LEDs and buttons

LEDs

There are three LED status indicators located on the Board. The functions of these LEDs include:

Pin

Description

LED1

Power Supply

LED2

User LED

LED3

5V Power ON

Only a single LED (LED2) is under software control. It connects to GPIO_AD_B0_08.

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/imxrt_autoleds.c. The LED is 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 if the LED is statically on, NuttX has successfully booted and is, apparently, running normally. If the LED is flashing at approximately 2Hz, then a fatal error has been detected and the system has halted.

Buttons

There are no buttons in the Board:

Configurations

nsh

Configures the NuttShell (nsh) located at examples/nsh. This NSH configuration is focused on low level, command-line driver testing. Built-in applications are supported, but none are enabled. This configuration does not support a network.
