getting my tinkerboard up and running

• bitbake invocation command… (what is run by ./build.sh): LANG=en_US.UTF-8 LANGUAGE=en_US.en LC_ALL=en_US.UTF-8 ../bitbake/bin/bitbake -r conf/include/rksdk.conf -r conf/include/kernel-4.19.conf -e linux-libc-headers

• the goal is to have NixOS acording to my config on it…

• installing NixOS is a bit tricky… there is a WIP nixos wiki page for the TinkerBoard 1 (https://nixos.wiki/wiki/NixOS_on_ARM/Tinker_Board) but not for the TinkerBoard 2…

• so I tried the stock OS… all of Tinker_Board_2-Debian-Bullseye-v3.0.25-20250311-release, Tinker_Board_2-Yocto-Kirkstone-1.0.2-20230919-release, Tinker_Board_2-Yocto-Kirkstone-v1.0.5-20240826-release get stuck on The TinkerBoard Splash Screen endlessly (rel: “Welche voll spezielisten habn beim OS (des zum herum probian gedacht is und nit zum fertigs produkt machn), des se zu ihrem dev-board dazu releasen by default an splash screen an… damit ma ja nit sieht, wo da boot vorgang hängen bleibt…”)

• the image from DietPi (Pasted image 20251018235412.png) after shortly showing text of i think uboot just ended up with some kind of glitched screen

• so I cloned the src and started building my own yocto image… so that I can change the kernel and uboot cmdlines to show logs instead of this stupid splashscreen

  • context: I was building this checkout repo init -u https://github.com/TinkerBoard/rockchip-linux-manifest.git -b linux4.19-rk3399-debian10 where the branch was at commit 550d09a1ec9e09915b550037e296dd9056e5c734

• probably the most hilarious bug hunt I’ve experienced

• put the nixos userspace onto the root partition, which is mounted by the kernel… can’t get it to run anything as init… Kernel ABI issue????

encounted errors

• docker container script and Docker file problems…

  • it’s a great script… it just assumes you have dpkg and apt-get in your path… xD xD

• linux-libc-headers not fetching

• “rockchip-linux” not fetching

• smth with rockchip-libmali

• mobile-broadband-provider-info not fetching … see: probably the most hilarious bug hunt I’ve experienced

• https://gitlab.gnome.org/GNOME/mobile-broadband-provider-info works … https://gitlab.gnome.org/git/GNOME/mobile-broadband-provider-info asks for auth…

  • in the bb file this “/git” is not there
  • i now know why this happens… the original URL (the gnome gitlab without the /git in the middle) fails… and yocto then goes on to trying mirrors… and one mirror it tries is original url with /git inserted…
