CC2642R: Sleep Wakeup Statergy

Dear Team,

Good evening!!

i am working with simple peripheral code; current SDK version is simplelink_cc13x2_26x2_sdk_5_10_00_48.

i am configuring the switch for wakeup from shutdown.

if i try to put the controller into the sleep mode; it went to the sleep mode.

but after pressing the switch its not wakeup.

above image refer to the GPIO pin configuration.

please find attached pin schematic snap for your reference.

attached code snippet is called into the main function.

PIN_Config ButtonTableWakeUp[] = {
    IGN_INPUT | PIN_INPUT_EN | PIN_PULLDOWN | PINCC26XX_WAKEUP_NEGEDGE,
    PIN_TERMINATE                                 /* Terminate list */
};

int main()
{

//       pthread_attr_t      attrs;
//       struct sched_param  priParam;
//       int                 retc;
