USB104 A7 DPTI Transfer SDK Demo Timeout Error

[engineer123]

Hello,

I am attempting to run the "dptiDemo" PC demonstration on a USB104A7 FPGA on Windows 10. I am using all of the DPTI logic files found in the "Adept SDK library - samples - dpti - dptiDemo - logic" directory in my design so that the FPGA can interface with the DPTI ports.

When I compile "dptiDemo.cpp", program the FPGA with my design, and run the executable with the correct parameters specified in the demo README.md, the transfer is not successful. Specifically, the DptiIO() function fails and a case check on DmgrGetLastError() throws this error: "ERROR: data transfer timed out after 30.125000 seconds." I have created ILA probes in my design to monitor the DPTI control bits using Xilinx's hardware manager tool, and can verify that none of the control bits (RX or TX) are falling from 1 to 0 as expected. I am unable to figure out why the transfer might be failing and could use some help.
