    Hello Manikandan,

    You can use the IAR debugger to determine the MCU status during hang-up: whether it is asserting (and the reason for it), attempting to access an invalid flash memory area, or otherwise.  From your description it is apparent that there is an issue with the hardware design, perhaps a faulty crystal or insufficient power supply.  You should closely follow the CC2538EM-RD and submit your design to SIMPLELINK-2-4GHZ-DESIGN-REVIEWS for further review.

    Regards,
