A week ago I wrote here about my problems trying to port coreboot to my board. Unfortunately I am still no closer to booting.
In the meantime I flashed my new chip with my OEM firmware backup. It boots; then I flashed my patched IFD (for chip ID and flash unlock) and it still boots. So it's not chip compatibility or corrupted descriptor.
The only sign of life I got is the bootblock banner left in the SPI console. My PCI POST card is showing nothing, but knowing that it sits on a PCIe-PCI bridge (ASM1063 that P8Z77M-PRO does not have) and not knowing if it needs software init to work, I am now trying to pull POST codes off the LPC bus over the TPM header, using an Arduino Due. Do I have to add some early init to have port 80 accesses sent to LPC bus for this to work?
Thanks for your help Keith
