Re: Boot Linux through GRUB2 on AMD DB-FT3b-LC

[Grigore Lupescu]

Hello Andrei,

Unfortunately not - I cannot attach a serial. My only options excluding HDMI output are LPC (ordered header) and USB (with hacks, don't want to try this one yet). Any suggestions on debug would definitely help.

From the looks of it it might be a Coreboot problem rather than a GRUB2 problem but I am trying to wage out the possibility of something in the middle.

Problem1 - Overflow each time I reach end of screen

Problem2 - Linux doesn't boot. I execute the below to boot:

grub> set root=(hd0,gpt2)

grub> linux /boot/vmlinuz-4.4...-generic root=/dev/sda2

grub> initrd /boot/initrd.img-4.4...-generic

grub> boot

I use a USB to SATA drive where I have the SSD plugged in (and legacy Ubuntu Linux x64 4.4 on it).

### 1 ### Everything works

AMI BIOS 2.17.1246

Core Version 4.6.5.4

UEFI 2.3.1; PI 1.2

AMI BIOS + GRUB2.02beta2-36ubuntu3.1 => terminal_output=gfxterm, see USB-SATA SSD as (hd0), (hd0, gpt0).., works both on USB2.0 and USB3.0.

### 1 ### Overflow screen + cannot boot Linux

Coreboot latest + GRUB2.02beta3 => terminal_output=vga_text, see USB-SATA SSD as (usb0), (usb0, gpt0).., works only on USB2.0.

Thank you,

Grigore
