[LinuxBIOS] flash issue with AMD Ref board<BR></FONT><BR></DIV>
<DIV></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'm playing with the AMD seranede board. The
flash_and_burn utility can not program linuxBIOS to the flash. but I
can read the linuxbios and save to a file correctly.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>If I boot from AMI BIOS, using same utility, I
can program a linuxBIOS into the flash. That made me believe some
setting by linuxBIOS on the AMD Ref board is not right. I just don't know
what.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I used gdb to trace the code, Flash_and_burn
utility enables flash by program two AMD Southbridge 8111 registers, One for
enable 4MB window to flash (DevB, 0x43), one for enable write to the flash
(DevB, 0x40). I checked the AMD datasheet, it seems all it need. But if I
boot with LinuxBIOS, the flash erase command has no effect. with AMI BIOS, I
can sucessfully erase a sector. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>could anybody give me some pointer on what
to check? </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I should add, the linuxBIOS only reports 2GB
memory when I really have 4GB in the system. I don't know if this have
something to do with my issue.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks </FONT></DIV>
