Hi,
We've started our first lwIP project, following the instructions on
http://lwip.wikia.com/wiki/Raw/TCP to create our high level functions and
taking the device level IRQ functions and ethernetif.c from the SDK for our
chip (Freescale Kinetis K60)
Although we appear to have set things up correctly - we can send & receive
requests - the TCP pbufs pool is not running out and it looks like they are not
being freed after the receive has been processed.
I can see in tcp_recv_null in tcp.c that pbuf_free(p); is called after
tcp_recved(pcb, p->tot_len); but I can't find any info about freeing the pbufs
in the wiki via either pbuf_free or pbuf_free_callback.
Should I be calling pbuf_free/ pbuf_free_callback in our receive callback or is
this supposed to be handled elsewhere?
Thanks,
Gabriel
