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.
