Overview

The i.MX RT1064 adds to the industry's first crossover processor series and expands the i.MX RT series to three scalable families. The i.MX RT1064 doubles the On-Chip SRAM to 1MB while keeping pin-to-pin compatibility with i.MX RT1050. This series introduces additional features ideal for real-time applications such as High-Speed GPIO, CAN FD, and synchronous parallel NAND/NOR/PSRAM controller. The i.MX RT1064 runs on the Arm® Cortex-M7® core up to 600 MHz.

External Memory

This platform has the following external memories:

Supported Features

NXP considers the MIMXRT1064-EVK as the superset board for the i.MX RT10xx family of MCUs. This board is a focus for NXP's Full Platform Support for Zephyr, to better enable the entire RT10xx family. NXP prioritizes enabling this board with new support for Zephyr features.

.. zephyr:board-supported-hw::

Shields for Supported Features

Some features in the table above are tested with Zephyr shields. These shields are tested on this board:

:ref:rk043fn02h_ct and :ref:rk043fn66hs_ctg - support the Display interface.
:ref:dvp_fpc24_mt9m114 - supports the CSI video/camera interface.

Connections and I/Os

The MIMXRT1064 SoC has four pairs of pinmux/gpio controllers.

.. note:: In order to use the SPI peripheral on this board, resistors R278, R279, R280 and R281 must be populated with zero ohm resistors

System Clock

The MIMXRT1064 SoC is configured to use SysTick as the system clock source, running at 600MHz.

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 MIMXRT1064 SoC has eight UARTs. LPUART1 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:jlink-debug-host-tools (Supported by NXP)
:ref:linkserver-debug-host-tools (Supported by NXP)
:ref:pyocd-debug-host-tools (Not supported by NXP)

Once the host tool and board are configured, build and flash applications as usual (see :ref:build_an_application and :ref:application_run for more details).

Configuring a Debug Probe

.. note:: * To boot from the QSPI flash, make sure SW7 is set to 0010 and SW5 is set to 0000. * When the device transitions into low power states, the debugger may be unable to access the chip. Use caution when enabling CONFIG_PM, and if the debugger cannot flash the part, see :ref:Troubleshooting RT1064

For the RT1064, J47/J48 are the SWD isolation jumpers, J42 is the DFU mode jumper, and J21 is the 20 pin JTAG/SWD header.

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

See Using J-Link with MIMXRT1060-EVK or MIMXRT1064-EVK_ for more details.

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 J45 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 J41.

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

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

Using SWO

SWO can be used as a logging backend, by setting CONFIG_LOG_BACKEND_SWO=y. Your SWO viewer should be configured with a CPU frequency of 132MHz, and SWO frequency of 7500KHz.

Flashing

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

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: mimxrt1064_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 v1.14.0-rc1 ***** Hello World! mimxrt1064_evk

Debugging

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

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: mimxrt1064_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 v1.14.0-rc1 ***** Hello World! mimxrt1064_evk

.. _Troubleshooting RT1064:

Troubleshooting

If the debug probe fails to connect with the following error, it's possible that the boot header in QSPI flash is invalid or corrupted. The boot header is configured by :kconfig:option:CONFIG_NXP_IMXRT_BOOT_HEADER.

.. code-block:: console

Remote debugging using :2331 Remote communication error. Target disconnected.: Connection reset by peer. "monitor" command not supported by this target. "monitor" command not supported by this target. You can't do that when your target is `exec' (gdb) Could not connect to target. Please check power, connection and settings.

You can fix it by erasing and reprogramming the QSPI flash with the following steps:

#. Set the SW7 DIP switches to ON-OFF-ON-OFF to prevent booting from QSPI flash.

#. Reset by pressing SW9

#. Run west debug or west flash again with a known working Zephyr application.

#. Set the SW7 DIP switches to OFF-OFF-ON-OFF to boot from QSPI flash.

#. Reset by pressing SW9

If the west flash or debug commands fail, and the command hangs while executing runners.jlink, confirm the J-Link debug probe is configured, powered, and connected to the EVK properly.
