My design has 3 microblaze CPU, two for running 802.11 protocol, one for run ad9361 (fccomms3) driver
I use the clk_out (40MHz) of the ad9361 as the protocol system clk.
I use the fpga IP core from the below
and I didn't use the axi_dmac.
I can transmit my data and receive very well
Now my question is,
I make my own spi IP(in order to run initialization by hardware), but I just don't connect and wire to the design
and the driver initialization failed
(red mark means I add some xil_printf to print information)
the difference is I add a IP into the design but the whole system will not use it and it will not connect to any other IP
the other question is that the timing constraint of ad9361, I think ot might be add to .ucf
can some body teach me how to add?
