@kiki Selfmade!
Cross compiled Ingredients:
- Preloader from Altera or ARM tf-A depending on System
- Linux Kernel 6.1
- U-Boot
- Root-fs from buildroot
Its kinda like using Arch but more bare metal. -

Yep I too thought about building a Linux distro from scratch… openrc + openbox
I never expected embedded Linux to be this performant boot wise. On a Cyclone V HPS (800Mhz, Coretex A7) the entire system boots in 3s. Thats from power on to a shell in userspace. And it uses like 40MB of SD-Card Space. The entire speed gets throuwn out the window as soon as you use systemd. Then it takes like five times as long. I kinda want to explore this further in the future by addin LCD support with a desktop environment and get some numbers for that. Currently very happy with the results.
