Serial Console

Virtual console port provided by OpenSDA:

UART1_TXD	GPIO_AD_B0_12	LPUART1_TX
UART1_RXD	GPIO_AD_B0_13	LPUART1_RX

Arduino RS-232 Shield:

J22	D0	UART_RX	GPIO_AD_B1_07	LPUART3_RX
J22	D1	UART_TX	GPIO_AD_B1_06	LPUART3_TX

LEDs and buttons

LEDs

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

Pin	Description
D3	Power Supply
D15	Reset LED
D16	OpenSDA
D18	User LED

Only a single LED, D18, is under software control. It connects to GPIO_AD_B0_09 which is shared with JTAG_TDI and ENET_RST

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 four user interface switches on the MIMXRT1050 EVK Board:

• SW1: Power Switch (slide switch)

• SW2: ON/OFF Button

• SW3: Reset button

• SW8: User button

Only the user button is available to the software. It is sensed on the WAKEUP pin which will be pulled low when the button is pressed.

Configurations

knsh

This is identical to the nsh configuration below except that NuttX is built as a protected mode, monolithic module and the user applications are built separately. For further information about compiling and running this configuration please refer to imxrt1064-evk documentation.

netnsh

This configuration is similar to the nsh configuration except that is has networking enabled, both IPv4 and IPv6. This NSH configuration is focused on network-related testing.

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.
