I had the same problem with jumpers, for me worked this: in your library/utility in file Sd2PinMap.h the paragraph starting "// SPI port" the following paragraph rewrite to this: uint8_t const SS_PIN = 53; uint8_t const MOSI_PIN = 51; uint8_t const MISO_PIN = 50; uint8_t const SCK_PIN = 52;

this should help ;-)
