    Hi All,

    I am also facing very similar issue which Chakravarti has mentioned. I have a board which is customized version of DM355 EVM board having MT29F16G08CBACA NAND flash. When I try to flash UBL and u-Boot using "sfh_DM35x.exe" utility, it gives me an error indicating that "Write verify failed. Skipping block!!"

    I have looked in to the reference manual of DM355 EVM and it is mentioned that its RBL (Rom boot-loader) does not support NAND having page size more than 2K (But the flash I am using -MT29F16G08CBACA is of 4K page size). So my queries are:

    1. Have RBL been upgraded to support NAND flash with 4K page size? If Yes then from where can I download this upgraded RBL and how to flash it on board?
    2. What are the other alternatives to support the flash with 4K page size ? Do I need to make any changes in UBL/u-Boot code? If Yes, can you please address me a proper reference document for such changes?
    Thanks,
    Rajesh
