CC3230S: eMMC Support in CC32xx

Part Number: CC3230S

Could you confirm (nor not) that I can connect an external eMMC Flash Memory to CC32xx and get file-level (with FAT file system) API provided by the SDK?

    Hi Christopher,

    The CC3230 has a SD/MMC peripheral, but you should review the Technical Reference Manual to determine if it meets your needs.

    There is a third-party FatFS library included in the CC32xx SDK. You can find a fatsd example in the SDK.

    Note that in addition, you will still need a separate external serial flash dedicated to the network processor. See the datasheet for requirements.

    Best regards,

    Sarah

    Hi,

    Thanks for your fast reply.

    The Technical Reference Manual explain how the SD Host peripherals is working, but I can only see information related to SD Card stadard and not eMMC, which use a different low-level protocol.

    The Fatsd example has been made for an actual SD Card (on the BOOSTERPACK).

    I need a confirmation that the provied code is able to handle an eMMC chip instead of an SD Card. I knwo from other projects with other CPUs that the block-level procotol for accessing an eMMC in different than the one for SD Card and the coding effort could be very important if it is not provided by TI.

    Best Regards,

    Christophe

    Hi Christophe,

    If the SD Host driver does not provide what you need, then unfortunately we do not support eMMC drivers in the SDK.

    Best regards,
