Cannot mount sd card #17

In the former repo was an issue, mounting sdcard with the 6 pin module: https://github.com/carlk3/no-OS-FatFS-SD-SPI-RPi-Pico/issues/28

I had this problem too. Solution seems to be keep the connection cable as short as possible and use pullup resistors on MOSI and MISO. Before I wasnt able to mount the SD card. Afterwards I didnt run again into this problem

cheers
