Hello Every1....

  I was looking for a schematic to interface an SD card with lpcxpresso lpc 1769 board. I dont have a baseboard. I found this schematic from one of the baseboard datasheet,

I use P0.7 for SCK, P0.6 for SSEL instead of PIO2_11 and PIO2_10. And rest as the same.

Above schematic shows a set of 10k and 270ohm resistor pullups. Do I need all of them to integrate with SD card socket ?

Thanx :)
