I am using the demo design from the No-OS repository for the zedboard and FMCOMMS3 board. I am using the wiki user guide and I managed to get the design compiled and running, but I am having trouble understanding generally how the software design works. I need to know
1. Where is the data to be transmitted to the DAC's on the FMCOMMS3 read from? In other words, how do I write to the FMCOMMS3?
2. Where is the data received from the ADC's on the FMCOMMS3 written to? In other words, how do I read from the FMCOMMS3?
Is there any general documentation that overviews how the No-OS software fits together where I could find this kind of information?
