/* LEDs: There are three LEDs on board the SAM4L Xplained Pro board:
|
|
* The EDBG controls two of the LEDs, a power LED and a status LED.
|
|
* There is only one user controllable LED, a yellow LED labeled LED0 near
|
|
* the SAM4L USB connector.
|
|
*
|
|
* This LED is controlled by PC07 and LED0 can be activated by driving the
|
|
* PC07 to GND.
|
|
*
|
|
* When CONFIG_ARCH_LEDS is defined in the NuttX configuration, NuttX will
|
|
* control LED0 as follows:
|
|
*
|
|
* SYMBOL Meaning LED0
|
|
* ------------------- ----------------------- ------
|
|
* 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 LED0 is statically on, NuttX has successfully booted and is,
|
|
* apparently, running normmally. If LED0 is flashing at approximately
|
|
* 2Hz, then a fatal error has been detected and the system has halted.
