Hello, I am trying to connect my Xilinx FPGA board (PYNQ-Z2) from TUL with MATLAB and perform hardware in loop simulation on Simulink. However, I am not able to establish connection between FPGA and MATLAB. Could you please guide me what steps do I need to follow to solve this error.

To stop the test, press "Ctrl+C" in the MATLAB console window.

Starting FPGA-in-the-Loop test ...

Generating FPGA programming file ...Passed

Programming FPGA ...Passed

Running FIL simulation ...Failed

Error:Failed to initialize the RTIOStream library.

(a) Xilinx PYNQ-Z2 FPGA board (b) Shorted JTAG Enable Pins

The configuration that I have done on the "New FPGA Board Wizard" for adding customized boards in MATLAB HDL Coder are as shown below.

For you kind reference, I am using

OS: Ubuntu 22.04.5 LTS OS,

FPGA: Xilinx PYNQ-Z2 (from TUL),

MATLAB Version: R2024b

Vivado Version: 2023.2 (ML Standard)

Any suggestions and support would be greatly appreciated. Thank you in advance for your time and support.

Please try the following changes in the FPGA board wizard:

Clock Frequency: 125MHz
Clock Pin number: H16

Also connect the Ethernet port of this board to another Gig Etherner port, e.g. from PC/Switch/Router, using a Ethernet cable, since the Ethernet PHY should be active to generate the PL clock.

Run the validation step again.

The FIL test passed for me. I am using the same jumper setting as you did, and Ethernet is not connected. I've attached my zipped board file. It should be the same as yours anyway.

By the way, I am testing on Windows. There could be driver issues on your Ubuntu. Try manually installing the FTDI driver and Adept runtime.

And can you try on a Windows machine?
