Supporty request.
I am currently implementing a Telnet server on a LPC1768. with LPCopen V1.03 and FreeRTOS.
The telnet server is working fine until the EMAC drops some packets due to heavy traffic on the ethernet link.
I can accept that some packages are dropped and data is lost but the socket locks up and never return from
bytes_recv = lwip_recv(sockfd, &in_char, sizeof(in_char), 0);
With the EMAC-debug option enabled I can see that the pbuf are recovered.
But the recv function never return.
The lwip stacked seesm to hang up in the time out timers :
stmf calling h=tcpip_tcp_timer arg=0
stmf calling h=ip_reass_timer arg=0
The tcp_echo fucntion recovers fine from data loss.
I would like the lwip_recv called to return with the data send after the moment packages are lost. The missing data should not be a problem for my application.
Does somebidy know how to solve this problem?
