I was trying to ping a multicast address on a LWIP-Stack (using the master
code) with LWIP_MULTICAST_PING enabled.
I could see in Wireshark that lwip send an ICMP-echo which linux ping did
not recognize. It seems to me that the problem is that LWIP responses the
ICMP-echo with the multicast-address
We are using LWIP 1.3.2(as ported by TexasInstruments), IAR compiler targeting
a stellaris MCU.
The TI implementation uses a timer tick interrupt 100 times/sec to service the
LWIP stack. No RTOS involved. Our application code also runs on this same
timer tick interrupt so no concurrency issues
Ok, the code is no longer responsive, but I don't have a way to check the
lwip_stats counters because I can't stop the program. I have breakpoints
on the MEM_STATS_INC(err); and MEMP_STATS_INC(err, type); but the software
isn't going there. Where would be a good place to put a breakpoint so I
can
