/* There is an RGB LED on board the SAMA5D2-XULT. The RED component is
|
||||
* driven by the SDHC_CD pin (PA13) and so will not be used. The LEDs are
|
||||
* provided VDD_LED and so bringing the LED low will will illuminated the
|
||||
* LED.
|
||||

|

* ------------------------------ ------------------- -----------------------
|

* SAMA5D2 PIO SIGNAL USAGE
|

* ------------------------------ ------------------- -----------------------
|
||||
* PA13 SDHC_CD_PA13 Red LED
|
||||
* PB5 LED_GREEN_PB5 Green LED
|
||||
* PB0 LED_BLUE_PB0 Blue 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/sam_leds.c. The LEDs are used to encode OS-related
|
||||
* events as follows. Note that only the GREEN LED is used in this case
|
||||
*
|
||||
* SYMBOL Meaning Green 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 if the Green 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.
