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.
Using J-Link¶
Install the J-Link Debug Host Tools and make sure they are in your search path.
There are two options: the onboard debug circuit can be updated with Segger J-Link firmware, or J-Link External Debug Probe can be attached to the EVK. 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
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 :kconfig:`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:
Set the SW7 DIP switches to ON-OFF-ON-OFF to prevent booting from QSPI flash.
Reset by pressing SW9
Run
west debugorwest flashagain 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. See Using J-Link for more details.
