Hi,
I'm working with a Zedboard and I have correctly implemented the reference design from here:
http://wiki.analog.com/resources/eval/user-guides/ad-fmcomms1-ebz/reference_hdl
Now I'm interested in creating my own design from the reference design. I have just removed the modules HDMI, spdif, GPIO and modified the DTS file but I still cannot communicate with the board AD-FMCOMMS1-EBZ. I attach the response I get when booting Linaro Linux OS through a SD card:

Welcome to Linaro 12.09 (GNU/Linux 3.6.0 armv7l)
How can I solve the problem of the SPI communication?
How does it affect my design when removing any hardware module from the reference design?
Thanks.
