[coreboot] Nothing hdmi displayed on FT3B-LC

[Grigore Lupescu]

Hi Wolfgang,

Thank you for your suggestions. The actual thing that did the trick was
setting the display framebuffer graphics resolution to something (e.g.
1024x768 64k, some other combinations also work). I think the other
settings (e.g. VGA BIOS) were already set by setting the board (amd
ft3b-lc).

At this point though I have another problem. I have set GRUB2 as payload
(2.02 beta3, latest version HEAD) and it appears that the console buffer
and/or video buffer have an overflow problem - when I fill up the screen
i.e. big output (or progressive newline output) GRUB restarts.

Problem is any command I run will most likely fill up the screen and GRUB
will restart. I suspect that even booting Linux determines GRUB to restart
because of this.

1. Is this a known issue ? (overflow on GRUB cli screen)
2. Could I avoid not getting screen outputs from GRUB ?
3. Can Coreboot give me info on the GRUB crash on the display ? (being it
is the only way to interact)

Thank you,
Grigore
