Hi, I am trying to implement the echo server example code that is available in the lwip wiki in Tiva C series 129X. But I am having connectivity issues. The server code does not reach the lwip accept method in tcp raw api. I have tested the code without connecting to a router/switch, i.e directly connected the launchpad and the laptop using a ethernet cable. I have assigned a static ip to the launchpad as well the laptop. I also want to implement a modbus slave server using the echo server example, later on. How do I debug the interrupt handler problems? Thank in advance.
