Dear Maillist,
I am a bios engineer from Byosoft.
I have 3 questions about "grub2 as coreboot's payload".
(1).how can I enable serial port during post?
l add following in grub.cfg ,but it seems doesn't make sense.
//>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
# Enable serial console
serial --speed=115200 --unit=0 --word=8 --parity=no --stop=1
terminal_input --append serial
terminal_output --append serial
//<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
the log shows the serial debug message in coreboot phrase,but there's no
message about the payload:grub2 .
(2).USB & PS2 device can't be used under GRUB shell
I can boot to GRUB SHELL under QEMU emulation,but the usb & ps2 KeyBorad
can't be used.
Do I need to add something to support this?
Thanks,
TankTang
