/* 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.
