Wim, you nailed it. With a single-rank SODIMM the ASROCK IMB_A180 coreboot build succeeds.
Much obliged!
We will look into the memory controller code next, as our design will use double-rank SODIMMs.

Hello Mark,
Have you tried using a slower SODIMM yet? I have seen issues here myself that were caused by the faster especially dual rank SODIMMs.
The easy solution is to simply use a slower or single rank SODIMM. The real solution is to manipulate the AGESA code for correct initialization of the memory controller.

I'm new to coreboot, and I'm working to use it with an ASROCK IMB-A180, the H version with the LVDS port.
I've read previous posts regarding the "IMB-A180 won't boot" on this group, and tried the .config that was posted, but the result is the same.
The debugging output shows things progressing until agesawwrapper_amdinitmid is called, then the boot restarts, then stops cold at the same point:
PCI: 00:18.4 PCI: 00:18.5 Done allocating resources. BS: BS_DEV_RESOURCES times (us): entry 0 run 1095130 exit 0 POST: 0x74 Enabling resources... Fam16 - domain_enable_resources: AmdInitMid. agesawrapper_amdinitmid<garbage characters> Tue Feb 4 16:46:38 PST 2014 starting...
Any help with this would be greatly appreciated. Full serial debug output and .config are attached below.
