Hello everyone, I am currently bringing up an AMD Cezanne/Renoir laptop board on coreboot and have run into an FSP-S initialization issue that I am trying to understand better.
The board hangs immediately after entering FSP-S. The boot log shows a successful bootblock, romstage, FSP-M, and ramstage, but execution stops right as FSP-S is about to be entered. I suggest that FSP-S crashes or hangs immediately upon entry I found some related information from StarLabs, which appears to describe a similar FSP issue that has not yet been fixed by AMD[1]. >From what I can see, the CEZANNE_S.fd file was uploaded about three years ago and has not been updated since. Does anyone know what the underlying problem is here? StarLabs also have a WIP patch[2]. The change description states: "Works perfectly, apart from having no PCI devices." In my case, even disabling almost every device in the devicetree (and physically removing hardware) does not seem to have any effect on the hang. It also looks like most AMD boards currently in the coreboot repository target Chromebooks. Are those boards working correctly with regard to FSP-S? Does anyone know what should be configured so that FSP-S will not crash on Cezanne/Renoir systems? Any insight or guidance would be very helpful. Thank you!
