    Hi,

    I've already tried these patches, but the issue persists.

    The main issue now is reading a 64-bit memory address. The mmc write command works with 32-bit addresses, but it does not function correctly with 64-bit addresses.

    Please review the MMC driver files related to handling 64-bit memory addressing. The issue is not related to configuring the memory node.

    Thanks,
