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
*************************

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` (Default, 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::
	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:: ../../../../../../../boards/nxp/common/rt1xxx-lpclink2-debug.rst
   :start-after: rt1xxx-lpclink2-probes

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 :ref:`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 :ref:`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.
