Read Page Issue on 16 Bit NAND flash

Hello,

We're trying to access a 16 bit nand flash (MT29F2G16)  via the tool --> \nand-flash-writer_AM335x. 

The details (Device ID & Manufacture ID, ...etc) of the NAND flash can be get  with no error, but the program always stop in this line: 

  // Clear the ECC hardware before starting
  (*hNandInfo->hEccInfo->fxnDisable)(hNandInfo);

Please anyone help how to address the issue.

Thanks,

Elvis

    Hi,

    Could someone help to give advice how to solve the issue on the nand-flash-writer_AM335x tool.

    The NAND_readPage function in nand.c will always return "E_FAIL" when execution the line below:

    if ((*hNandInfo->hEccInfo->fxnCorrect)(hNandInfo, (block * hNandInfo->pagesPerBlock) + page,
    spareBytes, &dest[hNandInfo->dataBytesPerOp * i], i) != E_PASS) 
                return E_FAIL;

    Is it any part wrong?

    Thanks,

    Elvis

    Hi Elvis,

    The nand-flash-writer utility in the starterware package works for 8bit Nand device by default. You need to change it for your Nand part which is 16bit.
