Increasing the size of the heap

3.1.2: Increasing the size of the heap

The networking tasks allocate a lot of memory. For most applications the heap should be at least 256 kbytes. The amount of memory set aside for the heap can be adjusted by setting the CFLAGS_LD definition as shown below:

CFLAGS_LD += -Wl,--defsym -Wl,HeapSize=0x80000

This sets aside 512 kbytes of memory for the heap.
