External Memory

This platform has the following external memories:

+----------------+------------+-------------------------------------+ | Device | Controller | Status | +================+============+=====================================+ | MT48LC16M16A2P | SEMC | Enabled via device configuration | | | | data block, which sets up SEMC at | | | | boot time | +----------------+------------+-------------------------------------+

Supported Features

.. zephyr:board-supported-hw::

.. note::

For additional features not yet supported, please also refer to the :zephyr:board: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.

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

.. zephyr:board-supported-runners::

This board supports 3 debug host tools. Please install your preferred host tool, then follow the instructions in Configuring a Debug Probe_ to configure the board appropriately.

  • :ref:linkserver-debug-host-tools (Default, Supported by NXP)
  • :ref:jlink-debug-host-tools (Supported by NXP)
  • :ref:pyocd-debug-host-tools (Not supported by NXP)

Configuring a Debug Probe

For the RT1024, J47/J48 are the SWD isolation jumpers, J42 is the DFU mode jumper, and J55 is the 10 pin JTAG/SWD header.

.. include:: ../../common/rt1xxx-lpclink2-debug.rst.inc

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 :zephyr:code-sample:hello_world application.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: mimxrt1024_evk :goals: flash

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

.. code-block:: console

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

Debugging

Here is an example for the :zephyr:code-sample:hello_world application.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: mimxrt1024_evk :goals: debug

Open a serial terminal, step through the application in your debugger, and you should see the following message in the terminal:

.. code-block:: console

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