[U-Boot-Users] MPPC8560ADS and U-Boot 1.1.1 problems ?
by Rob Farmer 28 Jun '04

28 Jun '04

Greetings, We trying to install the latest version of U-Boot 1.1.1 on a MPPC 8560ADS development board, this initially does not boot (it actually sits inside in a permanent loop after the first couple of instructions). We have a Abatron debugger with a GDB/DDD interface but we don't seem to be able to step through the code to understand why it doesn't work. We built U-Boot with the correct settings for the board, I believe that the dev board we're using is one of the support variants. Are there any known problems with 1.1.1 and the 8560ADS boards ? Any help that any one could give would be extremely useful.

[U-Boot-Users] nomen est omen: i.MX or mc9329 ?
by Steven Scholz 28 Jun '04

28 Jun '04

Hi there, how will we call the Motorola i.MX processors in future? Will it be "imx", "i.MX", "iMX" or MC9328MX{1,21,L}? Should we call the eval board "mx1ads" oder "M93281ADS" as Motorola does and as it is printed on it? How are the plans for linux-2.6 port? We should keep it consistent... Thanks a million! Steven

[U-Boot-Users] MPC5200: Moving SDRAM init out of board scope
by Jonas Mark-r50740 28 Jun '04

28 Jun '04

Hello, I am currently porting U-Boot to a new MPC5200 platform (Total5200). To reduce code duplication I would like to move the Lite5200 / IceCube SDRAM initialization (sdram_start() and initdram()) from board/icecube/icecube.c to cpu/mpc5xxx/sdram.c. So two platforms would use the same code base. Any objections? It seems that at least the maintainer of the PM520 board could change his code rather quickly to use this scheme as well. Regards Mark

[U-Boot-Users] u-boot and 2.4.18 kernel problem
by Lokesh Kumar 25 Jun '04

25 Jun '04

I am using u-boot-1.0 and 2.4.18 with my 855T custom board. u-boot loads the kernel from flash. Sometimes, u-boot says "uncomressing image .. OK" and then nothing happens. I have to reset the power to the board to get it working. My board runs at 49.152 MHz and has 16MB flash and 32 MB SDRAM. I have checked my SDRAM UPMA settings and cannot find anything wrong with it. Any help? Lokesh Kumar Wireless Matrix USA Inc. 703-262-4032

[U-Boot-Users] U-BOOT FOR MPC8272ADS - network issue
by Stan Kuciej 25 Jun '04

25 Jun '04

Hi Everyone, I'm using u-boot on a MPC8272ADS board and I'm experiencing the following behavior - From a cold start u-boot starts up and downloads my OS via bootp fine. Whenever the MPC8272ADS is reset in any way other than cycling the power the network software doesn't seem to receive any packets. The MPC8272ADS is able to ping other hosts but it won't answer any pings from the other hosts. Has anyone seen this behavior? Thanks, Stan Kuciej

There was some mailing list email a while back from a guy asking about U-Boot for a board a lot like the Wind River wrSbc8240 board. I did a quick and dirty 'port' of the CU824 board files and now have a diff patch about ready to submit. I see that for some of the boards (cu824) the README file includes the 'U-Boot test results'. Is there a formal checkout suite or any kind of validation test set?

[U-Boot-Users] u-boot hangs right at beginning
by Glenson Muthedan 25 Jun '04

25 Jun '04

Hello! I had U-Boot-0.4.0 running on my custom board(based on PXA250) quite good. But I've troubles to get U-Boot-1.1.1 running. It hangs very early in the bootloading procedure: before relocation and before any console output. Trying to debug with GDB and BDI2000, I get the following response from the board. Especially the address "0x50000000 in setup_end_tag", the value "bd=0x40000000" and the message about exceeding line numbers are quite confusing for me. Can somebody give me atleast a hint, which config-options are related to this. Thank you very much in advance.

