[LinuxBIOS] smartcore-p5 fails to elfboot both FILO and etherboot
by Kjell Svensson 14 May '05

14 May '05

Hi LinuxBIOS list subscribers, I've been struggling for a couple of days now trying to get LinuxBIOS working on a DigitalLogic SmartCore-P5 166MHz PC/104 card. I am using the v1 tree, since the v1 tree contained smartcore support, but the v2 tree does not. I had no problems building and flashing the LinuxBIOS, and it starts up just fine and ends up in elfboot as expected. Elfboot reports to find my payload, loads it, and attempts to start executing it. At that point, nothing more happens. Due to the limited "debugability" at this point, it's hard to say exactly what has happened, but a serial output character I have put early in the FILO startup code is not showing up so I guess the FILO code is never reached at all(?) I have verified that the filo elf image I'm trying to load is OK by loading it from GRUB (it worked OK). I have searched both the archives and other parts of the Internet for some hints about this, but the only interesting thing I was able to find was a FAQ in the FILO tree saying there was a bug in some linuxbios/elfboot checksum calculation routine that would cause FILO to crash. According to that FAQ, using the latest linuxbios patches should fix this problem. But I couldn't find any patches newer than the v1 stable tree, so I assumed this was old info(?)... Does this sound familiar to anyone? Any suggestions would be highly appreciated. The v2 tree contains support for another DigitalLogic card that I'm not familiar with. Would there be any chance that config would work on my SmartCore-P5 card? Cheers, /Kjell

RE: [LinuxBIOS] flash issue with AMD Ref board

what is EEPROM in your BIOS socket? How do you install your DIMM? 4x1G in CPU0? What is your cpu version? YH _____ From: beneo [mailto:beneo@comcast.net] Sent: Wednesday, May 11, 2005 6:57 PM To: linuxbios(a)openbios.org Subject: [LinuxBIOS] flash issue with AMD Ref board 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. 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. 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. could anybody give me some pointer on what to check? 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. Thanks Beneo

Re: [LinuxBIOS] makefile for Windows

Apparently it does not run. I started modifying the commands in the makefile, and started compiling rombios.c I am getting this error: rombios.c:2662:1: pasting "(" and ""ata_cmd_data_in : read error\n"" does not give a valid preprocessing token the source line is: BX_DEBUG_ATA("ata_cmd_data_in : read error\n"); Do you think it is due to the environment?

some GPIO need to be enabled. I guess. You need to check the schematic in AMD NDA web site to find out which GPIO control that.
