K82: reset reason "Stop Mode Acknowledge Error Reset"

Hello !

 

I'm using LLS3 low power mode and sometimes I'm not able to go in it and sudden reset happens.

I have decode reset reason and it is always "Stop Mode Acknowledge Error Reset".

 

External LLWU pins are configured for wakeup and LPTIMER0 as well.

 

As usually  this type of reset is happens 2-3 times when I  flash K82 by JTAG.

 

It looks like some preconditions are not met and I need to clean someting after cold start/reboot.

 

Is any idea how-to  check all LLS3 preconditions and clean  pending events what might have effect to entering to LLS3 ?

 

MCUExpresso IDE and SDK is latest.

 

Regards,

Eugene
