Hi All,
I am able to get the serial ouput.But after printing the output "Jumping to LinuxBios". It does show nothing. I am pasting here the output of serial console. Can anybody have a look and suggest something to go ahead. ---- LinuxBIOS-2.0.0.Fallback Fri Feb 9 12:11:33 PST 2007 starting... 01 is the comm register SMBus controller enabled vt8606 init starting 00000000 is the north 1106 0605 0120d4 is the computed timing NOP PRECHARGE DUMMY READS CBR MRS NORMAL set ref. rate enable multi-page open Slot 00 is SDRAM 10000000 bytes 0100 is the chip size 000e is the MA type Slot 01 is empty Slot 02 is empty Slot 03 is empty vt8606 done Testing DRAM : 00000000-000a0000 DRAM fill: 00000000-000a0000 00000000 00010000 00020000 00030000 00040000 00050000 00060000 00070000 00080000 00090000 000a0000 DRAM filled DRAM verify: 00000000-000a0000 00000000 00010000 00020000 00030000 00040000 00050000 00060000 00070000 00080000 00090000 000a0000 DRAM range verified.
