* 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_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 normally. If D10 is flashing at approximately
|
||||||
|
* 2Hz, then a fatal error has been detected and the system has halted.
