/* There are four LEDs on board the SAM4S Xplained board, two of these can be

*
* LED GPIO
* ---------------- -----
* 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
* defined. In that case, the usage by the board port is defined in
* include/board.h and src/up_leds.c. The LEDs are used to encode OS-related
* events as follows:
*
* SYMBOL Meaning LED state
* D9 D10
* ------------------- ----------------------- -------- --------
* LED_STARTED NuttX has been started OFF OFF
* LED_HEAPALLOCATE Heap has been allocated OFF OFF
* LED_IRQSENABLED Interrupts enabled OFF OFF
* LED_STACKCREATED Idle stack created ON OFF
* LED_INIRQ In an interrupt No change
* LED_SIGNAL In a signal handler No change
* LED_ASSERTION An assertion failed No change
* LED_PANIC The system has crashed OFF Blinking
* LED_IDLE MCU is is sleep mode Not used
*
* Thus if D9 is statically on, NuttX has successfully booted and is,
* apparently, running normally. If D10 is flashing at approximately
* 2Hz, then a fatal error has been detected and the system has halted.
