Re: [lwip-users] Getting started with lwIP on a NON-SYS platform

[Angel CODREAN]

Hey guys,

While trying to make lwIP work, with a simple ping I have problems with it. Trying to debug it I noticed that I cannot allocate memory using memp_alloc. The problem that I have is that memp_tab[]  is an array with NULL elements.

I tried to play with the lwipopts.h parameters making sure that I have enough buffs, I checked if I free properly to prevent leakage but I also have the problem in the very begining.

I attached the files that might help you help me:D

Best regards,

Angel C

That simply means you are running out of memory in one of the pools. Either you memory is (configured) too small or you are leaking (i.e. not freeing) memory somewhere.
