The port uses lwIP native IP networking layer. For a list of the 11 bugs fixed, see CHANGELOG. This is because the aim is to present an example of the base lwIP requirement, independent of the configured heap and stack space required for a particular application or target environment. The TCP_MSL is not even defined/compiled for my project, as LWIP_TCP is set to 0 in my lwipopts. So, I create a file with init lwip, , but program is crashed. LWIP_NETCONN_THREAD_SEM_FREE.

There is no guarantee that your forked thread will run and deference the pvParameter before execution returns back to the original thread (which will re-assign clientfd on the next call to accept()) - Joel Cunningham May 14 '15 at 22:09. I have tried to increase and decrease TCPIP_THREAD_STACKSIZE (from 600 to 4k) and MEM_SIZE to 12k in lwIP, with no luck. However the behaviour seems to be the same regardless, it will start fine, with data being received, then it will freeze, often partway through sending data back, until finally the client code on my PC will fail at the write command due to non responding network connection (or something similar).
