I just get two Fmcomms3 and I use them with the Zynq ZC702.
I've try the quick start guide but I didn't get anything on the IIO scope. As you can see on the following picture there is an error with the SPI bus and the clock when I boot on the SD card with the UART terminal.
In the IIO scope the only device that I've found is an xadc.
Do you have an idea? Is there something to do to synchronize the daughterboard and the motherboard?
