Other platforms

If you want to work on another plateform that we don't support, here are a few notes.

MacOS ARM

I don't know if that's possible and how to it, but if you want to figure that out:

ask the assistants and teachers about the feasability
look at what needs to be installed by reading our automation with Ansible in sye.yml and base.yml
look at already solved errors under troubleshooting.md to find some hints
please contribute here what you found and how to fixed the errors you encountered (shoot me an email at samuel.roland at master dot hes-so.ch).

good luck !

Arch setup

I don't have time to test this but some friends have figured out this list of packages, tested in Docker. Thanks to Kenan Augsburger and Mario Ferreira to have contributed these Arch commands !

See details

pacman -Suyy
pacman -S wget dnsmasq net-tools musl make cmake mtools uboot-tools dtc gcc qemu-system-arm qemu-system-aarch64 sudo arm-none-eabi-gcc dosfstools bridge-utils
paru -S ncurses5-compat-libs python2-bin # for debug

When building SO3, if you have an issue with a yaml thing, Mario Ferreira has made this little patch, you can create a file named fix_libyaml_compilation.diff including this

See file

diff --git a/so3/scripts/dtc/Makefile b/so3/scripts/dtc/Makefile

and then apply the patch with git apply ./fix_libyaml_compilation.diff. Just make sure to not commit these changes in your lab.
