ECC error during mounting UBIFS volume

Artem Buslov
Prodigy 80 points
Other Parts Discussed in Thread: OMAP-L138, OMAPL138

Hello all!

I work with development board LCDK OMAP-L138. I have some problems with UBIFS on NAND device.

I use Linux kernel 3.3.0 from MCSDK OMAPL138 (processors.wiki.ti.com/.../MCSDK_OMAPL138_User_Guide_Chapter_Tools).

Kernel and rootfs image was built with Buildroot-2014.05 and GCC 4.4.7.

I change following parameters in Linux build configuration file (turn on NAND, MTD, UBIFS and turn off MMC):

MTD [=y];

MTD_NAND [=y];

MTD_NAND_DAVINCI [=y];

MTD_NAND_ECC_BCH [=y];

MTD_NAND_ECC_SMC [=y];

UBIFS_FS [=y];

MTD_UBI [=y];

Linux starts fine and founds MTD partitions.

I try to make UBIFS volume and mount it:

# mtdinfo /dev/mtd3

mtd3

Eraseblock size: 131072 bytes, 128.0 KiB

Does Linux NAND driver for DaVinci compatible device supports ECC properly?

Thanks in advance.

    Could you please attach the ECC error log.
    Try to boot the board with NFS then try to mount UBIFS partition in linux.

    Console output is under spoiler.

    ubiattach in first case and mount in second case failed with "UBI error: ubi_io_read: error -74 (ECC error)".

    Have I to send you an extended ECC error log? How can I get it?

    Why NFS? I boot the board via TFTP for debugging purpose.

    Hi Artem,

    Please refer to the following TI wiki page.

    processors.wiki.ti.com/.../UBIFS_Support

    I suspect that it could be problme on UBI file creating, you have to create with correct PEB calculation.

    free-electrons.com/.../creating-flashing-ubi-ubifs-images

    Regards,
    Shankari.

    Thanks for your answers. I have tried commands from TI wiki but the problem is not resolved.

    Commands from TI wiki page (or ):

    ubiformat /dev/mtd3 -s 512 -O 2048

    ubiattach /dev/ubi_ctrl -m 3 -O 2048

    fails with UBI error -74 (ECC error). Error log in first post.

    An another method from e2e forum:

    flash_erase /dev/mtd3 0 0

    ubiattach /dev/ubi_ctrl -m 3 -O 2048

    ubimkvol /dev/ubi0 -N rootfs -s 20MiB

    mkdir /mnt/nand

    mount -t ubifs ubi0:rootfs /mnt/nand

    These commands raise similar ECC error. Error log in first post.

    Thanks in advance.

    I made experiment. I wrote one page in the size of 2048 byte two times by u-boot and by linux. I checked what was written and that ECC.

    U-boot sent this commands:

    nand erase 0x540000 0x800
nand dump.obb 0x540000
tftp 0xc0700000 192.168.0.115:nand_page
nand write 0xc0700000 0x540000 0x800
nand dump.obb 0x540000

Page 00540000 dump:

    Conclusion

    Data is the same but ECC is different. This can be the cause of error mounting NAND to Linux. That should we do to make ECC the same?

    I found out that U-boot and Linux NAND drivers use different Error Correction Code algorithms. U-boot uses 4-bit hardware ECC algorithm and Linux uses 1-bit hardware ECC algorithm. One of the comments to Linux NAND driver source file mentions that this driver doesn’t support 4-bit ECC for 16-bit flash.

    In spite of that, I made an attempt to adapt the driver’s NAND algorithm to 4-bit mode (in the file board-omapl138-lcdk.c)

    I wrote a sample NAND data page by Linux and then tried to read it with Linux and then with U-boot. The data I read with Linux was incorrect, and the data I read with U-boot was just the same as the initial data page. The issue is that Linux driver with 4-bit ECC on writes Data and OOB correctly, but reads Data incorrectly and OOB - correctly.

    So wouldn’t you please tell me if you got any Linux patch or driver for 4-bit hardware ECC to be used with DaVinchi? I’d be happy to have it in my disposal.

    Thanks in advance.

    The NAND EMIFA latencies in Linux driver were configured for clock frequency 300 MHz but actually run on 456 MHz. I resolved the issue by switching Fclk to 300 MHz.
