print from flash memory broken on DUE?

Hardware Arduino Due
6

Graynomad:
Are you sure

Serial.print("FAIL");

Uses RAM on the Due. I would have thought on the ARM architecture constants are kept in flash anyway and the P macro is redundant.

I'm pretty sure, unless they changed it in the last few versions. My game has a lot of text and the RAM function I run will show FREE RAM go up alot when converting to flash memory storage.

int freeRam(void)
{
  extern int  __bss_end;
  extern int  *__brkval;
  int free_memory;
  if((int)__brkval == 0) {
    free_memory = ((int)&free_memory) - ((int)&__bss_end);
  }
  else {
    free_memory = ((int)&free_memory) - ((int)__brkval);
  }
  return free_memory;
} 

/////called in the upgrade code/regen function like this
void RAM()
{
  clearLCD();
  mySerial.print(F("Free RAM: ")); //debug code
  mySerial.print(freeRam());   //debug code
}
