Hi,
during a test we ran into a serious issue and I'd be more than happy to get
some hints how to track that down.
In a test scenario we ran a ping test with various byte sizes via the PPP
netif. With exactly the ping packet size of 92 bytes, our LwIP task crashes
repeatedly into an assert:
15.05.17 11:07:17 ASSERT:
C:/Projekte/TMO-100/Libraries/lwIP/src/core/pbuf.c:888:p_to != NULL
The line where this happens is line 888 in pbuf.c:
if (offset_to == p_to->len) {
/* on to next p_to (if any) */
offset_to = 0;
p_to = p_to->next;
LWIP_ERROR("p_to != NULL", (p_to != NULL) || (p_from == NULL) , return
ERR_ARG;);
}
It's strange that this does not happen if the ping comes via the ETH netif, it
only occurs via the PPP netif.
Any ideas where to start debugging is welcome ;-)
Thanks,
