+/* The EFM32 Giant Gecko Start Kit has two yellow LEDs marked LED0 and LED1.
+ * These LEDs are controlled by GPIO pins on the EFM32. The LEDs are
+ * connected to pins PE2 and PE3 in an active high configuration:
+ *
+ * ------------------------------------- --------------------
+ * EFM32 PIN BOARD SIGNALS
+ * ------------------------------------- --------------------
+ * E2/BCK_VOUT/EBI_A09 #0/ MCU_PE2 UIF_LED0
+ * TIM3_CC2 #1/U1_TX #3/ACMP0_O #1
+ * E3/BCK_STAT/EBI_A10 #0/U1_RX #3/ MCU_PE3 UIF_LED1
+ * ACMP1_O #1
+ * ------------------------------------- --------------------
+ *
+ * All LEDs are grounded and so are illuminated by outputting a high
+ * value to the LED.
+ *
+ * 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/efm32_autoleds.c. The LEDs are used to
+ * encode OS-related events as follows:
+ *
+ * SYMBOL Meaning LED state
+ * LED0 LED1
+ * ------------------- ----------------------- -------- --------
+ * 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 STM32 is is sleep mode Not used
+ *
+ * Thus if LED0 statically on, NuttX has successfully booted and is,
+ * apparently, running normally. If LED1 is flashing at approximately
+ * 2Hz, then a fatal error has been detected and the system has halted.
