by Kiran Jammula 23 May '12

23 May '12

Hi, I am using U boot for my project. I need to configure the console while booting by prompting the user from target board LCD and Keypad. So please let me know which file of the U-boot I have to modify to achieve this.

[U-Boot-Users] Ethernet loopback command
by Thomas Schäfer 17 Apr '12

17 Apr '12

Hi, The patch attached provides a command called 'ethloop' which allows to perform loopback testing on the current eth device. To achieve this, a new ethernet packet type (PROT_TEST, 0x0808, AFAIK this is not used otherwise) is introduced in net/net.c. The patch is against SF CVS from 20050307. The functions EthLoopStart, EthLoopSend and EthLoopHandler generate a simple ethernet frame with NetOurEther as destination address and packet type PROT_TEST. The looped back package is compared with the original one and a message is displayed. It is necessary to set the ethernet line into loopback mode either by programming the PHY or using a loopback plug. I've tested this on our PPC405 custom board, but it should also work on all other systems because packet generation is independent of the underlying ethernet hardware. Example usage: => mii w 0 0 7100 <-- sets PHY into loopback mode => ethloop Using ppc_405x_eth0 device Got ethernet loopback frame, len=64 loopback test successfully completed => mii w 0 0 8000 <-- PHY reset after test is completed Maybe this is also useful for others..

[U-Boot-Users] Add a new command to U-Boot
by Carlos Filipe Silva 20 May '09

20 May '09

Hi all! I have one doubt. How can I add a new command to U-Boot? Do I have to use only the macro U_BOOT_CMD() like files .../common/cmd_* or do I have to do more things, like defines, etc.? And after this is compliled with no error, if I type help in U-Boot's shell, do I see this command like the others? Best regards, Carlos Silva

[U-Boot-Users] mtdparts
by Ladislav Michl 29 Oct '06

29 Oct '06

Hi there. I'm just trying to sync with U-Boot development and found a little regresion in new mtdparts code. Previously I was using custom partition function, which let me do precisely what I wanted. mtd0 - U-Boot mtd1 - env mtd2 - r_env mtd3 - rootfs0 mtd4 - rootfs1 ... etc In above scheme my custom part function allowed only chpart [34], so it was not even possible to change partition to evn sector for example. Moreover it was pretty easy to construct kernel command line this way: setenv bootargs '$bootargs root=/dev/mtdblock$partition ro rootfstype=jffs2' And everything worked nicely. That is no longer case and it's real pain with both NOR and NAND devices used in system. Prefered solution for me is to fix kernel to be able to mount root filesystem from MTD device given by name (root=mtd:rootfs0) unless someone has better idea :-). Something which would work also with 2.4 kernels would be appreciated. ladis

[U-Boot-Users] MIPS: AMD Alchemy au1x00 ethernet problems
by geoff cleary 23 Jul '06

23 Jul '06

Hi I am seeing a problem with network support on the AMD dbau1550 eval board (and our own board based on Au1550). It seems that after one network command, no further packets can be sent. The minimal case that shows the problem is to include the ping command. The first ping will succeed; any other network commands time out. I have successfully loaded large files using tftpboot command and confirmed the image loaded correctly. Trying the command again fails with TX timeout. Has anyone seen this problem or have any suggestions as to what is going on? We are building little endian. I have tried Joseph Chiu's buffer 0 patch. Thanks Geoff __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

[U-Boot-Users] [Patch] KVME080 Support
by Sangmoon Kim 22 Jul '06

22 Jul '06

Hi, This patch adds support for KVME080 board. KVME080 is a VME board with MPC8245 CPU. It also patches drivers/cfi_flash.c. First, it adds CFG_FLASH_PROTECT_CLEAR because for some flash memories(such as 28F320C3) all banks are protected after reset. Second, it makes write_buff not to call flash_write_cfibuffer if buffer_size is1. Because for flash memories with buffer_size 1, buffer write is not supported. Third, it makes 64 bit writes to use FLASH_WRITE64 if FLASH_WRITE64 is defined. Because KVME080 needs it. Fourth, it makes flash_detect_cfi call FLASH_PORTWIDTH when changing portwidth if FLASH_PORTWIDTH is defined. Because on some CPUs (such as MPC8245), port width should be changed. Regards, Sangmoon Kim

