I think that your writing of "schematic based on german nitrokey
version" may be not accurate expression, if it's for Gnuk, well, from
the author of FST-01* design. IIUC, at least some of Nitrokey board
designs are based on my FST-01 design, including the one which is almost
same circuit. Do you know the FST-01 design (no suffix version), or
the design of FST-01G?
It's good if you can show your schematics and how it's different to

Please elaborate your configuration of Gnuk.
For Gnuk with GD32F103 (examples are BLUE_PILL_G and FST_01SZ with
board-blue-pill-g.h and board-fst-01sz.h respectively), you can find
MHZ=96 in src/configure. This is important for GD32F103.
