Thanks Bill,
I found another way a second ago (before reading your answer). I just
modified the tcp.h functions back and forth and it worked. Looks like the
tcp.h file wasn't being rebuilt, not sure why, cause I was cleaning and
building...
Not it builds ok. My second problem is also gone. I sent the code on the
AVR32 and tried to ping the address, it didn't work. By debug, I found out
that this hangs:
void
tcpip_init(void (* initfunc)(void *), void *arg)
{
lwip_init();
tcpip_init_done = initfunc;
tcpip_init_done_arg = arg;
mbox = sys_mbox_new(TCPIP_MBOX_SIZE);
#if LWIP_TCPIP_CORE_LOCKING
lock_tcpip_core = sys_sem_new(1);
#endif /* LWIP_TCPIP_CORE_LOCKING */
sys_thread_new(TCPIP_THREAD_NAME, tcpip_thread, NULL,
TCPIP_THREAD_STACKSIZE, TCPIP_THREAD_PRIO);
}
I found in my lwipopts.h file that TCPIP_THREAD_STACKSIZE is defined at 0
and TCPIP_THREAD_PRIO to 1. Not sure why those are the defaults values. I
definitly need to change that I think, but I'm not sure what to put there in
terms of size and priority. Any advice?
Thanks again
