Updating PNOR/BMC firmware on talos II Lite
« on: September 28, 2024, 09:12:25 pm »
Hey all,

I'm trying to get my NAVI10 AMDGPU to work with my Talos II lite. I've got the firmware in BOOTKERNFW. Just not sure if that requires an up-to-date PNOR cause this PNOR/BMC is from 2018. Just wondering if I need to update the PNOR to a more modern one to get the firmware to load.

I went on a major month-long mission bricking and re-flashing the BMC/PNOR to discover that my system won't work with the new PNOR/BMC, I even had to get a CH341a to flash it manually. Maybe this is because it's a special developer system with DD2.1-stepped CPU?. Also, I can't build the old version of OpenBMC due to bitbake having fetch issues with github.com, so it's not like I could patch BMC/PNOR myself which sucks, I guess I could bisect the code and figure it out but that would be like 50+ hours of work.

Maybe the solution for me is just to use coreboot or HEADS or something simpler. Does anyone know what the state of that is?

You probably should be running the most current firmware anyway; there are other improvements. You don't need to update the FPGA, just the PNOR to get Petitboot up to date.
