I've just received my UART dongle and I could see that indeed something
has been sent over UART.
The first error seen was about the fact only ECC DIMMs are allowed, in
the devkit they provide
non-ecc memory. Is it normal coreboot only supports ECC DIMMs?
I've then plugged some nice kingston DIMM with ecc and what I get then
is an exception :
Unexpected Exception: 13 @ 10:00002f08 - Halting
Code: 4096 eflags: 00010282
eax: 002163b6 ebx: 0000c000 ecx: 0000227e edx: fffffffe
edi: 0000eb02 esi: 0000f444 ebp: 0000bebc esp: 0000bebc
As soon I get this exception, the 7 segments display : FF
I guess if this is the first thing I get, coreboot has a problem not the
Could you tell me which coreboot version from the 1.3 tree you have been
using when you
validated the port?
