RTOS/TM4C1294NCPDT: Ethernet lock up if link is intermittent

Part Number: TM4C1294NCPDT


Tool/software: TI-RTOS

I am using the TM4C1294NCPDT with TI-RTOS and Code Composer Studio 6.

My application uses the Ethernet port for TCP and UDP communication with devices over a wireless link.

The issue I run into is when the link becomes marginal and the Ethernet data get interrupted the processor will hang up and will force a reboot.

I suspect the TCP/IP stack may be getting bad data and freezing up.  Not sure, just a guess.

I have set timeouts for the TCP and UDP sockets but I believe that is for a no connection timeout.

Is there a way to break out of a TCP/UDP communication session if the link drops mid way?

Thanks,

Sam V
