Now I'm trying to add QSPI interface that can connect to the JA Pmod connector but can't seem to figure it out. I have an ADC that implements an SPI interface with 4 data outputs that should work with a QSPI interface.
I can add the "axi_quad_api" IP to my diagram and it connects most pieces properly. It can't find outputs to connect to. I tried renaming the output connection to "ja" (from "SPI_0_0") to use what I found in the "board.xml" file, but I still get the same "IO placement is infeasible" error.
Is it possible to do what I'm trying to do?
If so, does anyone know what I'm doing wrong?
Or at least know where I can look for a description of this kind of process (adding any IP, connecting to any output pins)?
Thanks!
P.S. I am also OK simplifying the initial process to just use standard SPI to figure out the flow of adding IP and connecting it up, then later updating it to QSPI.

Hello,
I've followed the instructions here:
https://reference.digilentinc.com/learn/programmable-logic/tutorials/pmod-ips/start
to get a basic Microblaze project functioning. I can successfully program the device with the basic project (although had to figure out the UART bit since that doesn't seem to be on there).
Now I'm trying to add QSPI interface that can connect to the JA Pmod connector but can't seem to figure it out. I have an ADC that implements an SPI interface with 4 data outputs that should work with a QSPI interface.
