[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>
