Hi Friends, I am having problem with 16MB M29W128GL Flash. I am getting Flash Not Erased when i try to use saveenv command at u-boot command prompt. I have tried manually Byte by Byte wise writing to NOR Flash location so for that i have use following command and getting 2 same byte write on consecutive location. And when i have try to write word using mw.w then it writes correct. Before use command: -> md 0x50000 00050000: ffffffff ffffffff ffffffff ffffffff ................ 00050010: ffffffff ffffffff ffffffff ffffffff ................ 00050020: ffffffff ffffffff ffffffff ffffffff ................ 00050030: ffffffff ffffffff ffffffff ffffffff ................ 00050040: ffffffff ffffffff ffffffff ffffffff ................ 00050050: ffffffff ffffffff ffffffff ffffffff ................ 00050060: ffffffff ffffffff ffffffff ffffffff ................ 00050070: ffffffff ffffffff ffffffff ffffffff ................ 00050080: ffffffff ffffffff ffffffff ffffffff ................ 00050090: ffffffff ffffffff ffffffff ffffffff ................ 000500a0: ffffffff ffffffff ffffffff ffffffff ................ 000500b0: ffffffff ffffffff ffffffff ffffffff ................ 000500c0: ffffffff ffffffff ffffffff ffffffff ................ 000500d0: ffffffff ffffffff ffffffff ffffffff ................ 000500e0: ffffffff ffffffff ffffffff ffffffff ................ 000500f0: ffffffff ffffffff ffffffff ffffffff ................ After use command: (Here i have try to write 0x12 on 0x50000 location but it writes two same bytes on 0x50000 & 0x50001) -> mw.b 0x?50?aaa 0xaa -> mw.b 0x50554 0x55 -> mw.b 0x50aaa 0xa0 -> mw.b 0x50000 0x12 -> md 0x50000 00050000: 1212ffff ffffffff ffffffff ffffffff ................ 00050010: ffffffff ffffffff ffffffff ffffffff ................ 00050020: ffffffff ffffffff ffffffff ffffffff ................ 00050030: ffffffff ffffffff ffffffff ffffffff ................ 00050040: ffffffff ffffffff ffffffff ffffffff ................ 00050050: ffffffff ffffffff ffffffff ffffffff ................ 00050060: ffffffff ffffffff ffffffff ffffffff ................ 00050070: ffffffff ffffffff ffffffff ffffffff ................ 00050080: ffffffff ffffffff ffffffff ffffffff ................ 00050090: ffffffff ffffffff ffffffff ffffffff ................ 000500a0: ffffffff ffffffff ffffffff ffffffff ................ 000500b0: ffffffff ffffffff ffffffff ffffffff ................ 000500c0: ffffffff ffffffff ffffffff ffffffff ................ 000500d0: ffffffff ffffffff ffffffff ffffffff ................ 000500e0: ffffffff ffffffff ffffffff ffffffff ................ 000500f0: ffffffff ffffffff ffffffff ffffffff ................ When try to write word using mw.w then it writes correct: -> md? ?w.w 0x50?aaa 0xaa -> mw.w 0x50554 0x55 -> mw.w 0x50aaa ??xa0? ? -> mw.w 0x500?10 0x1234 -> md 50000 00050000: 1212ffff ffffffff ffffffff ffffffff ................ 00050010: 1234ffff ffffffff ffffffff ffffffff .4.............. 00050020: ffffffff ffffffff ffffffff ffffffff ................ 00050030: ffffffff ffffffff ffffffff ffffffff ................ 00050040: ffffffff ffffffff ffffffff ffffffff ................ 00050050: ffffffff ffffffff ffffffff ffffffff ................ 00050060: ffffffff ffffffff ffffffff ffffffff ................ 00050070: ffffffff ffffffff ffffffff ffffffff ................ 00050080: ffffffff ffffffff ffffffff ffffffff ................ 00050090: ffffffff ffffffff ffffffff ffffffff ................ 000500a0: ffffffff ffffffff ffffffff ffffffff ................ 000500b0: ffffffff ffffffff ffffffff ffffffff ................ 000500c0: ffffffff ffffffff ffffffff ffffffff ................ 000500d0: ffffffff ffffffff ffffffff ffffffff ................ 000500e0: ffffffff ffffffff ffffffff ffffffff ................ 000500f0: ffffffff ffffffff ffffffff ffffffff ................ So what may be problem? Internally it uses following command (8bit x b bit). Is it problem? it should be 16bit x 8 bit? fwc addr 00040aaa cmd aa aa 8bit x 8 bit fwc addr 00040554 cmd 55 55 8bit x 8 bit fwc addr 00040aaa cmd a0 a0 8bit x 8 bit Thanks & Warm Regards, Ramesh Khokhani Senior Software Engineer [X] ................................................................................................................................................... ramesh.khokhani(a)igatepatni.com ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Disclaimer~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Information contained and transmitted by this e-mail is confidential and proprietary to iGATE and its affiliates and is intended for use only by the recipient.

