I have a Avnet microZed Board. It is running FreeRTOS 8.2.1. Code is running lwIP_Demo which can be downloaded from the FreeRTOS website. I wish to use a broadcast UDP from a host machine ( ie a PC) and have the microZed respond over UDP with its IP address and some additional information. It is using code based on mDNS Responder. I cannot get the receive code on the microZed to respond to the UDP packets that I am sending. I have working code that sends a UDP packet from the microZed, and is properly received on the PC, but I wish to switch the direction, and have the PC send the packet first, and have the microZed respond. I need help getting the receive of UDP working on the microZed. I would upload my code snippet, and would like to get some suggestions to try initially. Since this project requires specific hardware it would be difficult to test on your end, but if you happen to have a microZed and can verify the code is working that is a plus.