[U-Boot-Users] u-boot on a dbau1000
by Othmar Pasteka 25 Jun '04

25 Jun '04

hello, I just tried to load a compiled u-boot image on a dbau1000 devel board. but as it seems that quite at the beginning of loading the image via tftp the whole system froze. accidentally I also did this with the other boot rom, so prolly both are busted. the number display on the board shows a "02" whatever that means. I couldn't find documentation what this should actually mean. I assume that it means, more or less, that I busted the system. is there anything I can do right now to resurrect the boot rom, like resetting it to factory defaults, whatsoever? or more or less the last option I have is to call AMD? the other technical question I'ld like to get some enlightenment is, why the system freezes or like, why is the boot rom busted just when doing a load? is load doing more than just moving the image into the ram? which is so far my understanding what load does. maybe I omitted something in the docs ... any hints, answers are greatly appreciated :). the u-boot version in question is 1.1.1 but I had to made some changes to the source so that it compiles, like finding functions in start.S and the like. I wonder if the setup as it is shipped in 1.1.1 and cvs is supposed to work or how much hacking should be put in there that it is compileable. regards, Othmar

[U-Boot-Users] Where is flash_init() after u-boot relocated to RAM?
by Shawn 25 Jun '04

25 Jun '04

Hi, I'm trying to trace into flash_init(). The function is called after u-boot is relocated to RAM. So the System.map is no longer useful. How can I know the address of the function to set a breakpoint? The following screenshot shows that u-boot locates at 0x07fd9000. I tried to get the address by adding the offset got from System.map to 0x07fd9000. But it seems not right because GDB didn't stop at that address.

[U-Boot-Users] flash.c for various boards
by gold ares 24 Jun '04

24 Jun '04

Dear Wolfgang There is a flash.c in every board directory in the sourcetree.But some are almost the same. I think we should not do it with this style. But I feel the RTC is a clear style. We should write the different flash.c for various flash chips but not for various boards. Do you think so?? A clear source tree directory can make users understand the code quickly. Thanks a lot. goldares -- _____________________________________________________________ Web-based SMS services available at http://www.operamail.com. >From your mailbox to local or overseas cell phones.

Hi Alex, I reply to mailing because your address is unreachable from me. The evaluation board TB0229 has NEC's VR4131 as CPU. The PCI bridge is build in. So I think you should read the CPU's manual instead of TB0229's manual. Please read the chapter 17 of the following manual. http://www.necelam.com/docs/files/U15350EJ2V0UM00.pdf Best regards.

[U-Boot-Users] TEXT_BASE question
by Frank Young 23 Jun '04

23 Jun '04

Hi, I am trying to install u-boot on my walnut board with PPC405. In file board/walnut405/config.mk, TEXT_BASE is defined as FFFE0000. Does that mean the u-boot.bin has to start from FFFE0000? My problem is that on my board the address space from FFF80000 to FFFFFFFF is reserved for a special purpose, so I can't put the u-boot.bin at FFFE0000. But if I change the TEXT_BASE to another one, for example FFF00000, then the u-boot.bin generated by the compiler is FFFFFFFF - FFF00000 = 1MB. It means I still can't put the u-boot.bin to FFF00000 because it will overwrite the reserved address space anyway. I understand that u-boot is trying to fill the gap between TEXT_BASE and the end of the flash. So my question is: 1. If I use TEXT_BASE = FFFE0000 and simply put the u-boot.bin generated to FFF00000, will it mess up the addressing in the u-boot? 2. If the answer for 1 is yes, how can I move up the end of flash to FFF80000 so that the u-boot.bin will fill from FFF00000 to FFF80000 instead of from FFF00000 to FFFFFFFF?

[U-Boot-Users] u-boot on top of another bootloader
by Shawn Jin 23 Jun '04

23 Jun '04

Hi, Can u-boot run on top of another bootloader? The board I'm working on has a proprietary boot loader. I cannot totally abandon this bootloader because the vendor is unwilling to disclose some critical details of the board. So I'm thinking of putting u-boot on top of it. Is this idea feasible? The original boot loader is at 0xFFF00000. One thing I need to do is to move the u-boot location to somewhere else. AFAIK u-boot usually locates at 0xFFF00000. What feature of a board decides the address of the first instruction? Thanks, -Shawn. __________________________________ Do you Yahoo!? New and Improved Yahoo!

[U-Boot-Users] redundant environment block
by David Ho 23 Jun '04

23 Jun '04

Hi all, As I understand it, the ENV_REDUND feature in u-boot protect the environment in flash from a power failure during saveenv. It appears it will not protect it against accidental scribbling from errant code/processor. I like to know from the community, whether it is important to protect it against flash scribbling, or are the majority of flash environment corruption due to interruption to the saveenv command? Thanks a lot, David
