Hi all

I found my problem. Remember to initialize this pin to '1' in the FPGA, if using Motorola SPI frame format ('0' for TI SSP): 

hps_0_spim0_ss_in_n                                 => '1'

Now it works!

Best regards

Brian

    Thank you so much for letting us know to tie this signal off. Had been struggling to get SPI Master working.