[U-Boot] [PATCH] Remove unused CONFIG_SYS_I2C_BUS[_SELECT]
by Michael Jones 16 Jan '13

16 Jan '13

"CONFIG_SYS_I2C_BUS" and "CONFIG_SYS_I2C_BUS_SELECT" don't appear anywhere outside of config files. Signed-off-by: Michael Jones <michael.jones(a)matrix-vision.de> --- As far as I can tell, these CONFIG options never have existed outside of these config files - looking at omap3_beagle.h as an example, these lines were inserted with the creation of that file, and at that point in time there was also no occurence of them elsewhere.

[U-Boot] [PATH v3 1/2] sf: Add status register reading support
by Jagannadha Sutradharudu Teki 16 Jan '13

16 Jan '13

This patch provides support to read a flash status register. Status register contains a control bits used to verify the progress of flash program and erase operations. User need to get the data through spi_flash_cmd_read_status() based on their usage.

[U-Boot] [U-Boot-Users] standalone code
by Diego Preciado Barón 15 Jan '13

15 Jan '13

Hello, I want to use the u-boot drivers such as gpio and spi on a standalone application. What do I need to modify in the Makefile to build and link my code with the rest of the U-boot code in order to include those drivers in my application? because when I try to compile my code, it shows some errors of undefined references. Is it possible to run that application automatically when the u-boot starts? maybe from the SD card? Thanks.Diego Preciado

[U-Boot] Googlers please reply: commiters in U-Boot
by Simon Glass 15 Jan '13

15 Jan '13

Hi, You are being copied because you have written U-Boot code which is now in mainline. The chromium.org domain does not automatically attribute U-Boot commits by company. Each author needs to be manually added to the list and this can only be done if you confirm your employer. So, if you are on the CC list and work at Google, please reply-all with a quick email stating this (without top posting). Regards, Simon

[U-Boot] NAND flash - bad blocks
by Dimitar Penev 15 Jan '13

15 Jan '13

Hello, First of all sorry if this question was already answered here. We are sourcing some K9F8G08U0M-PIB0 NAND flash devices. On the first erase in uboot 2011.09 I got bunch of mostly consecutive bad blocks. According to the datasheet we should get not more then 80 bad blocks for our chip but I get something like 240 bad blocks for most of the NAND chips. I seems to be able to fix this using the following procedure: In uboot uboot>nand scrub.chip In uboot uboot>nand erase.chip clean at this point I get usually 1,2 bad blocks which looks normal to me. In Linux we have few mtd partitions on this NAND chip. Unmount all of them and for all of them : linux>nandtest -m /dev/mtdx Usually this doesn't add any new badblocks on top of what I get on nand erase in uboot, but I really haven't tested that much device to say. After this procedure the NAND flash seems to work fine. Do you think this is reliable way? Is there something better I can do? Has anyone got NAND component batch having more bad blocks then datasheet allows. Should we consider the provider unreliable? Thank you Dimitar

Currently booting from internal mode is not supported in U-boot for mx35, so remove it from the list of supported SoCs.

[U-Boot] Read-only env variables
by Joe Hershberger 15 Jan '13

15 Jan '13

Hi u-boot, I see u-boot supports readonly serial# and ethaddr, but I have a few other variables that I need to be read-only. I'm planning to implement a generic list of variables that cannot be changed or deleted. I'm interested to know what sort of specification people would find most appropriate. My current thought is to follow the same delimiter as the env itself, i.e. null separated list with double null terminator. This list would then be defined in the board config header. It also seems that you should be able to specify simple access rules for each variable name perhaps using "=<val>" after each var name where <val> could have constants (probably numbers for performance, but could be string literals) to define modes. Right now I'm thinking read-only, create-only, change-default, and change-only (i.e no delete) are the modes that make sense. I'm also interested if anyone would be opposed to simply using this new specification of readonly vars to implement the serial# and ethaddr protection. The CONFIG_HAS_UID is a bit odd... should that be available in general for read-only vars? Comments? Thanks, -Joe
