I am working with STM32 U575/U5A5 and L4 series of STM32 controllers in low power mode. I have programmed the controller to wake for every 10s and blink LED. This issue what we observed is once immediately flashing hex file to controller using STlink programmer, Controller is not entering in sleep mode LED will be keep on blinking. If I remove the power and connect it back, Controller is entering sleep mode and waking up for every 10s as expected.
we have reseted the controller using Reset button, but still controller is not entering to sleep mode.
The question here is why Controller requires power on reset to enter power saving mode after flashing hex file to controller using STlink programmer?
