Thanks for your help.
In my case pbuf_alloc( PBUF_RAW, pNBuf->length, PBUF_POOL) is calling
memp_malloc(). It worked on another project slightly different than the one
I'm trying to debug. The other project that works has different memory map
settings and don't use standard libraries, but lwipopts.h and opt.h are the
same.
I'll will try calling pbuf_alloc() with PBUF_RAM so it'll call mem_malloc.

That LWIP_ERROR is checking that memp_malloc() was called with a valid memory
type. It isn't related to MEMP_OVERFLOW_CHECK.
Whatever is calling memp_malloc() has specified an illegal value for the
memory pool from which an allocation is to occur. Perhaps something is trying
to call this function with the number of bytes to allocate? If so, the caller
should use mem_malloc() instead.
You should be able to spot the problem if you can set a breakpoint on the
LWIP_ERROR. What value is 'type' and who called memp_malloc() with the bogus
argument?

Subject: [lwip-users] Fw: problem in memp_alloc()
Hi all,
I have made a new lwIP 1.3.0 project (with no OS) based on a project that
runs well. Now this new project fails to initialize. I got a system assert in
memp_malloc(): LWIP_ERROR("memp_malloc: type < MEMP_MAX", (type < MEMP_MAX),
return NULL;)
I did'nt change any options in files opt.h or lwiopts.h, and my settings
has always been to define MEMP_OVERFLOW_CHECK 0.
any idea of option I could do to debug that?
I've tried to define MEMP_OVERFLOW_CHCK to 1 and to 2, but the cpu hangs
somewhere in memp_overflow_check_all().(But this problem is not lwip related).
