[U-Boot-Users] BDI2000-virgin board
by Ted Hill 23 Jun '05

23 Jun '05

Hi, I need a help with BDI2000(MPC8266) --which i think almost everyone here use--, can BDI2000 treat with a virgin board? a not erased Flash? assume a flash all programmed with zero , so all the first 256 bytes of flash are zero , and if cpu reads these configuration bytes it will be set incorrectly, is such flash programable by BDI2000? (We developed a custom board. My flash should get FF for all bytes if erased. , I have a BDIPro and when I dump the flash, it's all zero ,it could not be erased nor programmed. what could I do, and what's my problem?) Best regards, Ted. --------------------------------- Do you Yahoo!? Yahoo! Mail - You care about security. So do we.

[U-Boot-Users] Jump location
by Ricky 23 Jun '05

23 Jun '05

Hi List, I have a confusion with Jump address. In case of MPC processor, I have reset vector at 0xffffffc which is mention is "board/<board_name>/u-boot.lds" script file. If we edit the binary file we used to get Jump instruction ..in my case its "4b ff f0 04" what exactly it means how it will jump to the location FFFFF000...I have seen this address in u-boot.lds script file. Can anyone put some commnet on this.

[U-Boot-Users] u-boot r1 machine type value to AT91RM9200 2.6.12 kernel
by Dikhoff＠gmx.de 23 Jun '05

23 Jun '05

Hello, I tried to use the linux 2.6.12 release for AT91RM9200, but when I started with u-boot 1.1.2 the Kernel stopped. I can configure a working kernel with the option 'config NAKED_Boot= y ', but with this option it's not possible to pass any bootarguments to the kernel. How can I pass the corret R1 value for the machine type ('0xfb') from u-boot 1.1.2 to the kernel? The last working kernel in combination with u-boot was 2.6.12rc4. What changes in the u-boot source do I have to maintain relating to these boot options? Or is it possible to pass the r1 value in between the 'bootargs' of the u-boot enviroment? Any help would be appreciated Regards Sascha -- Weitersagen: GMX DSL-Flatrates mit Tempo-Garantie! Ab 4,99 Euro/Monat: http://www.gmx.net/de/go/dsl

[U-Boot-Users] Question about MPC8272 HRCW
by raymond yang 22 Jun '05

22 Jun '05

Hello, I am confused about the followin fields in HRCW, MPC8272 CIP - 0 MSR[IP]=1 (default), Exceptions are vectored to the physical address 0xfffn_nnnn 1 MSR[IP]=0, Exceptions are vectored to the physical address 0x000n_nnnn BMS - Boot memory space. Defines the initial value for BR0[BA]. There are two possible bootmemory regions, HIMEM and LOMEM 0 0xFE00_0000 -- 0xFFFF_FFFF 1 0x0000_0000 -- 0x1FFF_FFFF My question: 1) Given BMS = 0 Does this mean, the FLASH(on CS0) are given the base address as 0xFE00_0000? 2) Given CIP = 0 Does this meman, the vector should be placed at 0xFFFn_nnnn? So With BMS=0, and CIP=0, my flash should be bigger than 0xFFFn_nnnn - 0xFE00_00000 >16M, right? 3) Given my flash is 8M byte, 16bit-bus-width, is it a valid HRCW word for 08_82_32_45 My image got the following configurations MONITOR_BASE=TEXT_ADDR=0xFFF00000 CFG_FLASH_BASE = 0XFE800000 I tried many times, with BDI plugged, u-boot works fine. However, without BDI and RSTCN pull-up, looks like the image never got run. Any ideas? Thanks ahead. Best Regards Raymond __________________________________________________ Do You Yahoo!?

[U-Boot-Users] linux kernel boot hangs with CONFIG_CMDLINE_TAG defined
by Tehn-Yit Chin 22 Jun '05

22 Jun '05

Hi all, I have strange problem with passing the boot arguments to the linux kernel on bootup. I have read the following entry at www.denx.de but am unable to come up with a suitable solution. http://www.denx.de/twiki/bin/view/DULG/LinuxKernelIgnoresMyBootargs I am booting a 2.6.11 kernel on a Samsung S3C2410 custom board. If I don't have CONFIG_CMDLINE_TAG defined in my platform specific header file, the kernel boots up fine as it grabs the default boot arguments from itself. If I have CONFIG_CMDLINE_TAG defined, the last message I see on the console is the "Starting Kernel" message. I have also tried the other CONFIG_SETUP_MEMORY_TAGS and CONFIG_INITRD_TAG as well and they did not improve the situation at all. Any pointers would be great. Many thanks.

Hi all, I am porting the uboot and i want to get rid of the network component at this moment, there is a function cs8900_get_enetaddr () at the start_armboot() of lib_arm/board.c (my program often hangs inside), i have set in my board/xxx.c that #undef CONFIG_DRIVER_CS8900 but after all many error from net/net.c occur . I there therefore set : #define CONFIG_COMMANDS \ ( & ~CFG_CMD_NET \ ) in order to get rid of the comilation of the network part, but the compiler keep on compiling the network part and many errors occur, do anyone know how to solve this problem ?

The Configuration registers of the CF card are: Configuration Option register (200H): 0x01 Configuration and Status register (202H): 0x80 Pin Replacement register (204H): 0x2e Socket and Copy register (206H): 0x00 I tried different INDEXes in Configuration Option register, but the result is still the same. I can not find out, what I can not access the task file registers. I would appreciate any hint.

[U-Boot-Users] No taskfile registers for PCMCIA IDE ?

Hi all, I am working with PXA255 board (~Cerfboard) and I am trying to access PCMCIA CF via IDE. But it goes like this: 1. power PCMCIA - OK 2. get CIS information - OK 3. access CF's Configuration registers - OK 4. access Task File Registers - FAIL: task file registers seem not to be present anywhere (!?) Can anybody give me a hint, what do I miss? Thanks in advance, Jakub Václavík
