[U-Boot-Users] reading environment from flash fails
by Wolter Kamphuis 01 Dec '03

01 Dec '03

Hi all, I need some help converting a patch for ppcboot-1.1.6 to u-boot. I've got the following patch for ppcoot-1.1.6: http://wkamphuis.student.utwente.nl/u-boot/ppcboot-1_1_6_qs.patch This patch is for the QSLinux QST23/QS850/QS860T boards. See http://www.snmc.com/prod_qs850.html The patch is made by Daris Nevil (SNMC), it works fine but hasn't been ported to u-boot yet, it's also very large (+500k). The past few days I've been busy porting this patch to u-boot, version 1.0.0. While porting I've run into a problem. Saving the environment to flash ('saveenv') works but this environment isn't read when rebooting. I can't figure out why. Our board has 8Mb flash, mapped to ff800000. Here's the layout: ff800000 to ffee0000: root filesystem ffee0000 to ff000000: readwrite ext2 filesystem fff00000 to fff20000: u-boot fff20000 to ffffffff: linux kernel We define: #define CFG_MONITOR_BASE 0xFFF00000 #define CFG_ENV_SECT_SIZE (128*1024) #define CFG_ENV_SIZE (2*1024) #define CFG_ENV_ADDR (CFG_MONITOR_BASE + CFG_ENV_SECT_SIZE - CFG_ENV_SIZE) So the environment is located at fff1f800. I've added some debugging into the source, which results in: file console.c, func console_init_f, line 368 CFG_ENV_ADDR = 'fff1f800' gd->env_addr = 'fff08174' Memory location fff1f800 contains nothing, but after a 'saveenv' my environment is saved there. Memory location fff08174 contains my default environment and is unchanged after a 'saveenv'. Shouldn't gd->env_addr be equal to CFG_ENV_ADDR? Now my saved environment settings aren't read and after a reset all settings are restored to the defaults. The original patch, my unfinished patch and some screendumps are available on my website: http://wkamphuis.student.utwente.nl/u-boot/ Could someone give me a tip pointer where to look for a solution? I have a feeling it has something to do with the u-boot.lds file but I don't know what. thanks in advance, Wolter Kamphuis, MuLogic B.V.

M5272C3 is ok concerning licensing/copyrights. As discussed before, this means I will not be able to merge your work into the public U-Boot source tree.

[U-Boot-Users] Little endian
by Ed Okerson 28 Nov '03

28 Nov '03

How much testing has been done on little-endian mode of u-boot? Does everyone pretty much just use big-endian, or is there a mix? I am working on getting the Compact Flash to work properly on the Au1500, and I know there is some weirdness with this particular chip, but I just wondered if anyone else has similar problems in little-endian mode. I noticed that there was special handling done in common/cmd_ide.c for input_swap_data(), but not for input_data(). It would seem to me that if one of them was in the wrong endian mode, the other other would be as well, or did I miss the point? Same thing for input_data_short()? And if they bytes need to be swapped in the input routines, don't they need to be swapped on the output routines as well? Does all of this only need to be done for the AU1X00 series processors?

[U-Boot-Users] [PATCH] bootretry enviroment variable
by Pavel Bartusek 27 Nov '03

