Hello, I have a short circuit between the RESET and the VCC. I measure a impedance of 1ohm between these two signals and 80ohm with the GND. The RESET pin only goes on a 0.1UF capacitor and on the programming connector.

the ST-LINK can't detect the micro but the software who is already programmed in the micro work perfectly.Does anyone have an explanation why the reset breaks like this?
