8 years agoWe have found a workaround. It was hardware issue. One of these pins was connected to the external button with hold up. I don't remember which pin it was, i can check in the next week. When We tested our hardware without external button everything was working. The default state on this pin was High. When we added external button it was working randomly because when the button was upholded it forced Low state on the pin and caused power up problem. In the next our hardware revision we try no to use config pins as IO.
