NXP MIMXRT1064-EVK

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.

System Clock

The MIMXRT1064 SoC is configured to use the 24 MHz external oscillator on the board with the on-chip PLL to generate a 600 MHz core clock.

Serial Port

The MIMXRT1064 SoC has eight UARTs. LPUART1 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.

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

Flashing

Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b mimxrt1064_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 v1.14.0-rc1 *****
Hello World! mimxrt1064_evk

Debugging

Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b mimxrt1064_evk samples/hello_world
west debug

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

***** Booting Zephyr OS v1.14.0-rc1 *****
Hello World! mimxrt1064_evk

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 CONFIG_NXP_IMX_RT_BOOT_HEADER.

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:

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

  2. Reset by pressing SW9

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

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

  5. 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. See Using J-Link for more details.
