Hello Matt,
Thank you for the reply. I just unset CONFIG_MALLOC_UPPERMEMORY. Then keyboard worked for me.
Just one more clarification. The capslock/numlock LEDs doesn't work. Did you observe the same behaviour?

Regards,
Omkar

Broadwell-DE platform requires SeaBIOS config to have '# CONFIG_MALLOC_UPPERMEMORY is not set' so be sure that is unset in yours. I've also heard that disabling CONFIG_PMTIMER is necessary but haven't tested that myself.  On the 3 Broadwell-DE boards I tested, USB was only functional in SeaBIOS with CONFIG_MALLOC_UPPERMEMORY unset, with MRC cache disabled, and with the FSP debug level set to 3. Any of those conditions not met resulted in non-functional USB under SeaBIOS. YMMV.

Hello everyone,
I'm trying to boot camelback mountain with coreboot image. I selected the seabios as primary payload. I attached USB keyboard.
In the boot log, I'm able to see "USB is initialised",  "1 device found on USB port". So I think USB is initialised properly.
But when I press escape key continuously while booting, the boot menu is not displayed at all. Even on pressing num lock, the num lock led doesn't glow. It looks like keyboard is not even powered on.
Please let me know how to resolve this issue.
Thanks in advance,
Omkar
