    Hi,

    On u-boot once you have a FAT partition on your card you can try the below:

    fatwrite mmc 0 addr filename size
    write file 'filename' from the address 'addr' in RAM of size bytes.
    Basically copying from RAM--->SD card.


    Then you can readback:

    fatload mmc 0 ${loadaddr} filename
    This will load from SD--->RAM.

    Then you can dump the contents of loadaddr using md command and can verify.
    Similar interfaced available for EXT4 partitions in u-boot to test:
    ext4write/ext4load.

    Hope this is what you are looking for.

    Best Regards,
    Keerthy
