Just an info for those who are struggling with lwIP and PTP and NTP (SNTP = "simple" NTP), because I have it running now, after some days with SNTP working only about every 100th time or so.
I'm not a software guy, so that took me some time and nerves... For me, PCB usually stand NOT for protocol control block.
PTP and NTP both use UDP, so make sure that you have enough memory pools for UDP's PCBs,
set MEMP_NUM_UDP_PCB in opt.h
to a higher value than the default 4 (in my case).
Learned a lot about lwIP...
