Fitting R42 resistor on Evb1000


I am still struggling to set Spi communication between F407 and Evb1000 board. I have read the datasheet again and again to not miss any detail. When I looked at schematics, I realized the second pin of Spi header fits R42 resistor. What does this mean? What am I supposed to connect to that pin?

Dear Halil,

This is just to ensure compatibility with the Total Phase Cheetah SPI adapter which has GND connected to Pin 2 of its standard connector. If you are not using this SPI adapter then this pin does not need to be connected. You only need to connect the SPI signals, IRQn and the ground on pin 10.

Kind Regards
