Supported Features

The mimxrt1024_evk board configuration supports the hardware features listed below. For additional features not yet supported, please also refer to the NXP MIMXRT1064-EVK , which is the superset board in NXP’s i.MX RT10xx family. NXP prioritizes enabling the superset board with NXP’s Full Platform Support for Zephyr. Therefore, the mimxrt1064_evk board may have additional features already supported, which can also be re-used on this mimxrt1024_evk board:

Interface	Controller	Driver/Component
NVIC	on-chip	nested vector interrupt controller
SYSTICK	on-chip	systick
FLASH	on-chip	QSPI flash
GPIO	on-chip	gpio
UART	on-chip	serial port-polling; serial port-interrupt

The default configuration can be found in boards/nxp/mimxrt1024_evk/mimxrt1024_evk_defconfig

Other hardware features are not currently supported by the port.

Connections and I/Os

The MIMXRT1024 SoC has five pairs of pinmux/gpio controllers.

System Clock

The MIMXRT1024 SoC is configured to use SysTick as the system clock source, running at 500MHz.

When power management is enabled, the 32 KHz low frequency oscillator on the board will be used as a source for the GPT timer to generate a system clock. This clock enables lower power states, at the cost of reduced resolution

Serial Port

The MIMXRT1024 SoC has eight UARTs. One is configured for the console and the remaining are not used.

Programming and Debugging

Build and flash applications as usual (see Building an Application and Run an Application for more details).

Configuring a Debug Probe

A debug probe is used for both flashing and debugging the board. This board is configured by default to use the OpenSDA DAPLink Onboard Debug Probe, however the pyOCD Debug Host Tools do not yet support programming the external flashes on this board so you must reconfigure the board for one of the following debug probes instead.

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 10-pin connector to J55. 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.

Configuring a Console

Regardless of your choice in debug probe, we will use the OpenSDA microcontroller as a usb-to-serial adapter for the serial console. Check that jumpers J50 and J46 are on (they are on by default when boards ship from the factory) to connect UART signals to the OpenSDA microcontroller.

Connect a USB cable from your PC to J23.

Use the following settings with your serial terminal of choice (minicom, putty, etc.):

Speed: 115200
Data: 8 bits
Parity: None
Stop bits: 1

Flashing

Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b mimxrt1024_evk samples/hello_world
west flash

Open a serial terminal, reset the board (press the SW9 button), and you should see the following message in the terminal:

***** Booting Zephyr OS v2.4.0-rc1 *****
Hello World! mimxrt1024_evk
