[coreboot] ApolloLake Oxbohill CRB GRUB2 menu on serial Console

2017-02-27 Thread Gailu Singh 
Hi Experts,

I have built grub2 with coreboot platform support (./configure
--with-platform=coreboot)
and managed to load it as elf payload in coreboot. I have added terminal
support in grub configuration coreboot.cfg as follows

serial --speed=115200 --unit=0 --word=8 --parity=no --stop=1 terminal_input
--append serial terminal_output --append serial terminal_input --append
usb_keyboard #add keyboard support.

menuentry 'Boot From Hard Disk (Linux)' { insmod (cbfsdisk)/ahci.mod linux
(ahci1,msdos1)/boot/bzImage root=/dev/sda1 resume=/dev/sda5
console=ttyS0,115200 }


While I see coreboot logs on serial console, I do not see grub2 menu on
serial console. I can see grub2 menu on HDMI display though, however my USB
keyboard is not working so not able to control grub either through display
or serial console.

Any help is appreciated.

Thanks

Hi,

Tried to change --unit=0 to --unit=2 as the serial port index used in
coreboot is 2. Still grub2 menu is not shown on serial console.
