    Hi,

    Sorry for the late response.

    The CC2538 debug interface (cJTAG/JTAG) is described in chapter 6 of the CC2538 User's Guide (SWRU319). The device memory map is described in chapter 4.

    The CC2538 has a ROM API available with functions for erasing and writing the CC2538 flash, see chapter 3 of SWRU333. This document also describes the CC2538 serial bootloader which can be used to program the device.

    Using the debug interface, flash programming can be done as listed here:

    1. Connect to device
    2. Copy data to program into device RAM
    3. Call ROM API function for erasing/writing flash pages (sector erase size is 2048 bytes)

    Useful info:

    • CC2538 sector erase size is 2048 bytes
    • Flash starts at address 0x0020.0000
    • SRAM starts at address 0x2000.0000

    Hope this helps!
