This seems to be some memory management/conflict problem between
FreeRTOS, lwIP and AVR
Will report if I can pin-point the problem

Subject: [lwip-users] DHCP OK but TCP not?

Hi there,
I have been developing my project using static IP and every works
great, now I wanted to turn on DHCP
Bad news, DHCP got the IP assigned, but I can't connect to it via TCP
anymore (UDP works fine), and the only difference in codes are
if (DHCP){
//This gets the IP, but I can't open via TCP
IP4_ADDR( &xIpAddr,0,0,0,0 );
IP4_ADDR( &xNetMask,255,255,255,0 );
IP4_ADDR( &xGateway,0,0,0,0 );
netif_add( &MACB_if, &xIpAddr, &xNetMask, &xGateway,
NULL, ethernetif_init, tcpip_input );
netif_set_default( &MACB_if );
dhcp_start(&MACB_if);
}
else{
//This works perfectly
IP4_ADDR( &xIpAddr,myIP[0],myIP[1],myIP[2],myIP[3]);
IP4_ADDR( &xNetMask,255,255,255,0 );
IP4_ADDR( &xGateway,0,0,0,0 );
netif_add( &MACB_if, &xIpAddr, &xNetMask, &xGateway,
NULL, ethernetif_init, tcpip_input );
netif_set_default( &MACB_if );
netif_set_up( &MACB_if );
}
......
//If DHCP is used, it will not returned from this call
clientfd = lwip_accept(lSocket, (struct sockaddr*)&client_addr,
(socklen_t)&addrlen);
I am using lwip 1.32 on AVR32. Is there a known bug like this?
Thanks for your time!
