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.

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

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

Configuring a Debug Probe

Note

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 Troubleshooting

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.

  1. Install the LinkServer Debug Host Tools and make sure they are in your search path.

  2. To update the debug firmware, please follow the instructions on MIMXRT1064-EVK Debug Firmware

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 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.
