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
D18	User LED
D20	OpenSDA
D21	Reset 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 five user interface switches on the MIMXRT1050 EVK Board:

• SW1: Power Switch (slide switch fir power from J2)

• SW2: ON/OFF Button

• SW3: Power-on Reset button state forces to reset the system power except SNVS domain

• SW9: Reset button

• SW8: User button GPIO5-00

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.

J-Link External Debug Probe

Install the J-Link Debug Host Tools and make sure they are in your search path.

Attach a J-Link 20-pin connector to J21. Check that jumpers J47 and J48 are off (they are on by default when boards ship from the factory) to ensure SWD signals are disconnected from the OpenSDA microcontroller.

Configurations

can

This is an nsh configuration (see below) with added support of CAN driver. FlexCAN3 is chosen as default, the change can be made at System type peripheral selection. Please note that only FlexCAN3 and FlexCAN2 is available on this board.

Bitrate and sample point can be also changed at System type peripheral selection, basic values are 1 MHz for bitrate and 0.80 for sample point. The FlexCAN driver for imxrt runs at 80 MHz clock frequency.

The configuration also includes CAN utilities as candump and cansend.

canfd

This is an nsh configuration (see below) with added support of CAN_FD driver. FlexCAN3 is chosen as default, please note that only FlexCAN3 is capable of providing CAN_FD support.

Bitrate and sample point can be also changed at System type peripheral selection, basic values are 1 MHz for bitrate and 0.80 for sample point for arbitration phase and 4 MHz (bitrate) and 0.90 (sample point) for data phase. The FlexCAN driver for imxrt runs at 80 MHz clock frequency.

The configuration also includes CAN utilities as candump and cansend.

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.

lvgl

Configures the Littlev graphic library (lvgl) demo located under examples/lvgldemo. This configuration needs the optional LCD model RK043FN02H-CT from NXP. The LCD panel comes with the integrated capacitive touchscreen sensor FT5336GQQ connected to the LPI2C1 bus, address 0x38. NuttX support such touchscreen device via the driver ft5x06 (drivers/input/ft5x06.c). At the moment only the polling method is available, the board features an interrupt line connected to the touchscreen sensor IC.

IMXRT1060 MCU provides the integrated LCD driver.

The LCD panel features:

• size 4.3”

• resolution 480×272 RGB

• backlight driver

• dimensions [mm]: 105.5 (W) x 67.2(H) x 4.35(D) Max.

To run the lvgl demo please type “lvgldemo” at nsh prompt:
