by Nicolas Colombain 30 Jun '05

30 Jun '05

Hi Ilandre and Kurt, I need to download my Spartan 3 by using uboot and I was wondering if someone had already written something for that. I found your mails but unfortunately not the patch. :( This patch will be added to the next uboot version ?? Where can I find it ? Thanks in advance.

[U-Boot-Users] [PATCH] append to ALL var instead of assigning
by Murray.Jensen＠csiro.au 30 Jun '05

30 Jun '05

This patch appends values to the ALL make variable, rather than assigning them, so that earlier included make fragments can put values into it without them being overwritten. Cheers!

[U-Boot-Users] about use mkimage to create uImage?
by zhuzhenhua 30 Jun '05

30 Jun '05

if i mkimage without compressing, kernel can run correct, the command is as follow ./tools/mkimage -A arm -O linux -T kernel -C none-a 0x30000000 -e0x30008000 -n "Linux" -d vmlinux uImage but i want to create a compressed uImage,i use commands like these,it stop at "starting kernel..." arm-linux-objcopy -O binary -R.note -R.comment -S vmlinux linux.bin gzip -9 linux.bin ./tools/mkimage -A arm -O linux -T kernel -C gzip -a 0x30008000 -e0x30008000 -n "Linux" -d linux.bin.gz uImage i think the second method should run well,and i see the same example in the Readme of u-boot src. any hints are appreciate.

[U-Boot-Users] silent console, nulldev and CONFIG_AUTOBOOT_KEYED
by Ladislav Michl 29 Jun '05

29 Jun '05

Hi, If "silent" env variable is set GD_FLG_SILENT is added to gd->flags (in console_init_f). That effectively causes all console output to be suppresed. That flag also causes nulldev to become outputdev (in console_init_r). Btw, shouldn't CONFIG_SILENT_CONSOLE depend on CFG_DEVICE_NULLDEV in this case? Now we are entering into abortboot (CONFIG_AUTOBOOT_KEYED) and because "silent" env variable is set and also CONFIG_SILENT_CONSOLE defined console_assign (stdout, "serial"); is called, doing basicaly nothing, because GD_FLG_SILENT which is still set prevents any console output. There are various solutions from this situation, but I'd like first understand what is CFG_DEVICE_NULLDEV good for when we have GD_FLG_SILENT? Or better, how should all these three things in question behave? thanks, ladis

[U-Boot-Users] Linking problem on new port
by Richard Danter 29 Jun '05

29 Jun '05

Hi all, I have been using U-Boot for a while, but this is the first time I have tried to port it to a new board myself, so please consider me a newbie! I have a problem linking U-Boot for my new board. I know this is my fault, I have missed something in the setup, can anyone point out what it is that is missed? The compile stage works, this is what I see when I try to link: ---- ppc_74xx-ld -Bstatic -T /usr/home/wb231-le11/Workspace/u-boot/board/ppmc7xx/u-boot.lds -Ttext -n $UNDEF_SYM cpu/74xx_7xx/start.o \ --start-group lib_generic/libgeneric.a board/ppmc7xx/libppmc7xx.a cpu/74xx_7xx/lib74xx_7xx.a lib_ppc/libppc.a fs/cramfs/libcramfs.a fs/fat/libfat.a fs/fdos/libfdos.a fs/jffs2/libjffs2.a fs/reiserfs/libreiserfs.a fs/ext2/libext2fs.a net/libnet.a disk/libdisk.a rtc/librtc.a dtt/libdtt.a drivers/libdrivers.a drivers/sk98lin/libsk98lin.a post/libpost.a post/cpu/libcpu.a common/libcommon.a --end-group -L /opt/eldk3.1.1/usr/bin/../lib/gcc-lib/ppc-linux/3.3.3/m7400/pic -lgcc \ -Map u-boot.map -o u-boot ppc_74xx-ld: invalid hex number `-n' ---- The $UNDEF_SYM is obviously wrong (I think!). I am not surprised if I have missed things, so far I have written just a skeleton for the board support, even if it links it won't run yet. I have been adding things as needed, but I just can't find what is missing here. Any suggestions? I'd like to ask another question too whilst I'm here. I have a single bank of Flash running from 0xFFC00000 to 0xFFFFFFFF. I want U-Boot to be placed at 0xFFF00000 with the entry point at 0xFFF00100. Am I right to set the following? If not, how do I achieve this? #define CFG_FLASH_BASE 0xFFC00000 #define CFG_MONITOR_BASE 0xFFF00000 Is this related to the problem above? Many thanks! Rich

[U-Boot-Users] where is the EP8248 patch?
by Nishant Galange 29 Jun '05

29 Jun '05

Hi Yuli On 12 Dec 2004, You posted a patch for the Embedded Planet EP8248 board. How do I download this patch? Is it already included in u-boot 1.1.2? Once I have all the necessary source code (with the patch incorporated), what command(s) do I give to compile u-boot 1.1.2 for the EP8248 board? Will the following work: $ export CROSS_COMPILE=ppc_82xx- $ export PATH=[path_to_ELDK]:$PATH $ make EP8248_config $ make Waiting, Nishant

[U-Boot-Users] Help! Low-16 bits of SDRAM can not work!
by zhao haijian 29 Jun '05

29 Jun '05

Hi,All I have been working on such a board we made: *************************************** CPU: PXA255A Flash: Intel StrataFlash 16MB x 2 SDRAM: Samsung K4S5616320 32MB x 2 Two 16bits SDRAM chips are connected by the same CE,OE,OW,ADDRESS signals,forming a 32bits-width memory structure. *************************************** Using a emulator,I see the high 16bits of sdram works well,while the low 16bits always fail,though I've try many combination of configuration. We also found no problem with the hardware by an oscilloscope. I want to know what could lead to this? (Maybe a FATAL bit in a mysterious configuration register?) Anybody ever met this? BTW,I work on the base of CERF250 board. Best Regards, Phililp Beijing P.R.China

[U-Boot-Users] Strange : Same 8248 image needs to be reprogrammed
by Sam Song 28 Jun '05

28 Jun '05

Hi all, After porting u-boot on a 8248 board, I was confused by a programming problem with WireTAP. For the sake of 8248/8260 HRCW theory, RSTCONF must pull up to connect 8248 target with a No-head config file when there is a blank FLASH on board or WireTAP cannot init the target correctly. The programming process is as follows: Pull up RSTCONF -> Connect WireTAP with No-head config file -> Program the image on 0xff000000 -> Disconnect WireTAP -> Pull down RSTCONF -> Power-on -> No serial output -> Power-down -> Connect WireTAP with head config file -> Reprogram the same image at 0xff000000 -> Disconnect WireTAP -> Power-on -> Work! We suspected sth wrong on first programmig. So we checked the FLASH content with WireTAP but found at least first and last three bytes had the right content. Should I need to check all FLASH content? The image I compiled first is about 100KByte!!! I wanna to blame it on config file we used or FLASH programming mechanism or 8248 itself. But I have no clear clue with them:-( Could anyone have similar experience on 8260 series target? How about BDI2000 on it? Any idea?

[U-Boot-Users] Q: how about "closed" hardware platforms?
by Leif Lindholm 28 Jun '05

28 Jun '05

Hi Like I mentioned in my previous mail to the list, I no longer have access to a db1550 board, so I can no longer test/verify au1550 support. We use u-boot in our mood 100 and 300 set-top boxes, which are only sold to network operators and the like. Where I'm getting at is - would it be possible to get our u-boot patches integrated into mainstream CVS (or git?), even though probably noone outside this company will ever be actively using u-boot on these boards? / Leif

[U-Boot-Users] invalid option 'short-load-bytes'

Greetings! I am trying to cross-compile u-boot-1.1.2 for ARM Versatile Board ARM926EJ-S using cross-toolchain 3.4.2. I am getting the following error: cc1: error: invalid option 'short-load-bytes' cc1: error: invalid option 'apcs-32' It compiles fine with cross-toolchain 2.95.3. Any suggestions? Since it is mentioned here, http://www.arm.com/linux/prebuilt_download.html, that 3.4.2 has been used to compile u-boot, we would like to use the same for cross-compilation. Also, the ethernet is not enabled or detected on power up on this board. I have compiled in support for the SMC ethernet in u-boot-1.1.1, but, u-boot doesn't seem to be able to detect it. I'd appreciate any suggestions for the above.

[U-Boot-Users] [Newbie] MPC8280 FCC internal loopback test
by Srivatsan CR 27 Jun '05

27 Jun '05

Dear all, We are having a MPC8280 based Rattler board with ethernet configured on FCC1. We are writing some POST tests for the board. For Ethernet we thought of running an internal loopback test. We took the eth_loopback_test() in ether_fcc.c as the template and did the necessary modification(s) majorly it was to change the mode register. We are able to see that the initialization of FCC1 is happening properly. But the result printed always says that the transmitted packet is 0 and received packet is 0. Is there something we are missing ? Expecting your help. With Thanks and Best Regards, C.R.Srivatsan
