RE: Irq_table not loaded when boot from etherboot
by Lawrence LL. Dai 22 Jan '03

22 Jan '03

Hi, I have dumped the two files from my system, but I still have several puzzles: 1. How can replace the "conforms" with "MP_IRQ_TRIGGER_EDGE|MP_IRQ_POLARITY_HIGH" in the mptable.c? Should I ask the hardware Engineer for help? 2. Shall I change following strings in mptable.c to instruction as "smp_write_intsrc(mc, mp_NMI, conforms|conforms, 0x0, 0x0, MP_APIC_ALL, 0x1)" ? If should, how can I do this? MP Config Extended Table Entries: -- System Address Space bus ID: 0 address type: I/O address address base: 0xc000 address range: 0x3000 Could you help me to check the files attached? Please teach me how to fix them. Best Regards, Lawrence -----Original Message----- From: Ronald G. Minnich [mailto:rminnich@lanl.gov] Sent: 2003?1?17? 23:06 To: Lawrence LL.

warm reboot Geode
by John Allen 17 Jan '03

17 Jan '03

When I use the reboot command on my Dorado demo board from National (with their BIOS), It will successfully warm boot the machine. When I use my LinuxBIOS image on the Dorado or my Geode machine, the machine just stalls at the point where the reset should occur. It seems to me that Linux is performing a BIOS Int function that is not implemented in my build of LinuxBIOS. Anyone had any luck with this? John

Hi All: I have tried to boot from network with linuxbios and failed. The output showed: "PCI: No IRQ known for interrupt pin A of device 04:01.0. Probably buggy MP table" Will the irq_table only be loaded in hardwaremain() which is not called in etherboot? Who can give me some help? Thanks. Ps: the attached is the output. Best wishes, Lawrence

DDR SDRAM Initialization.
by sivakumar 17 Jan '03

17 Jan '03

Hi, I want to support DDR SDRAM in linuxbios. When was browsing the code, I found only the SDRAM support. Also I found from the specification that Initialization sequence of DDR SDRAM and SDRAM are different. Have any one coded for initialization of DDR SDRAM. Currently I am writing the code to support the DDR SDRAM using DDR SDRAM spec. I am facing some problem with that. Can any send me the DDR SDRAM initialization sample code for reference , if you have? Thanks, Siva.S -- sivakumar <sivakumar.subramani(a)wipro.com> wipro

rom image dates
by John Allen 16 Jan '03

16 Jan '03

I noticed that the romimage files created by the linuxBIOS build do not have a date in the last few bytes of the image. I believe that most rom images use this area to identify the date the rom was compiled. Is there a tool in the LinuxBIOS "arsenal" that can add the date to the correct file, say linuxbios.rom, before performing the cat to get romimage? John

Jumping to LinuxBIOS
by sivakumar 16 Jan '03

16 Jan '03

Hi, My image boots up to the following serial output message, Ram5 Ram6 Copying LinuxBIOS to ram. Jumping to LinuxBIOS. It says that it is jumpimg to LinuxBIOS, that means it has copied the images to RAM. So next step is to CALL(harwaremain). It is not jumping in to hardwaremain function. >From the linuxbios.map I found that address of hardwaremain function is 00000904 T hardwaremain I have checked my DDR SDRAM register programming and initialization progams with specification. It looks ok to me. If you want I can send it for reference. I want to verify that following option that I am using are correct are not, Some configuration I am using are as follow, I am not currently enabling MTRR. Currently I am look with the performance. I am not supporting SMP now. I also verified some of the DDR SDRAM register by read it back. I am using 256 KB Flash ROM and 256 MB RAM. While burning the Flash I am burning the 65 KB linuxbios.strip file on FLASH ROM. I have attached the makefile.settings along with this mail. Can any one help me in resolving the problem ;-( -Siva -- sivakumar <sivakumar.subramani(a)wipro.com> wipro
