|
|
* RedLED0 PTA29 (EMIOS1 CH12 / EMIOS2 CH12)
|
|
* GreenLED0 PTA30 (EMIOS1 CH13 / EMIOS2 CH13)

|
|
* BlueLED1 PTE12 (EMIOS1 CH5 / FXIO D8)
|
|

|
|
* An output of '1' illuminates the LED.
|

|
|
* If CONFIG_ARCH_LEDs is defined, then NuttX will control the LED on board

|
* LEDs:
|
|
*
|
|
* SYMBOL Meaning LED state
|
|
* RED GREEN BLUE
|
|
* ---------------- ------------------------ --------------------

* LED_STARTED NuttX has been started OFF OFF OFF
|
|
* LED_HEAPALLOCATE Heap has been allocated OFF OFF ON
|
|
* LED_IRQSENABLED Interrupts enabled OFF OFF ON
|
|
* LED_STACKCREATED Idle stack created OFF 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 FLASH OFF OFF
|
|
* LED_IDLE S32K344 is in sleep mode (Optional, not used)
