Reliable Embedded Systems – Robert Berger e.U. build framework & “evil vendor tree”
Objectives
Can the Reliable Embedded Systems – Robert Berger e.U. Yocto Project®/OpenEmbedded build environment be used in combination with an “evil vendor tree”? Yes for sure! We’ll build an image – a “core-image-minimal” – for the phyBOARD®-Sargas STM32MP15 and we’ll deploy it to an SD card.
Prerequisites
Assuming you already have the Reliable Embedded Systems – Robert Berger e.U. Yocto Project®/OpenEmbedded build framework installed you are in a good position and can skip the chapter “Install a minimal Build framework”.
Install a minimal Build framework
Install docker
sudo apt install docker.io
sudo usermod -aG docker ${USER}
sudo reboot
Create a directory where you have plenty of space
mkdir -p ~/projects/resy-playground cd ~/projects/resy-playground
Convenient symlink on the host
sudo ln -sf ~/projects/resy-playground /workdir
You might need to fix some permissions.
On host machine
Start docker build container
student@e450-7:/workdir⟫ cd /workdir wget https://raw.githubusercontent.com/RobertBerger/manifests/master/phytec/resy-poky-container-evl-phycore-stm32mp1-pd21.1.0.sh chmod +x resy-poky-container-evl-phycore-stm32mp1-pd21.1.0.sh ./resy-poky-container-evl-phycore-stm32mp1-pd21.1.0.sh
In container
The first time only
pokyuser@e450-7:/workdir$ mkdir -p /workdir/3rd-party/phyboard-sargas cd /workdir/3rd-party/phyboard-sargas wget https://download.phytec.de/Software/Linux/Yocto/Tools/phyLinux chmod +x phyLinux
This you’ll need to do not only the first time
cd /workdir/3rd-party/phyboard-sargas ./phyLinux init
repo tool wrapper is installed: /usr/bin/repo
no repo repository in current directory
installing repo tool
using repo-1 branch of upstream repo-tool
if you want to use newer branches, you need to use pyhton >= 3.6
no repository initialized
Initializing from an empty directory
updating remote phytec repo repository

Create an SD card image
This is a very strange way and should be done from within BitBake via e.g. a .wic file, but hey it’s an “evil vendor tree”.

WARNING: before to use the command dd, please umount all the partitions
associated to SDCARD.
sudo umount `lsblk --list | grep mmcblk0 | grep part | gawk '{ print $7 }' | tr '\n' ' '`
To put this raw image on sdcard:
sudo dd if=flashlayout_core-image-minimal/trusted/../../FlashLayout_sdcard_phycore-stm32mp1-2-trusted.raw of=/dev/mmcblk0 bs=8M conv=fdatasync status=progress
(mmcblk0 can be replaced by:
sdX if it's a device dedicated to receive the raw image
(where X can be a, b, c, d, e)

On the host system – Flash the SD card
On the host navigate to where the SD card image was built
pushd /workdir/3rd-party/phyboard-sargas/build-openstlinuxeglfs-phycore-stm32mp1-2/tmp-glibc/deploy/images/phycore-stm32mp1-2
Make sure you figure out what’s the mount of your SD card. In my case it’s /dev/sdc.
time sudo bmaptool copy --nobmap FlashLayout_sdcard_phycore-stm32mp1-2-trusted.raw /dev/sdc
bmaptool: info: no bmap given, copy entire image to '/dev/sdc' bmaptool: info: 100% copied bmaptool: info: synchronizing '/dev/sdc' bmaptool: info: copying time: 2m 23.0s, copying speed 10.7 MiB/sec real 2m23.180s user 0m0.234s sys 0m2.072s
Please note, that secure boot is not something we typically want for development. One reason is, that flashing with sdwire takes a significant amount of time (35m 34.3s), since the bmap tools need to write every single bit and can not use the bmap information for optimized write.
sudo bmaptool copy --nobmap FlashLayout_sdcard_phycore-stm32mp1-2-trusted.raw /dev/sde bmaptool: info: no bmap given, copy entire image to '/dev/sde' bmaptool: info: 100% copied bmaptool: info: synchronizing '/dev/sde' bmaptool: info: copying time: 35m 34.4s, copying speed 736.9 KiB/sec

What is the kernel version?
root@phycore-stm32mp1-2:~# cat /proc/version Linux version 5.4.56 (oe-user@oe-host) (gcc version 9.3.0 (GCC)) #1 SMP PREEMPT Wed Aug 5 07:59:52 UTC 2020
Let’s have a look at currently loaded kernel modules:
root@phycore-stm32mp1-2:~# lsmod Module Size Used by sch_fq_codel 20480 2 ipv6 442368 18 nf_defrag_ipv6 20480 1 ipv6
What is the content of the kernel command line?
root@phycore-stm32mp1-2:~# cat /proc/cmdline root=PARTUUID=e91c4e10-16e6-4c0e-bd0e-77becf4a3582 rootwait rw drm.edid_firmware= console=ttySTM0,115200
Conclusion
That’s just a small demo of how a “Build Container” can be used with “Vendor Trees”.
Please note: Poky is not used by the “Evil Vendor Tree”. Poky is the reference implementation of the Yocto Project®.
