Hi Ioannis, I ran into a quite similar problem - I think the wikipage needs quite some overhaul.
anyway: I also have grub2 as coreboot payload. It seems to have a memdisk, but I don't know how to change this. There is a workaround: a grub.cfg gets into that memdisk, which sources (cbfsdisk)/etc/grub.cfg - find for that in the coreboot tree. the solution then is to add a grub.cfg (and other files, like additional grub modules, background image, ...) to cbfs (in coreboot tree root): ./build/util/cbfstool/cbfstool build/coreboot.rom add -f mygrub.cfg -n etc/grub.cfg -t raw actually it's a good idea _not to_ put etc/grub.cfg at first - if you have errors in that you may end up softbricking your device. put it somewhere else and source it from the grub command line. regards, Arian On 24.07.2016 20:43, Ioannis Koutras wrote: > Hello John, > > And thanks for replying.
