I made a board for a project with an stm32 (first time with stm32) chip (stm32f407vgt6) but the reset button doesn't seem to work. It only works when connected to STlink
Let's see well I'm looking cant see nothing.
You have to give more then this to help you.
Post your circuit you used some pictures of what you did that would be great start.
Oh sorry, i had posted pictures but i somehow removed them.
I attached the schematic from the development board(diymore) i used and my schematic (1).
thanks
Check your NRST pin. There should be a 100n cap hanging off this and an internal pullup turned on. Stlink will handle the reset itself, but when it is disconnected your circuit needs to handle it and unless the internal pullup is on it will not work.
