I received my STM32F446ret6-based PCB for my student project, PCB was already assembled from the JLCPCB factory and I can't program it through the SWD header with ST-link. I checked every trace on PCB with schematic and measured continuity with a multimeter, but no luck so far, still no connection. So I'm here to ask if you could spare some time and check my schematic or PCB, where that mistake is because I have lost any hope that I can find it myself.
