[U-Boot-Users] write u-boot.bin on mpc8349e-mITX-gp with bdi2000

Hello. Now I'm trying to write u-boot.bin on mpc8349e-mITX-gp with bdi2000. But I don't have correct bdi2000 configuration file for mpc8349e-mITX-gp. How can I write u-boot.bin on that board? Unfortunately I erased u-boot area on that board so there no u-boot anymore on that board. Is there anyone can show bdi2000 configuration file for mpc8349e-mITX-gp? Or please let me know how to write u-boot on that board with bdi2000. I'll appreciate any comments. -- View this message in context: http://www.nabble.com/write-u-boot.bin-on-mpc8349e-mITX-gp-with-bdi2000-tf3… Sent from the Uboot - Users mailing list archive at Nabble.com.

[U-Boot-Users] is it possible to program a DIGI connectme arm7 device with Macraigor JTAG raven or Altera Byteblaster II cable with u-boot software ?
by Guglielmo Fanini 07 Jun '07

07 Jun '07

I would like to read the 2mb flash of a DIGI connectme -S ARM7 TDMI (I think it is at least) based embedded board and program it back, is it possible to use Macraigor parallel-JTAG raven cable or Altera Byteblaster II parallel download cable and u-boot software. Which cpu should I specify of ARM7 : LIST_ARM7="B2 ep7312 evb4510 impa7 modnet50" Are there any links to DIGI ARM7 and u-boot information anywhere ? thank you.

Re: [U-Boot-Users] u-boot on nadflash for at91sam9260ek

Hi Victor We have the same problem. The u-boot 1.1.5 code from Atmel does not correctly support the ECC correction coding in the OOB (out of bounds) area of the nandflash when writing. I have tried playing around with the available settings to no avail. When you do saveenv the data is correctly written to nand flash but the oob area is filled with a 12 byte ECC code which makes the 5th byte in the OOB something other than FF and thus marks the sector as bad. The hw ECC controller of the AT91SAM9260 is hard coded to generate a 4 byte ECC in the first 4 bytes of the OOB. This is the ECC used by SAMBA (external pc programming tool) and the linux at91-nand driver. I have not found any support for this in the Atmel u-boot code (yet). If anyone has fixed AT91SAM9260 hw ECC support in u-boot please send us a copy of your changes. Even a sw ECC that generates a correct 4 byte code would be useful. U-boot on at91sam9260 can however read from nand (i think it ignores ECC by default) so its possible to boot an image that you have written to nand, its just not possible to write to nand from within u-boot. I use either samba or linux (flash_eraseall and nandwrite) to write data to the nandflash and fw_setenv and fw_printenv (compiled from u-boot tools dir) to modify u-boot environment variables during development Atmel has a port of u-boot 1.2 available on www.at91.com. I have not been successful it getting that version to run yet. Does anyone know if it includes support for nandflash writes from u-boot?

[U-Boot-Users] u-boot on nadflash for at91sam9260ek
by Victor Librado 07 Jun '07

Hello all, I'm working with u-boot for booting in nandflash with the evaluation board atmel at91sam9260ek. Nandflash reads ok, but performing and erase doesn`t work. I get these messages trying to erase a block of the nand and writing the environment variables to nandflash. Any help? I'm missing a configuration parameter in config or what may happens?

[U-Boot-Users] [PATCH] bug in README and soft_i2c.c
by Andrew Dyer 07 Jun '07

07 Jun '07

Hi, I noticed a bug in soft_i2c.c (or in the README depending on how you think about it). If CONFIG_SOFT_I2C is defined and using open-collector I/O, then the README says that I2C_TRISTATE can be defined as null. If this is the case, then doing: imd 29 0.0 2 will cause the following chain of calls in soft_i2c.c: send_start() write_byte() read_byte() read_byte() send_stop() The first read_byte() calls send_ack(0). send_ack(0) drives the data line low without releasing it. The following call to read_byte() calls I2C_TRISTATE, but in this case it is defined as NULL per the README. This leaves the data line driven low during the read of the 2nd byte causing data^h^h^h^hhair loss that I can ill afford :-) I propose the following fix - modify the README to make say that I2C_TRISTATE should be defined even for open-collector setups, and add code to soft_i2c.c to explictly tristate the data at the end of send_ack(0) Signed-off-by: Andrew Dyer <amdyer(a)gmail.com> -- Hardware, n.: The parts of a computer system that can be kicked.

[U-Boot-Users] IXP4xx Silicon version
by Jonathan Pratt 07 Jun '07

07 Jun '07

Hi all I'm not sure if anyone else has found it to be a problem but some boards we recently had built have an IXP425 on them which reports a Product Revision value 0x2 (lowest four bits of CP15, reg 0). This is only a problem because the file cpu/ixp/npe/npe.c uses this field in the npe_initialize function to decide how to determine how many ethernet ports there are. Unfortunately the case statement only accounts for revision values 0x0 (IX_FEATURE_CTRL_SILICON_TYPE_A0) and 0x01 (IX_FEATURE_CTRL_SILICON_TYPE_B0) so that the existing code doesn't think that these processors have any ethernet ports available. I found that by adding a 'default:' statement before line #639 remedied the problem. This file is part of u-boot, not the Intel npe library. Since it seems that someone is immanently about to release a patch on the npe stuff anyway, would it be too much trouble to add the 'default:' statement or otherwise handle this product revision?

I am using the same value for the SMC registers as stated in my linux kernel board-at91sam9260ek.c. In linux I can perform nandflash read/erase/write ok. (flash_eraseall / nandwrite commands). May I have to define the JFFS2 partitions in u-boot configuration my_board.h as I have in Linux? Commands: *CONFIG_JFFS2_NAND_OFF*, CONFIG_JFFS2_NAND_SIZE ...? Regards, Víctor Victor, you should check registers settings and timing into yourboard.h configuration file Ciao Victor Librado ha scritto: > > > > Hello all, > > I'm working with u-boot for booting in nandflash with the evaluation > > board atmel at91sam9260ek.
