Coreboot development on the Librem

[slim2k]

I have a Librem 15 Version 3 … I would like to re-flash coreboot with my own Linux payload so I can start some processes that provide security-related services to the host OS…

Is the Librium a good choice to do this on? Ideally I would be able to deploy many times from the command line … I gather flashrom can do this…

I believe this is what you need

Building coreboot from source (official script)

Hello all, I’ve finished writing a build script to build coreboot from scratch. You can grab it from here: https://source.puri.sm/youness.alaoui/coreboot-files/raw/master/build_coreboot.sh Advantages of this script: You’ll build coreboot yourself and be sure that nobody has tampered with it. You’ll update your machine to the latest version (see the change log to know what each new version brought). Some of the feature updates include: 2017-08-21: Fix “coreinfo” 2017-10-12: The script now …

btw it’s *Librem

Should be fairly “easy” to do with the Librem as it already comes with coreboot, and there is a build script to let you build coreboot from scratch and it verifies the hashes to make sure the build is correct.
If you do wish the modify the coreboot image (such as replacing seabios with a linux payload), then I would very strongly suggest you buy hardware flashing material in order to recover the flash in case the machine doesn’t boot. Whenever you attempt something like this, expect to get 100 bricks before you manage to find the right configuration to make it boot properly, so being able to recover with a hardware flasher is necessary.
