Hi All,
I'm new to using the STM32 and honestly had great grief trying to connect to the chip.
I'm using STlink V3 and designed my own PCB.
Trying to flash a F/W to the PCB.
I ordered the PCB from JLCPCB.
I keep getting unable to get core ID as a message and I can't figure out why?
I seem to be able to connect for a few seconds but than i get a message, unable to get core ID and it disconnects.
When I compile a code and try to flash it, it also tells me flash successful but I don't think the code got flashed successfully as the chip doesn't work as expected and also I am still unable to connect to it and i get messages unable to get Core ID.
Any help or suggestions? I have the RST connected to GND with a resistor, schematics attached.
