Hi guys,
I made the jump into the ivybridge world, sort of head first, and now I need help.
I put my result so far on gerrit: https://review.coreboot.org/c/coreboot/+/38988
I got nothing trying to boot it. No video. No serial. The closest resemblance of "life" is a bootblock banner in the SPI console I pulled off my flash chip, but its date is so wrong (Feb 3 vs. today, Feb 18) I can't trust that, so I effectively have nothing, and I essentially know nothing when it comes to dealing with an ME platform, as you know my good old i440bx has none of these crap. I don't even know where to start looking.
Here's what I did. - Complete vendor firmware dumped off original SPI chip. - Extracted descriptor and ME binary, VBT. I can get at the VGA BIOS if needed - ME to remain intact until I get this to boot. - flashrom layout saved - Unlocked IFD with ifdtool - Patched the chip id in #2 of 3 VSCCs in IFD to match my new flash chip (W25Q64JVSSIM), was 0xef,0x40,0x17, now 0xef,0x70,0x17 - Run autoport while still on OEM firmware. - Incorporated stuff from p8z77-m_pro which autoport didn't provide. - Resized the CBFS to cover the entire IFD bios region - Put dumped IFD and ME blob into config. Build. Flash. frser-duino on Mega2560 R3 w/ Hoodloader2 is slow, but works.
Board has a serial port, and I have a serial cable that should work, one that I tested after booting into systemrescuecd on a USB drive on OEM firmware. I'm attaching pretty much everything I have handy besides the actual port itself, in the gerrit link above.
I am now a lost pig. Appreciate all help. Do tell me what else I need to put up.
