Hello,

I'm trying to write a tcp server using that interface for a blackfin board. An other application which use the socket interface works well. 
The issue happens when I complete the accept_callback function, calling the function 
 tcp_accepted (newpcb) ,with newpcb the argument passed to the callback.
The function shows the message:
Assertion "pcb->state == LISTEN (called for wrong pcb?)" failed at line 141 in ..\..\App\ListenThread.cpp, after that the system go into Kernel Panic.
What I seen is that the newpcb->state is in ESTABLISHED not LISTENING.

Thank you for helps.

Best regards
