Lumpy should have 2GB of on-board memory and a DIMM slot that comes with a 2GB DIMM.
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 -duncan On Mon, Jul 29, 2013 at 8:14 AM, Aaron Durbin <[email protected]> wrote: > Kyösti, > > I'm not certain it's just the last entry of the e820. mrc is just > seeing 2GiB of ram and setting it up that way. > > TOUUD 0x100600000 TOLUD 0x7f200000 TOM 0x80000000 > MEBASE 0x7f800000 > IGD decoded, subtracting 32M UMA and 2M GTT > TSEG base 0x7c800000 size 8M > Available memory below 4GB: 1992M > Available memory above 4GB: 6M > > -Aaron > > On Mon, Jul 29, 2013 at 10:04 AM, Kyösti Mälkki <[email protected]> > wrote: > > On Mon, 2013-07-29 at 15:19 +0100, John Lewis wrote: > >> Where do I find/build cbmem binary? > >> > >> Please find attached dmesg. > > > > Hi > > > > I have same issue.