[U-Boot-Users] MIPS LE build problems
by Wolfgang Denk 22 Jul '06

22 Jul '06

Dear Thomas, I always wondered what exactly was the reason why I was not able to build the dbau1x00 targets (especially the little endian dbau1550_el target using the ELDK toolchain). Also, I always wondered about the reference to a non-exitent cpu/mips/little/liblittle.a library. Is ther ea special reason for the current settings of build options for the dbau1x00 targets? Attached below is a patch which makes all dbau1x00 targets build fine with the current ELDK, and I believe these settings are more correct than the previous ones. If you don't protest I would like to merge this patch into the public source tree?

[U-Boot-Users] parse bug in cmd_mii.c
by Andrew Dyer 22 Jul '06

22 Jul '06

I noticed that in do_mii() the code is dereferencing argv[1] without checking what value argc has. This leads to an exception if a command line like 'mii ' is given where argv[1] is NULL. I have a patch, but my cmd_mii.c is carrying around some other patches (some submitted to the list, some local). Is there a good way to separate out the patches I want to submit by themselves? -- Hardware, n.: The parts of a computer system that can be kicked.

[U-Boot-Users] NOTE: New MTD flash partitioning methods
by Wolfgang Denk 20 Jun '06

20 Jun '06

Hello everybody, especially board maintainers! I just comitted a bigger patch that implements a new "mtdparts" command and a common partition scheme that allows U-Boot and Linux to share the same idea about flash partitioning.. Old, obsolete and duplicated code was cleaned up and replaced by the new partitioning method. There are two possible approaches now: The first one is to define a single, static partition: #undef CONFIG_JFFS2_CMDLINE #define CONFIG_JFFS2_DEV "nor0" #define CONFIG_JFFS2_PART_SIZE 0xFFFFFFFF /* use whole device */ #define CONFIG_JFFS2_PART_SIZE 0x00100000 /* use 1MB */ #define CONFIG_JFFS2_PART_OFFSET 0x00000000 The second method is to use the "mtdparts" command line and dynamic partitioning: /* mtdparts command line support */ #define CONFIG_JFFS2_CMDLINE #define MTDIDS_DEFAULT "nor1=zuma-1,nor2=zuma-2" #define MTDPARTS_DEFAULT "mtdparts=zuma-1:-(jffs2),zuma-2:-(user)" Command line of course produces bigger images, and may be inappropriate for some targets, so by default it's off. The code was tested on the following targets: Alaska8220, CPCI4052, NC650, PPChamelion, incaip. Besides the above targets, there were several other targets affected, where necessary changes were made. However, no testing was done for those targets, only compilation was verified (for PPC, MIPS and ARM targets). Due to the lack of tool chain for NICOS and i386 I was not able to compile the following targets: ADNPESC1, DK1C20, DK1S10, sc520_cdp, sc520_spunk. Among the modified and not tested targets there is a group of targets which were implementing their custom multi-partition scheme. This was mostly duplicating jffs2_part_info() routine code. Introducing the new common scheme required removing this duplicated code, so those targets should be especially carefully tested by the board main- tainers. Target list that require special attention: xsengine, voiceblue, mx1fs2, MPC8260ADS, innokom and VoVPN-GW (JFFS2 is by default not compiled in) and especially SXNI855T where the jffs2_part_info() routine was doing some custom NAND read caching. Thanks.

[U-Boot-Users] [PATCH] cleanup duplicated ARM interrupt code
by Andreas Engel 24 May '06

24 May '06

CHANGELOG: Cleaned up duplicated code: moved common ARM interrupt handling code from cpu specific interrupts.c files into lib_arm/interrupts.c. Patch by Andreas Engel, 21 Nov 2005 Signed-off-by: Andreas Engel Note: there were two cases (cpu/arm720t/ and cpu/sa1100/) where the disable_interrupts function only disabled IRQ, but not FIQ. I just ignored this in the generic function in lib_arm/, which disables both IRQ and FIQ. Perhaps someone with more knowledge of ARM cores can check whether or not this is ok. Regards, Andreas Engel

