I’m working on my own board which is based on STM32F103C8 which I designed and a very wired something happens with me.
I use st-link v2 to upload my code but after I uploaded my code, it won’t execute!
I tried a simple blink code example, but, without any luck. The voltage over the pin PA4 is always something between half and one volt.
I double checked the voltage over nrst pin (which is pulled down with 100n capacitor to GND) and it’s 3.3V. I checked even BOOT0 and BOOT1 pins (which both pulled down with 10K resistor to GND) and the voltage over them is 0V.
Did I miss something else? Or the IC is just fried and need to change it? Is it possible the IC is broken, but, I can upload any code to it?
