coreboot-builder-scripts VS auto-1vyrain

Have you tried building just coreboot for the w541 yet? I would suggest doing that if you haven't. I need to update it, but this what I used. Due to flaky connections to the chromebook images, I sourced the mrc.bin from skulls. This is the proper way to do it.

You can Skull's build scripts are based on my coreboot-builder-scripts, which does rely on x86 Docker. You can build on coreboot on an RPi but you need to compile crossgcc. I have not done this myself in sometime and the only tutorial I know if the Karl Cordes's x220 tutoial. While the dependencies are outdated the crossgcc build command is likely the same.

I finally got it! Long story short, I used the coreboot-sdk docker image for the toolchain through the great coreboot-builder-scripts repository (it needs a couple adjustments that I've detailed in this other thread: OpenBSD in Thinkpad x220 with Coreboot 4.7.

We can use the https://github.com/Thrilleratplay/coreboot-builder-scripts to use the coreboot-sdk toolchain and compile Coreboot 4.7, however we need to make a couple of adjustments:

Docker images can be built and/or pulled from a repository like hub.docker.com. Here is the link to coreboot-sdk but would suggest looking at other Docker images like the official NextCloud image to get a better sense of how standalone Docker image applications can be configured. If you want a better idea of how to use the coreboot-sdk, I use it in my coreboot-builder-scripts
