[m920q] No display output

[abhas]

I just compiled both the SeaBIOS version as well as the edk2 version. The compilation process went off file. I had dumped the original BIOS from the flash chips earlier.

However, there was no display output with either of these coreboot binaries. I would love to help debug / fix this issue.

I'm attaching a screenshot of the coreboot compilation output.

If you have both DIMM sockets filled, I had a similar issue. You need to take out the DIMM1 and leave in DIMM0. I tracked it down to a specific change in coreboot. I am not sure what is meant by "catch potential configuration errors early on" or how this is resolved.

SIDE NOTE: The edk2 isn't completing initialization, the bootsplash appears but then hangs. I will investigate this later today. This seems to be working now.

Thank you very much for this tip! It helped me boot the board finally! :)

Let me recompile, re-flash and test out.

I'll add this to the readme as well but if you have any more issues, you can't resolve you read the debug output using a serial com port (search for the part number FRU 04x2733) and a USB to male serial adapter. Then on another computer use a serial TTY program like minicom or tio. When all connected all I had to do run run sudo tio /dev/ttyUSB0 then realized it was too much information and did it again but outputted to a log file. Make sure you start the program before turning on the M920q.
