ecc error in nand

daniel formolo
Intellectual 805 points

Hi,

it is usually write flash with the commands bellow. But when I write just a part of whole system, for example: 

fatload mmc 0   0x81280000 uImage.bin
nand write 0x81280000 0x280000 0x500000
in general ECC errors appear or the system initialization stops in uboot. The same happen when use nandwrite command in linux. Someone has any idea about it? how to resolve it?
 

whole system writing:

------------------------------------------

mmc rescan
nand erase.chip
fatload mmc 0 0x81000000 MLO
cp.b 0x81000000 0x81020000 20000
cp.b 0x81000000 0x81040000 20000
cp.b 0x81000000 0x81060000 20000
fatload mmc 0   0x81080000 u-boot.img
fatload mmc 0   0x81260000 uEnv.txt
fatload mmc 0   0x81280000 uImage.bin
fatload mmc 0   0x81780000 ubi.img
nand write 0x81000000 0x0 0x2000000
saveenv

    solved the problem with a basic procedure. Always need erase the block before write in it: nand erase command.

    Hi,

    I am also following the same above steps for flashing the images to my NAND.  when i booted the systems from NAND is booting, but it is not mounting to rootfs (ubi). 

    Please find the log issue and resolve my issue.

    could you provide me your uEnv.txt arguments.. Please do the needful.

    Thanks

    Hello Lofna,

    It seems that your NAND is not detected by the kernel or you have passed wrong boot arguments. Could you attach all the logs from the beginning and provide more information about your board and SDK?

    Best regards,
    Kemal

    HI Kemal,

    I am using AM335x Linux 3.2 Version & u-boot from SDK6 version.

    Please find the booting log which says NAND detection

    Hello Lofna,

    If you use the UBI image provided by SDK6 you should change the value of the U-Boot argument  "nandroot"  from  "ubi0:rootfs" to "ubi0:am335x-evm-rootfs".

    In order to boot from NAND the following changes should be enough.

    U-Boot# setenv nandroot ubi0:am335x-evm-rootfs rw ubi.mtd=7,2048
U-Boot# setenv bootcmd run nandboot
U-Boot# saveenv

    Best regards,

    Kemal

    Hi Kemel,

    I have given the above NAND boot arguments in my u-boot. But still the errors are occurred.

     Find attached log for your reference.

    Hello Lofna,

    You are not writing the whole UBI image to the NAND. Try this command.

    fatload mmc 0 0x82000000 MLO;nand write 0x82000000 0x00000 0x20000;nand write 0x82000000 0x20000 0x20000;nand write 0x82000000 0x40000 0x20000;nand write 0x82000000 0x60000 0x20000;fatload mmc 0 0x82000000 u-boot.img;nand write 0x82000000 0x80000 0x60000;fatload mmc 0 0x82000000 uImage;nand write 0x82000000 0x280000 0x500000;fatload mmc 0 0x82000000 ubi.img;nand write 0x82000000 0x780000 0x1200000;

    Hi Kemel,

    Still i am getting the same error.

    Could you send the required source files in U-boot & kernel for my understanding.

    THanks

    Hello Lofna,

    I haven't changed anything on my Kernel and U-boot source. I use the prebuilt images from SDK6:

    filename: bytes: md5sum:

    MLO-am335x-evm 100549 70b894689451f22fe10e254cc4ad273f

    arago-base-tisdk-image-am335x-evm.ubi 26607616 b251aae1e4124566684cfa14155619ba

    Flashed them by the following commands:

    nand erase.chip

fatload mmc 0 0x82000000 MLO

nand erase 0x0 0x20000

nand write 0x82000000 0x0 0x20000

fatload mmc 0 0x82000000 MLO

nand erase 0x40000 0x20000

nand write 0x82000000 0x40000 0x20000

fatload mmc 0 0x82000000 MLO

nand erase 0x60000 0x20000

nand write 0x82000000 0x60000 0x20000

fatload mmc 0 0x82000000 u-boot.img

nand erase 0x80000 0x40000

nand write 0x82000000 0x80000 0x40000

fatload mmc 0 0x82000000 uImage

nand erase 0x00280000 0x00500000

nand write 0x82000000 0x00280000 0x500000

mw.b 0x82000000 0xFF 0x1960000

fatload mmc 0 0x82000000 arago-base-tisdk-image-am335x-evm.ubi

nand erase 0x780000 0x0f880000

nand write 0x82000000 0x780000 0x1960000

    U-boot env:

    setenv nandroot ubi0:am335x-evm-rootfs rw ubi.mtd=7,2048

setenv bootcmd run nandboot

saveenv

    It boots and works like a charm.

    Have you ever tryed to flash the ubi image from user space.

    flash_erase /dev/mtd7 0 0

ubiformat /dev/mtd7 -f ubi.img -s <subpagesize> -O 2048

    Could you also post the feedback from these commands?

    #U-Boot:

    mtdparts

    Boot from SD card

    #Linux:

    mtdinfo -a

mtdinfo -u /dev/mtd7

    Kemal

    Hi Kemal,

    I am using Spansion S34ML08G2 (8 Gb, 4-bit ECC) Still i am unable to boot from NAND with my ubi file system. Kernel is booted but my file system is not booting. I am using SDK7 u-boot and changed some parameters in my config files. as per your steps followed below:

    Hi Kemal,

     After changed the offset in u-boot, now i am able to boot uImage from NAND, but still i am facing UBI ecc error. My file system is not linking.

    getting the error:

    UBI error: ubi_io_read: error -74 (ECC error) while reading 64 bytes from PEB 0:0, read 64 bytes
    UBI error: ubi_io_read: error -74 (ECC error) while reading 512 bytes from PEB 0:2048, read 512 bytes

    Please find attached log.

    Thanks
