    Hi Dwight

    No plans to upgrade the OMAPL138 RBL to support eMMC v4.41.
    The RBL support for MMC/SD including eMMC is as stated in the boot loader application note

    The MMC/SD boot mode is compliant with version 2.0 of the SD specification and version 4.2 of the
    eMMC specification. The boot loader and MMC/SD peripheral does not support features of the eMMC 4.3
    or 4.4 specifications related to boot (no boot operation mode and no support for boot partitions). The AIS
    boot image is expected to be in the user data area of the memory device, written to address 0 of that
    region. The bootloader detects the AIS image by checking for the magic word (0x41504954). If the magic
    word is not found, the bootloader increments the starting address by 0x200 and tries again. The
    bootloader fails if the magic word is not found within the first 2 MB of the memory card.

    Regards
