All right people, but since my main goal is to know the exact amount of memory
the lwIP uses, could I just find that out without setting MEMP_MEM_MALLOC to 1,
since it seems that it requires some changes in the kernel itself

This is totally off topic here. The OP has set MEMP_MEM_MALLOC to 1. In this

I'm afraid using MEMP_MEM_MALLOC from interrupt does currently not work: it
will allocate any memory
from the heap,
Hi,
I am not sure with my reply as this area is not so documented.
What I can see in your lwipopts that you use tons of memory for the LwIP heap
but
other defines are way to small
For example:
#define MEMP_NUM_PBUF 16<<< ?
#define MEMP_NUM_UDP_PCB 4
#define MEMP_NUM_TCP_PCB 32
#define

Hello people,
I've been trying to figure out how lwIP uses memory and it's really
important to know exact (or maximum) amount of memory that lwIP uses. I
am using lwIP v1.4.1 with FreeRTOS v8.2.3 on ZYNQ custom board. Right
now, I am working with application
