Hi there,
I have contacted the digilent support for the same question. They suggested to contact you guys after many discussions. Please see the thread for the history. Thanks a lot.

Hello Iris,
THe MicroZed's PS Pmod port supports the Digilent Pmod interface. Looking at the PmodOLEDrgb, it uses a SPI interface. Try taking a look at our PS SPI PMOD Reference design for how to setup your SPI Controller. If you want to use the PL AXI SPI Controller you will need a breakout carrier card.

Hi Josh,
Thanks for replying.
1) PS SPI. I went through the referecence design and output on the terminal even though I was using PmodOLEDrgb instead of MAX31855 PMOD. But the PmodOLEDrgb_v1.0 IP uses AXI Quad SPI and I don't know how to swap out the AXI Quad SPI driver (PL-PS) with a PS SPI driver in the PmodOLEDrgb IP core. Here is a thread regarding PmodOLEDrgb with Zedboard for my reference.
2)PL AXI SPI: In order to use the PmodOLEDrgb IP core with AXI Quad SPI driver, I am using a microzed io carrier card. I was be able to create the bitstream, program the FPGA, and to launch on the hardware without errors. But I got no output on the OLEDrgb screen. Here is the documentation for the Microzed board. Here is the documentation for the microzed io carrier card. I guess it is a pin assignment problem. I am still trying...

Hi Iris,
So from my understanding you are using the MicroZed + IO Carrier Card in conjunction with the AXI QUAD SPI Controller in the PL? And from what I understand you believe your constraints are incorrect? Please share your constraints and what Pmod connector your using.
Also the issue you are seeing could be and issue with your application aswell.

Hi Josh,
I got it working after fixing the physical constraints. It was an easy fix. Thank you very much for your help.
