Richard, first of all, thanks for your quick response.
What I forgot to mention is that application doesn't crash at the very
beginning, it actually works for some time how it should work and than
suddenly crashes. I suppose that problem you mention would manifest
itself right from the beginning, when XEmacPs_IntrHandler is called for
the first time? Moreover, I thought that lwIP doesn't use standard C
malloc() and free() functions (if you are talking about those), but have
custom heap-based function mem_malloc(), UNLESS we set option
MEM_LIBC_MALLOC to 1 , which I haven't done.
Mistake on my part - I thought you were using malloc and free.
You said the assert gets hit. The one on line queue.c:1224 guards
against the use of a mutex in an interrupt and the one in port.c against
a non-interrupt safe function being called from an interrupt - so if a
mutex is being used in an interrupt, the deferred handler bit of my last
email would still hold true.
Regards,
Richard.
