* ---------------- -----
* D9 Yellow LED PC10
* D10 Yellow LED PC17

* Both can be illuminated by driving the GPIO output to ground (low).

* These LEDs are not used by the board port unless CONFIG_ARCH_LEDS is

* LED_STARTED NuttX has been started OFF OFF
* LED_HEAPALLOCATE Heap has been allocated OFF OFF