27 Nov '03

Hi, paste from the doc/README.autoboot CONFIG_BOOT_RETRY_TIME CONFIG_BOOT_RETRY_MIN bootretry environment variable These options determine what happens after autoboot is stopped and U-Boot is waiting for commands. CONFIG_BOOT_RETRY_TIME must be defined to enable the boot retry feature. If the environment variable 'bootretry' is found then its value is used, otherwise the retry timeout is CONFIG_BOOT_RETRY_TIME. CONFIG_BOOT_RETRY_MIN is optional and defaults to CONFIG_BOOT_RETRY_TIME. All times are in seconds. If the retry timeout is negative, the U-Boot command prompt never times out. Otherwise it is forced to be at least CONFIG_BOOT_RETRY_MIN seconds. If no valid U-Boot command is entered before the specified time the boot delay sequence is restarted. Each command that U-Boot executes restarts the timeout. end of paste from the doc/README.autoboot Currently is used function simple_strtoul() for parsing the bootretry enviroment variable. It fails if the bootretry is negative. The attached patch should fix it. -- Pavel Bartusek <pba(a)sysgo.com> Software Engineering SYSGO Real-Time Solutions AG | Embedded and Real-Time Software Lise-Meitner-Str.15 89081 Ulm, Germany Voice: +49-731-9533-1295 FAX: +49-731-94683-10 www.sysgo.com | www.elinos.com | www.osek.de --- u-boot.ori/common/main.c Thu Nov 27 19:25:30 2003 +++ u-boot/common/main.c Thu Nov 27 19:26:03 2003 @@ -505,7 +505,7 @@ char *s = getenv ("bootretry"); if (s != NULL) - retry_time = (int)simple_strtoul(s, NULL, 10); + retry_time = (int)simple_strtol(s, NULL, 10); else retry_time = CONFIG_BOOT_RETRY_TIME;

[U-Boot-Users] U-Boot code checksum?
by Ted Schmitz 27 Nov '03

27 Nov '03

Does the U-Boot code generate and check a checksum or CRC on itself? I see code to verify CRC checksums on images that U-Boot loads into memory, but I do not see any code that checks the U-Boot image itself. If there is a function that checks the U-Boot CRC or checksum, could someone point it out to me? We burn the U-Boot code into a boot PROM and I need some way of verifying the boot PROM was burned correctly when the system powers up. I've written checksum generation and verification utilities in the past but would prefer to use the utilities that come with U-Boot if they exist.

[U-Boot-Users] Debugging U-Boot on 440GP
by Brian Padalino 27 Nov '03

27 Nov '03

I have a BDI2000 and a custom target board. I am can successfully connect to it and step through single instructions. I can also set a breakpoint at _start_440, but any breakpoints after that do not get noticed. I have the BDI setup for HARD breakpoints. Should I have it setup for SOFT instead? What I am seeing is that when I stop the CPU, it's either at 0x700 or 0x1400 -- both of which are defined in the kgdb.c file, but I don't know what they mean. Can anyone shed any light on the situation for me? I am very new to both the BDI and using gdb (but I learn quickly). Thank you, and much is appreciated. Brian Padalino

[U-Boot-Users] Standalone application problem
by Srikanth Sherman 25 Nov '03

25 Nov '03

Hello, I have an Ebony 440GP development board and as a test, I'm trying to run the hello_world application from the flash. I can run the application without any problems from the SDRAM (ie, "tftpboot 0x40000 hello_world.bin" and then run "go 0x40004"). However, I would like to burn the application into the onboard flash and execute it on powerup. If I copy the .bin to 0xff800000 and then set my bootcmd to "go 0xff80000" everything seems to work OK until I leave the board off for a while in which case the application displays garbage on the screen after U-Boot starts it. There appears to be a problem with some data in 0x40000 load area that isn't there when I power off the board and power it back on. I've also tried converting the hello_world ELF to an .img by using /tools/mkimage and that causes the application to hang right after U-Boot passes control to it. Also, running "bootelf 0x40000" after "tftpboot 0x40000 hello_world" causes an exception. So, in summary: How do I load a stand-alone application .bin onto flash after loading it into RAM? Secondly, how do I load and run "hello_world" (ELF) correctly? I know I'm missing something really basic here! Thanks.

I have the BDI setup for HARD > breakpoints. Should I have it setup for SOFT instead? The debug control/status registers need to be setup. By default the startup code in cpu/ppc4xx/start.S clears the dbcr registers, so debug events are disable. The hw debuggers I've used need an event to establish control. If CFG_INIT_DBCR is defined, the dbcr0 is setup with the macro value (see start.S). To set the macro you can do one of the following: Define CFG_INIT_DBCR in your config header to the value you need. Or, if you copied board/ebony/config.mk for your custom board you can simply: $ touch cpu/ppc4xx/start.S $ make dbcr=1 This defines CFG_INIT_DBCR=0x8cff0000 -- which should give you all events. > What I am seeing is that when I stop the CPU, it's either at 0x700 > or 0x1400 -- both of which are defined in the kgdb.c file, but I don't > know what they mean.

