    Hi Meng,

    Have you checked the sources in pdk_C66x_2_0_3/packages/ti/csl/example/mmcsd/ ?
    It provides example of raw access to mmc (no os required)

    Best Regards,

    Meng,

    Are you sure you have posted in the correct forum. C6655 doesn`t have a SD/MMC interface what interface are you using to access the SD card.

    Only AM57xx, DRA7xx and K2G devices from C66x family has the SD MMC interface so ensure that you provide the correct part number. Also, note we don`t support Linux on C66x core. Linux offering is only for the ARM devices.

    Regards,
