    It would help if you could be more specific about what you mean regarding accessing the flash memory of the CC2430.

    What issues are you running into?

    I am trying to write any data into the non- volatile flash memory. That data will store permanently, if the device power off it will not effect into the data and whenever required I want to read that data. Please help me to solve this issue.

    Hi Sudip,

    Although written for the CC2510, the flash code found in the basic software examples here will work for the CC2430 as well after some modifications:
    http://focus.ti.com/docs/prod/folders/print/cc2510f32.html#toolssoftware

    The flash_asm.s51 needs to be modified to match figure 14 in the datasheet.
    The FWT register needs to be updated according to your clock.

    Regards,

    The answer to that question depends on *when* you want to write to flash:

    1) At program build time, you use the SmartRF board, or any of a number of 3rd party programmers to program your code into the devices' flash memory.

    2) During run-time, you can use osal_nv_item_init(), osal_nv_read() and osal_nv_write() to access flash memory.

    3) Selection of the NV_RESTORE compiler option allows routing, neighbor and address information to be stored into flash so that the devices' network state can be restored at start-up.
