Ron, How about the support of Option rom execution for on board device? Some device vendors only provide option rom instead of datasheet. Regards Yinghai Lu

quartet boot
by Stefan Reinauer 07 Aug '03

07 Aug '03

Hi, I'm having bad luck with the AMD Quartet machines currently. Due to the 4 memory controllers I had to take out quite some debug messages from auto.c to get it compile, but I don't really get to that point anyways.. all I get is the following: LinuxBIOS-1.1.0Fallback Do Aug 7 16:05:24 CEST 2003 starting... setting up resource map.... done. Enabling routing table for node 00000000 done. Enabling SMP settings setup_remote_node setup_remote_done Renaming current temp node to 00000001 done. Enabling routing table for node 00000001 done. [long delay here] Renaming current temp node to 00000002 [long delay here] done. Enabling routing table for node 00000002 [long delay here, then reset:] LinuxBIOS-1.1.0Fallback Do Aug 7 16:05:24 CEST 2003 starting... setting up resource map.... done. Enabling routing table for node 00000000 done. Enabling SMP settings [complete hang] this worked some time ago in CVS, but I don't know when it stopped. Can the resource map cause these problems? I dumped the resource map I am using from a different quartet machine, and now I get the same problems than I had before with the default resource map. It looks to me like it's a bad idea[tm] to set the resource map at all before knowing anything about the machine's resources. debugging... Stefan

DoC 2000 vs DoC Millennium
by Niki Waibel 07 Aug '03

07 Aug '03

what are actually the differences between DoC 2000 and DoC Millennium? are both versions working in linux? which one is the newer product? are they electrically (pins, voltage, etc) different? are there any limitation in the size of these chips? i mean -- could a 2GB chip be used on linux? niki

There was some talk about the geode GX1 line here, so I thought people might be interested in the fact that AMD has purchased national's GX1 line, so hopefully in the near future there will be some hardware fixes for the current problems programmers have to deal with.

Preliminary doubts
by John Praveen 07 Aug '03

07 Aug '03

Sorry. I donot know whats the problem. I can get mails properly sent through this id. Hi, I have the custom board (geode sc1200) with peripherals like ethernet, PCI audio video decoder, Tuner, hard disk, SDRAM, Flash memory. I will have to have my BIOS program, linux kernel and specific application program in my Flash memory. I have hard disk only for storing files. My Flash memory is of 32 Mbits and SDRAM 32MBytes. I want to use LinuxBios. I build it for nano mainboard. But still I have many doubts. In normal BIOS, we will say the bios program to load the bootloader from hard disk into location 0000:7C00. What part of the program in Linuxbios will bring my linux kernel image from Flash into SDRAM? Is any options or something to be included in the configuration file to say to boot from Flash memory. In my embedded device the Flash memory is mapped to physical address 00000h to 3FFFFFh. So at what location should i place the linuxbios romimage and linux kernel image in my Flash memory? Where shall my application program be placed in Flash? I hope I should have a filesystem. Is the MTD meant for the filesystem? What part of the program in Linuxbios will bring my linux kernel image from Flash into SDRAM? Thanks in advance. Regards, John. --------------------------------- Do you Yahoo!? Yahoo!

It seems the Kernel clear 0x0--4k. Of course after itself take the MP TABLE. Maybe need to update the kernel.

Under 6G RAM linuxbios_tables occupy 0x500-0xaf4, cmos_util can find option_table after power on but can not find it after rebooting. The only difference should be that rebooting don't execute auto.c again. Any advise.

So you will add one module that will produce PIRQ automatically?
