Does the platform support UDP?

[game11189]

I see that there are UDP-related modules (like udp_stack.sv) in the implementation. But, the platform is not able to receive UDP packets from netcat with port 5001 from my host computer while this works with TCP through hls_recv_krnl.

I also tried disabling TCP-related code inside hls_recv_krnl and used the stream2Ptr HLS function to allow me to see UDP data from s_axis_udp_rx from my host computer. However, the platform gets stuck at q.finish() inside the OpenCL host code when running it on my U50 FPGA.

This is likely because the network module could not receive UDP packets from netcat and thus does not transfer any UDP data to hls_recv_krnl. Is the UDP feature verified?

I recommend capturing the packet using an ILA. For details, see the AMD documentation on enabling kernels for debugging with Chipscope (https://docs.amd.com/r/2024.1-English/ug1393-vitis-application-acceleration/Enabling-Kernels-for-Debugging-with-Chipscope).
