Core-dump - mg_lwip_ev_mgr.c: No such file or directory

Hi all,

I’m trying to make sense out of this core dump I captured:

Dump contains FreeRTOS task info
Loaded core dump from last snippet in  /core

I’m not sure if it’s saying the mgr was <optimized out> or that it broke because it could not find mg_lwip_ev_mgr.c

Any help/suggestions would be appreciated:

Thanks

Thanks @nliviu, I think I see my error in how I was reading the messages.

I see line 59 called out which is mg_if_can_recv_cb(nc);
Doing some googling I found this post where you recommended a build var, I’ll give that a try and see if I get any better performance.

Thanks.
