I am using the STM32L476 series controller in one of my projects. It is working as expected for all interfaces connected. But we are facing an issue of self-boot here.
We have observed following things during debugging:
- The controller starts booting after power ON/OFF sequence when it is connected with ST-Link debugger.
- As soon as I remove debugger and do ON/OFF sequence it fails to start booting process. Everytime we have to provide the manual reset to the controller to start booting.
- Out of 10 ON/OFF sequence, Controller hardly starts booting in 2 random times.
- Here I have also tried connecting BOOT0 pin with GND through 10K resistor.
For your reference, I have attached its schematic.
Let me know if any other details required.
