Question
STM32F07- act like a dead chip.
I have a board that used STM32F07. I connect BOOT0 pin to GND via RES 10kOhm and left NRST pin open. At first i able to connect to STM32 and upload code but problem is after first time upload code (I use debug mode). It show STM is disconnect and after that, I can't connect to STM32 and when i measure NRST pin is turn to 0.8V(At first is 3.3V) and even i try to pull up with resistor 10kOhm, it still the same voltage 0.8V. Does anyone meet the same problem? also can anyone explain to me why it like that?
