nand boot using am335x platform

anil kumar23
Expert 1190 points

Hi,

I am using 1GB nand (1024MiB, page size: 4096, OOB size: 224) in my am335x platform and trying to boot from NAND, it is running and my applications also running.

But problem is while booting at the beginning the continuously the below error messages are coming which is taking more booting delay.

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

nand: error: uncorrectable ECC errors

nand: error: uncorrectable ECC errors

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

How to avoid these errors and to improve my booting speed as well. I am refereeing SDK7 with Linux 3.12 version .

I have modified in U-boot & Kernel for changing ECC of the NAND settings.

Find attached boot log which you will understand the problem what i am facing.

Please suggest me how to improve and remove the errors.

Regards,

Anil

    Hello,

    You need to flash the uboot/ kernel in bch16 mode, for 4K page size.
    how are you flashing the images from linux/ uboot ? does it support bch16 ?

    Cheers,

    Hi,
    Yes i am using BCH16 mode, I am have modified in the u-boot configuration file (inlcude/configs/am335x_evm.h) the below changes are done under only u-boot. In dts file i have chnaged the NAND partitions only. Not modified any drivers.

    Hi,

    I have only enabled and changed the configuration in U-boot only. Where should i change the BCH16 changes in Linux.

    Could you please suggest me the settings and configuration under Linux.

    Regards,
    Anil

    Hello,

    When you do a menuconfig, go into drivers-->> mtd-->>> NAND--> when you select omap2 nand there it has option to choose BCH8/BCH16
