OMAP-L137 Bad Data CRC during kernel boot

Other Parts Discussed in Thread: OMAP-L137, BIOSLINUXMCSDK, OMAPL138

The products being developed using the OMAP-L137 to the following error:

Loading from NAND 512MiB 3,3V 8-bit, offset 0xc0000

This problem does not happen often, it appears once every few months.

While searching a solution, I found a post with a similar issue in TI forum.

http://e2e.ti.com/support/embedded/linux/f/354/t/73788

The content of the post,Richard Counts wrote that there is a problem with the U-BOOT.

Processor and U-Boot is different. But the problem is similar.

I would like to know that there arn no problem in the U-BOOT code of OMAPL137.

I am using the code and hardware information is as follows.


OMAPL-137 custom board with a NAND FLASH(MT29F4G08ABADAWP).

The codes used were downloaded from the site below.

    Yes, the problem seems to be the ECC misbehavior in u-boot.
    You will not face this error if you use updated u-boot from latest MCSDK release.

    Thank you for reply.

    I was searching for MCSDK.

    http://www.ti.com/tool/BIOSLINUXMCSDK?keyMatch=mcsdk&tisearch=Search-EN

    But I did not find a MCSDK for OMAP-L137.

    Where can I get a MCSDK for OMAP-L137 or latest U-BOOT for  OMAP-L137 ?

    Hi Myeongsu Han,

    MCSDK is not available for OMAPL137. It is for OMAPL138.

    For OMAPL137, only BSP , CSL and Davinci PSP packages are available.

    You can find the latest U-Boot of OMAPL137 in Davinci PSP package.

    However, you can use the Davinci PSP package enclosed in the MCSDK of OMAPL138 which will have the latest U-Boot as Titus mentioned.

    Shankari
