So I'm not sure if this is a coreboot issue - sorry in advance if not - but I have to start somewhere:
I'm connecting to an embedded device using a serial port (rs232). This device starts Coreboot, then syslinux (extlinux) and finally a custom linux distribution. Sometimes I want to stop syslinux and choose another boot option (in its boot prompt) - by clicking the ESC key.
My problem is: the keyboard doesn't work, i.e. I get the boot prompt, but can't write. I've already tried adding sgabios to our precompiled coreboot rom, as per [1], and I can check that it was added (I suppose), given cbfstool's output:
Name Offset Type Size vsa 0x0 stage 57532 vgaroms/sgabios.bin 0xe100 raw 4096 (empty) 0xf140 null 3608 fallback/romstage 0xff80 stage 18947 fallback/coreboot_ram 0x14a00 stage 89248 fallback/payload 0x2a700 payload 40356 (empty) 0x34500 null 309256
but still, the keyboard doesn't work. Is this not a coreboot issue? What can I do to further debug the problem?
ps: when answering please add me to CC as I'm not subscribed to the mailing list
