Coreboot seems to detect the on-board memory and finds the SPD binary for it, any chance the DIMM slot is empty?Memory Straps: - memory capacity 2GB - die revision 1 - vendor Samsung CBFS: Looking for 'spd.bin' starting from 0x700000. CBFS: Found file (offset=0x7dc000, len=1536).I think the console output should show a summary after the MRC binary runs, but the verbose CBFS output is overflowing the buffer:http://review.coreboot.org/gitweb?p=coreboot.git;a=blob;f=src/northbridge/intel/sandybridge/raminit.c;h=3eb2fb3e79c01cfc8d75319b1089bb1aafde9806;hb=HEAD#l168
