Hi TI, 

Is external memory required for the CC3235MODASF/CC3235MODAS to receive OTA?

Is 32Mb sFlash internal to CC3235MODASF/CC3235MODAS enough to do OTA?

Thank you very much.

Best Regards.

    Hi,

    32Mb internal flash is perfectly fine for OTA updates. OTA examples in CC32xx SDK are build around this flash size.

    And yes, the external flash is mandatory (the file system is implemented on the external flash).

    The internal flash (in SF device/module) is used for the MCU image code (eXecute In Place). The MCU image provided in an OTA image, will be stored on the file system and then copied to the internal XiP flash by the bootloader.
