Framework Laptop 12 13th Gen Intel Core (Sunflower)

Support Status

This port is currently not officially supported by Framework. It is a proof of concept for internal evaluation of the technical feasability of coreboot at Framework.

All mainboards sold to customers ship with BootGuard enabled. While it is possible for end users to build the image with publicly available source and binaries, flashing will not result in a bootable system.

Build

The following commands will build a working image:

make distclean # Note: this will remove your current config, if it exists.
touch .config
./util/scripts/config --enable VENDOR_FRAMEWORK
./util/scripts/config --enable BOARD_FRAMEWORK_SUNFLOWER
make olddefconfig
make -j$(nproc)

If you don’t plan on using coreboot’s serial console to collect logs, you might want to disable it at this point (./util/scripts/config –disable CONSOLE_SERIAL). It should reduce the boot time by several seconds.
