STM32F072 PowerOn Not in Run Mode

Question asked by mattoo.anuj on May 21, 2017

I have STM32F072 Discovery board, I am running some demo program, now the issue is, when I power on the discovery with USB or external supply, it doesn't boot into run mode/Program Mode, I have to reset the MCU, in order to run it. 


Where is the issue? I am unable to understand.
