revamping the build script to not use any external sources is near the top of my to-do list. In the meantime, I’ve added the option to download/flash precompiled coreboot images for all Librem 13/15 devices. While still in the testing phase (read: consider it BETA), it seems to work without issue in all my tests. From a terminal:
mkdir update && cd update
curl -LO https://source.puri.sm/coreboot/releases/raw/master/update_coreboot.sh
sudo bash update_coreboot.sh
the script will prompt you to select your model, and then a few options dependent thereof, including the ability to set the default boot order. Feedback is welcomed
edit: updated script URL to use master branch
