Dear all,
I’ve been working on porting coreboot to the Qotom Q20331G9-S10, which uses the Intel Atom C3758R (Denverton). So far:
System boots All onboard devices are detected properly Payload (EDK II) loads fine
Issues:
1. VGA Not Working Pre-OS The board uses an AST2400 BMC for VGA output. I’ve added the VGA ROM (pulled from the official site) into the coreboot image, but no output is visible during pre-OS phase. (without the ROM, no VGA at all)
2. Console Stops After Payload The serial console works fine during the bootblock and into romstage/post. However, once coreboot hands off to the payload, the console garbles and stops showing valid output. Here’s the last clean output before it breaks:
FSP End of Firmware ... Install PPI: BD44F629-EAE7-4198-87F1-39FAB0FD717E NotifyPhaseApi() - End [Status: 0x00000000] ▒`▒f▒▒▒f▒▒▒▒`▒f▒▒▒f▒▒▒▒`▒f▒▒▒f▒▒
If anyone has any ideas, I’d love to hear your inputs. Happy to share build configs or logs if that helps.
Thanks! enzo
