Hi there,
I use grub as coreboot’s payload and successfully get the “grub>” prompt. Then
I use following commands try to bring-up my linux kernel:
set isofile="/core-image-minimal-mohonpeak64.iso"
loopback loop (usb0,1)$isofile
linux (loop)/vmlinuz root=/dev/ram0 iso-scan/filename=${isofile} console=tty1
console=ttyS1,115200n8 ramdisk_size=102400
initrd (loop)/initrd
boot
The boot process was successful until the last step and before displaying login
prompt, only one blinking cursor left. I expect it was redirected to other
serial port but I don’t know how to connect to it. Following is my grub.cfg:
serial --unit=1 --speed=115200 --word=8 --parity=no --stop=1
terminal_input --append serial
terminal_output --append serial
#
# Sample GRUB configuration file
#
echo 'Hello world!'
# Boot automatically after 30 secs.
set timeout=30
Is there someone that can help? Thanks.
