If there is a solder-bridge for NRST, consider removing that.

Hi Jan, hi Tesla,

thank you for ur answers.

The Problem is solved. Indeed there is a solid bridge between NRST and the on-board-developer (Pin T_NRST) at the buttom side.

I dont understand such a design because in such a case i await a jumper.

To close the SB again its fortunately possible to connect both pins on connectors at the top side.
