[lwip-users] MEM_SIZE

[Giuseppe Modugno]

I was experimenting with lwip memory allocator. I defined:

#define MEM_LIBC_MALLOC  0
#define MEM_USE_POOLS      0
#define MEM_SIZE  (32 * 1024)
#define LWIP_RAM_HEAP_POINTER  ( (void *)0x2007C000 )

I'm using LPC1768 that has a 32kB SRAM block starting from address 
0x2007C000. However I have a Hard Fault error during mem_init(), because 
ram_end is initialized to 0x2007C000 + (32*1024), that is over the 
available memory.

So MEM_SIZE should be smaller than available heap memory.
