With the aid of a logic analyzer I Have found that the chip select signal was coming from another pin than the expected.

It took me a long run to adapt the code, but I could finally boot in on the Blue Pill.
- Download and install STM32 duino
- Include directives for every hardware dependent instruction (same code can still be compiled to Mega328 based Arduino)
- Fiddle with one configuration defitinion for SDFat library
- Adapt the code to compile for newer PCD8455 display library
