Hi,

- show the circuit (your connections)

- show pic of your construction

to reduce the guessing about it.

Hello AScha,

Here I've added Screenshot of PCB schematic and Nucleo-Board schematic also and along with that I added physical connection snap .

Hi,

ok, so the target board is the big board in pic ?

But your circuit shows just F103 , even without crystal ?

Try connect with CubeProgrammer , set: software reset , normal; and show , what its "telling".
