|
||||
* ---------------- -----
|
||||
* D9 Yellow LED PC10
|
||||
* D10 Yellow LED PC17
|
||||
*
|
||||
* Both can be illuminated by driving the GPIO output to ground (low).
|
||||
*
|
||||
* 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/up_leds.c. The LEDs are used to encode OS-related
|
||||
* events as follows:
|
||||
*
|
||||
* SYMBOL Meaning LED state
|
||||
* D9 D10
|
||||
* ------------------- ----------------------- -------- --------
|
||||
* 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 MCU is is sleep mode Not used
|

*
|

* Thus if D9 is statically on, NuttX has successfully booted and is,
|

* apparently, running normmally. If D10 is flashing at approximately
|
