prepared with platform configuration. After copying build artifacts to EGSE Host you’ve written necessary boot firmware to DPU boot flash. You’ve also prepared U-Boot script for booting from network and observed boot process in minicom terminal. Finally you’ve logged in to DPU and verified that Linux is running.
