Case 1: without STOP2 mode UTIL_SEQ_SetTask or HW_TS_Start working fine.
Case 2: without UTIL_SEQ_SetTask or HW_TS_Start calling, the device can go to sleep and wake up without any problem.
case 3: when the device wakes up and after the device wakeup, if I use UTIL_SEQ_SetTask or HW_TS_Start device hangs up, and I am unable to debug also.
================Sleep code==========================

==============EXTI Wakeup code===============================
void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin)
{
SystemClock_Config();
HAL_ResumeTick();
UTIL_SEQ_SetTask(1 << CFG_TASK_ISR_CALLBACK, CFG_SCH_PRIO_0);
HAL_GPIO_WritePin(MY_LED_GPIO_Port, MY_LED_Pin,1);
Go_TO_SLEEP = true;
}
==========================================
Without sleep modes my implementation works fine, when i use sleep modes, once device wakeup's not able to use UTIL_SEQ_SetTask or HW_TS_Start.
Can someone please help me with my problem
Thank you,
