Loading the application binary image to your board, and then running the application.My application task stopped working after waking up from stop2 mode. If I do not enter into stop2 mode its works fine.

But if its go to stop2 mode and wakeup it get stuck after a while. What I found is if I do not set the deepsleep bit in stop2 mode it works fine as soon as I set that bit, after a while couple of task stopped and those task have long delay as well about 10sec. If anyone have gone through this situation please help me or do you have any idea why deepsleep bit making problem. I run application for couple of days with high traffic but it never crash or stuck but as soon as seepsleep bit set it start getting stuck after a while.

Here is the clock setting before going to sleep or when it reset and first time clock configured. Those screen shots of the initialization structure are showing the wrong thing. Yes sure. If there is a context switch during your preparations for stop mode or during your recovery after stop mode, the other task allowed to run could be very confused — especially if it uses the HAL. One specific case worth extra consideration is the interrupt that wakes you from stop mode.

Be sure its ISR does not induce a context switch. That will protect you from context switches. This test code should use sleep mode instead of stop mode, so it should tell you whether stop mode is really at fault here. Yes, second solution solve the problem, but I have to use stop2 mode because for current consumption. Thanks for taking the time to report your solution.

It seems many people have struggled with the problems caused by letting the ST HAL use systick for its timebase. Freertos waking up from Deepsleep in stm32l4 Kernel. Are you using tickless idle?

Can you see in the debugger what the system is doing?

Can you post the task code that puts the system to sleep and wakes it up again? Hi Jeff, Here is the clock setting before going to sleep or when it reset and first time clock configured. This is After sleep. Then you might find an important clue.
