/* The MAX32660-EVSYS board has a single red LED is connected to GPIO P0.13
|
|
* for general user indication. A low value illuminates the LED.
|
|
*
|
|
* This LED is 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/max326_autoleds.c. The LEDs are used to
|
|
* encode OS-related events as follows:
|
|
*
|
|
* ------------------- ----------------------- ------
|
|
* SYMBOL Meaning LED
|
|
* ------------------- ----------------------- ------
|
|
*
|
|
* LED_STARTED 0 NuttX has been started OFF
|
|
* LED_HEAPALLOCATE 0 Heap has been allocated OFF
|
|
* LED_IRQSENABLED 0 Interrupts enabled OFF
|
|
* LED_STACKCREATED 1 Idle stack created ON
|
|
* LED_INIRQ 2 In an interrupt N/C
|
|
* LED_SIGNAL 2 In a signal handler N/C
|
|
* LED_ASSERTION 2 An assertion failed N/C
|
|
* LED_PANIC 3 The system has crashed FLASH
|
|
* LED_IDLE MCU is is sleep mode Not used
|
|
*
|
|
* 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.
