Hi Edwin, > Can someone shed some light on how to solve this issue?
If you want to chase it yourself I can recommend adding some LWIP_DEBUGF() and some LWIP_ASSERTS() in the netconn code, trying to locate some obvious bugs or flaws. I see the FreeRTOS port doesn't provide the LWIP_PLATFORM_DIAG() and LWIP_PLATFORM_ASSERT() macros that are needed for this (in cc.h). Maybe you could ask the FreeRTOS porters about this omission. Also they should update to at least 1_1_1. If your board has some terminal / serial line that can output printf's you could define these macro's to printf. If not, then you may need to improvise your own printf over ethernet (can be very helpfull since you get a good idea of order of events). Sorry, I don't have time to read your trace in detail, but I clearly see some TCP checksum failures, there must be a serious software or hardware malfunction somewhere.