[U-Boot-Users] u-boot on the BDAu1500
by Ed Okerson 24 Nov '03

24 Nov '03

I am having a difficult time getting u-boot to run on the BDAu1500 board from AMD. It appears that there is something missing in the board initialization, but I have not been able to track down what it is. If I start the board with yamon in flash, I can successfully load a u-boot image built to run from ram and run it. If I load u-boot into the flash, built with TEXT_BASE set to 0xbfc00000, which is where the board is supposed to start from in flash, it will not init and run from a power on. I tried following the directions at: http://www.denx.de/twiki/bin/view/DULG/DebuggingUBoot to debug the problem, but it appears that the function cpu_init_f does not exist for mips targets. Are there any C functions before relocation for mips targets? Are there any instructions similar to those in the above web page for mips target debugging? Ed Okerson

[U-Boot-Users] SII IDE and u-boot on MPC8540?
by John Clemens 24 Nov '03

24 Nov '03

This is along shot, I know, but I'm running out of ideas so I figured i'd ask anyway.. So, my questions: - has u-boot IDE ever been made to work with MMAP'd registers? - how does one put a pci ide card into native pci mode, when the prog-if bits don't appear to be correct? - does anyone have any experience doing something similar, or is everyone just using an isa bridge and legacy ports? - please tell me i'm missing something obvious and all walk away in shame :) And now, why i ask.. I'm using an MPC 8540 board and a SII 0680A PCI ide controller.. but I can't get u-boot to talk to the IDE at all... It's almost as if the card is insisting on coming up in "compatability mode" (i.e., listening at ports 0x1f0 and 0x170) instead of "PCI-Native" mode where it should be listening for PCI I/O cycles at PCI BAR0/1. This is a problem because there is no ISA space on this board, just a pci bridge. (that is, if i'm understanding things correctly, which is a big "if" at this point) To make matters worse, the card is one of these cheepo software raid controllers, so it identifies itself as class-code RAID instead of IDE, so I'm not certain if the prog-if bits the ATA spec calls out apply or not (prog-if is all 0, which would mean, via the spec, this chip can't do pci-native mode, which just doesn't make sense.) u-boot maps BAR0-3 at [IO] 0xe8000001, 0xe8000009, 0xe8000011, 0xe8000019. According to the PCI ide controller programming interface document, in pci native mode, these should be the base address of the ATA command blocks and ATA control/dev blocks when the controller is in pci native mode. It also maps BAR5 at [MEM] 0xe0000000. dumping memory at e8000000 reveals nothing interesting (mostly zero). dumping memory at 0xe0000000 does reveal something interesting (it appears to be memory mapped registers, confirmed by the fact the Linux SII driver uses this as its mmio space)), but trying several offsets there has led me nowhere. any help, pointers to docs, anything would be greatly appreciated.. thanks in advance. john.c -- John Clemens http://www.deater.net/john john(a)deater.net ICQ: 7175925, IM: PianoManO8 "I Hate Quotes" -- Samuel L.

RE: [U-Boot-Users] booting U-Boot from dBug?

Hi, As Wolfgang Denx has pointed out you can use the low boot option when building. Put the binary image on your tftp server and set up dBUG to download the u-boot binary image through tftp with the dn command. Then use the dBug fp command to burn the image to low boot flash An example for a 16Mbyte MPC5200 Lite card: fp FF000000 FF035250 20000 where "FF035250" will have to be adjusted for your image size. "20000" is where the image ends up in RAM after tftp download. I had problems using tftp at 100Mbps but these problems vanished when I put a 10 Mbps hub between the 5200lite and the rest of the net, forcing the ethernet to 10 Mbps, half duplex.

[U-Boot-Users] booting U-Boot from dBug?

Howdy all, Is there a way to load U-Boot from another bootloader? I would like to be able to load a development version of U-Boot from the Motorola dBug on my MPC5200 board. Thanks, - dan _________________________________________________________________ Groove on the latest from the hot new rock groups!
