Arduino Due, IDE Compiler NOT SHOWING MEMORY USAGE

[matiaskenig]

When compile in Arduino IDE, the GLOBAL MEMORY USAGE are showed in all versions EXCEPT WHEN DUE, why????

Indeed, it's ONLY shown on AVR 😄 Jokes apart, the RAM usage calculation is much more useful on AVR boards, since its quantity is very limited. On ARM boards with 32KB+ SRAM it's quite difficult to trigger memory-related bugs. If you want to add it, the right place is https://github.com/arduino/Arduino/blob/master/hardware/arduino/sam/platform.txt#L92 , and you can use https://mcuoneclipse.com/2013/04/14/text-data-and-bss-code-and-data-size-explained/ and https://github.com/arduino/Arduino/blob/master/hardware/arduino/avr/platform.txt#L81 as inspiration
