Thanks for the advice Marc,
I already had the loglevel set to spew (8). I additionally tried the other "Verbose output" debugging options, unfortunately I don't get any output at all when they are built in. Also, while it is hard to find and AMD doesn't have any official document confirming this, according to some google hits the processor should be revision D1 not rev E (AMD model number: OS4170OFU6DGOWOF ).
I also found the latest code not boot on my H8SCM-F mainboard with Rev D1 processor. So I have made some update to using the AGESA wrapper framework, the attachment is some of my update, with this series of patches applied, we can boot to Debian Linux Destop or Windows Server 2008 R2 standard edition. Thanks
Hi Kerry,
first of all: thanks for your effort! While I had no success at first, I now can get to the boot prompt (haven't tried any further yet).
Anyway, I currently have 2 DIMMs, each 4 GiB. A dual-channel configuration does not seem to work, the DIMMs are detected, but coreboot throws an "ASSERTION FAILED" error (see attached log cb_h8scm_01.log). It seems to fail because it somehow seems to think no DIMM is found (despite both DIMMs being detected). I tried disabling this check, but this only leads to a reset. The same problem exists with a single-DIMM configuration.
However, when I switch to a dual-DIMM, single-channel config, it at first does not start at all (i.e. no output on serial and no heartbeat from the BMC) - but when I trigger a manual reset it immediately starts up (see attached log cb_h8scm_dimma1a2_success.log).
I'll report back when I find out more.
