Hi,
I am a software engineer from China. I am working on a set top box
project, in which we use TCP/IP protocol to transmit control command and user
data. I've ported the LWIP (1.1.0) to our platform (OS20 of ST
Microelectronics) and it can work basically.
But I encountered a problem currently. When a large amount of data are
transmitting, the program is very easy to crash at an assertion in tcp_receive:
if (pcb->snd_queuelen != 0) {
LWIP_ASSERT("tcp_receive: valid queue length",
pcb->unacked != NULL || pcb->unsent != NULL);
}
I've checked the bug list on website:
http://savannah.nongnu.org/projects/lwip,
But I didn't find any report about this problem. I wrote application to use raw
API directly.
Can anyone give me some hints?
Best regards
Jeffery Du
