    Hello Jimmy,

    Probably a good way to handle this is to try first to flash NAND from already started u-boot (in example: from SD card). If that works, you will verify that everything else in your setup is OK and you have to seek the problem in your flashing procedure. How to flash from u-boot is explained here:
