Programming issues on Kinetis K20 with KDS 3.2.0

Hello everyone,


I'm trying to program a kinetis k20, more precisely a mk20dx256vlh7, using the SWD protocol and the U-Multilink- FX as a programmer.

I have connected to port B (20-pins) of the programmer which  datasheed says it's possible to program a kinetis MCU.

At the moment to program, an error comes up referring to whats it seems the comunication between the software and hardware, finally showing and error of the GDB server, I've tryed many configurations and always appears the same problem.


Has someone dealt with that problem or/and knows how to fix it?


Best regards,
