I use u-boot version is u-boot-2010.06-psp04.04.00.01.

But, when I use the version u-boot-2010.06-psp04.00.00.01, the ECC error can not happen. what may the problem for u-boot-2010.06-psp04.04.00.01 version? and how to solve the problem?

 

Thanks,

Chen

 

 

  • Chen,

    This could be because the previous version of the u-boot or the NAND memory area is written using a different ECC scheme.

    Please erase the complete NAND area using the following command and try flashing the u-boot image