[U-Boot-Users] Kernel XIP
by shivappa.kushtagi＠wipro.com 19 May '06

19 May '06

Hello, I configured for kernel XIP and created xipImage. When I tried to load it through u-boot, it complained about invalid magic number. Later I added a 64 byte header required for u-boot with the following mkimage command: mkimage -A arm -O linux -T kernel -C none -a 0x00080000 -e 0x00080040 -d xipImage XIPImage. Actually some of the document found at CELF wiki specifies that we need to give "-x" option to mkimage. With -x option, mkimage fails with the following error message : mkimage: Bad file: "xipImage" has invalid buffer for XIP. After looking into the mkimage source code, found that it expects 0xFF for the first 64 bytes of xipImage. Which is missing in the xipImage I have built. There must be some in-consistency between the way xipImage is built or mkimage command. Also, I didn't find any significance of the code for "-x" if we specify the "entry point" correctly (load address + 0x40). After the mkimage, I flashed the XIPImage at address 0x00080000. After resetting the board, I got the following boot messages : ## Booting image at 00080000 ... Image Name: Image Type: ARM Linux Kernel Image (uncompressed) Data Size: 2009016 Bytes = 1.9 MB Load Address: 00080000 Entry Point: 00080040 Verifying Checksum ... OK XIP Kernel Image ... OK Starting kernel ... And it stops here.... Any idea what is going wrong here ? My configuration: Processor : ARM926EJ-Sid(wb) rev 3 (v5l) Kernel : 2.6.10 Regards Shivappa

The above, i couldn't acknowledge, but u-boot definitly hangs _after_ relocating to memory. it will dump 'Now running in RAM at .....'. But then it hangs. After relocating, it tries to manually relocate the command table. But that doesn't work. Don't know why, but with the patch it works. Obviously __u_boot_cmd_start = .; .u_boot_cmd : { *(.u_boot_cmd) } __u_boot_cmd_end = .; and __u_boot_cmd_start = ADDR(.u_boot_cmd); .u_boot_cmd : { *(.u_boot_cmd) } __u_boot_cmd_end = .; should be the same. However, this should be a binutils bug or the linker script voodoo that is done with the first script above isn't really valid. Maybe .u_boot_cmd gets misalligned. Maybe i should try to DEBUG(& __u_boot_cmd_start) in both (the patched and unpatched) versions to see, where it points, or maybe objdump show more. Btw. this happens on the tqm8xx board. Thanks to Vincent for recovering that, that saved me a lot of time... kind regards Anton Wöllert

[U-Boot-Users] Bug in DTT for temperatures below zero degress !!!
by Steven Scholz 14 Mar '06

14 Mar '06

Hi there, there's a terrible bug in the current U-Boot CVS concerning DDT: For temperature below zero the function dtt_get_temp() (at least for lm75) returns wrong values! ... DTT: 1 is 235 C LCD: Hitachi TX14D11 5,7" 320x240 TFT (235°C) WDT: disabled This is because of the use of an "int" although the lm75 only returns two byte ("signed short"). This trivial fix is needed: Index: u-boot/dtt/lm75.c =================================================================== RCS file: /cvsroot/u-boot/u-boot/dtt/lm75.c,v retrieving revision 1.2 diff -u -r1.2 lm75.c --- u-boot/dtt/lm75.c 27 Jun 2003 21:32:38 -0000 1.2 +++ u-boot/dtt/lm75.c 15 Jun 2005 08:44:21 -0000 @@ -174,7 +170,7 @@ int dtt_get_temp(int sensor) { - return (dtt_read(sensor, DTT_READ_TEMP) / 256); + return ( ((signed short) dtt_read(sensor, DTT_READ_TEMP)) / 256); } /* dtt_get_temp() */ #endif /* CONFIG_DTT_LM75 */ Then the output is correct: ... DTT: 1 is -28 C LCD: Hitachi TX14D11 5,7" 320x240 TFT (-28°C) CCFL: disabled (too cold!) WDT: disabled I am afraid this is an issues on all DTT in U-Boot. Some even only use "uchar". Comments? -- Steven
