NXP MIMXRT1060-EVK
##################

Overview
********

The i.MX RT1060 adds to the industry's first crossover
processor series and expands the i.MX RT series to three scalable families.

The i.MX RT1060 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 RT1060 runs on the
Arm® Cortex-M7® core up to 600 MHz.

Supported Features
==================

The mimxrt1060_evk board configuration supports the hardware features listed
below.  For additional features not yet supported, please also refer to the
:ref:`mimxrt1064_evk` , which is the superset board in NXP's i.MX RT10xx family.
NXP prioritizes enabling the superset board with NXP's Full Platform Support for
Zephyr.  Therefore, the mimxrt1064_evk board may have additional features
already supported, which can also be re-used on this mimxrt1060_evk board:

.. 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 MIMXRT1060 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 MIMXRT1060 SoC has eight UARTs. ``LPUART1`` is configured for the console,
``LPUART3`` for the Bluetooth Host Controller Interface (BT HCI), and the
remaining are not used.

Programming and Debugging
*************************

Build and flash applications as usual (see :ref:`build_an_application` and
:ref:`application_run` 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 :ref:`opensda-daplink-onboard-debug-probe`,
however the :ref:`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 LinkServer:

        1. Install the :ref:`linkserver-debug-host-tools` and make sure they are in your search path.
        2. To update the debug firmware, please follow the instructions on `MIMXRT1060-EVK Debug Firmware`

.. _Using J-Link RT1060:

Using J-Link
---------------------------------

Install the :ref:`jlink-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 :ref:`jlink-external-debug-probe` can be attached to the
EVK. See `Using J-Link with MIMXRT1060-EVK or MIMXRT1064-EVK`_ or
`Using J-Link with MIMXRT1060-EVKB`_ 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: mimxrt1060_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! mimxrt1060_evk

Debugging
=========

Here is an example for the :ref:`hello_world` application.

.. zephyr-app-commands::
   :zephyr-app: samples/hello_world
   :board: mimxrt1060_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! mimxrt1060_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:option:`CONFIG_NXP_IMX_RT_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. See :ref:`Using J-Link RT1060` for more details.

Experimental ENET Driver
========================

Current default ethernet driver is eth_mcux, with binding `nxp,kinetis-ethernet`. There is a new
driver with binding `nxp,enet`, which is experimental and undergoing development, but will have
enhanced capability, such as not hardcoding code for only one phy in the driver like eth_mcux.

To build for this EVK with the new driver, include the experimental overlay to west build with
the option `-DEXTRA_DTC_OVERLAY_FILE=nxp,enet-experimental.overlay`.
