    Hi Yue,

    There is some information on the CC3200 boot sequence in the datasheet section 5.9 (pg 55). 

    The bootloader does not write to the external flash. However, the sl_Start() API to initialize and run the network processor does write to flash to store data such as antenna calibration results. Furthermore, simplelink APIs that configure the persistent settings of the NWP such as sl_WlanPolicySet() also write to flash. Thus, customers should be more concerned about the various sl_*() APIs that write to external flash when evaluating flash wear lifetimes.

    Regards,
    Michael
