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?

    Custom board? Provide schematic 

    What's happening with VDDA?

    Can you pull BOOT0 HIGH so it doesn't run your code.
