/* LEDs
*
* A single LED is available driven by PA13.
*
* 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/sam_autoleds.c. The LEDs are used to encode
* OS-related events as follows:
*
* ------------------- ----------------------- ------
* SYMBOL Meaning LED
* ------------------- ----------------------- ------
* LED_STARTED NuttX has been started OFF
* LED_HEAPALLOCATE Heap has been allocated OFF
* LED_IRQSENABLED Interrupts enabled OFF
* LED_STACKCREATED Idle stack created ON
* LED_INIRQ In an interrupt N/C
* LED_SIGNAL In a signal handler N/C
* LED_ASSERTION An assertion failed N/C
* LED_PANIC The system has crashed FLASH
*
* Thus is LED is statically on, NuttX has successfully booted and is,
* apparently, running normally. If LED is flashing at approximately
* 2Hz, then a fatal error has been detected and the system has halted.
