It seems that the "usual" way to get the amount of free RAM that I have always used, i.e.: (int) &v - (__brkval == 0 ? (int) &__heap_start : (int) __brkval) does not work on the Due. Any idea of a method that works on said board?

How to get free RAM size on the Due?

Does this help? Get Free Memory for Teensy 3.0
I believe that Teensy and Due use the same (or similar) malloc code...
(It seems to work on my Due...)
