DM816X is not booting ...when I try to writing NAND  ..it fails as below 

 

 

Choose the ECC scheme from given options :

Enter 1 ---> BCH 8 bit 

Enter 2 ---> HAM  

Enter 3 ---> T0 EXIT

Please enter ECC scheme type :

    Hi,

    Another option to the flash writer is to use uboot itself.

    You could also try flashing the uboot to NAND from uboot itself. Create an Bootable SD Card. Boot from it to uboot prompt. Uboot can then be flashed to NAND.

    The following instructions can be used with the latest EZSDK (5.03.01.15)

    From the EZSDK use the mksdboot script to create a bootable SD card. Then use the setup-nand-images.sh to flash the uboot to your NAND. Both these scripts are available in your EZSDK installation bin/ directory.
