/* LEDs
|
|
*
|
|
* A single LED is available driven by USR_DEF_RED_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/imx_autoleds.c. The LEDs are used to encode
|
|
* OS-related events as follows:
|
|
*
|
|
* ------------------- ----------------------- ------
|
|
* SYMBOL Meaning 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 is 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.
