Hi,
I used the example code, lwIP UDP perf Client, to do the UDP sending performance test on the zynq ultrascale+MPSOC platform. Sometimes, I encountered the issue, where it showed the sending performace is more than 5Gbps but it did not realy send any data to server. In the example code, if calling the function, err = udp_send(pcb[i], packet), without returning error, it means sending is successful. I sometimes encountered that I called the function without returnning error after finishing sgmii auto-negotiation, but it didn't realy send any data to server.
I hope to know how to solve the issue.
Thanks,
Best regards,
Philip Chen
