NXP MIMXRT1170-EVK/EVKB
#######################

Overview
********

The dual core i.MX RT1170 runs on the Cortex-M7 core at 1 GHz and on the Cortex-M4
at 400 MHz. The i.MX RT1170 MCU offers support over a wide temperature range
and is qualified for consumer, industrial and automotive markets. Zephyr
supports the initial revision of this EVK, as well as rev EVKB.

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

NXP considers the MIMXRT1170-EVK as the superset board for the i.MX RT11xx
family of MCUs.  This board is a focus for NXP's Full Platform Support for
Zephyr, to better enable the entire RT11xx family.  NXP prioritizes enabling
this board with new support for Zephyr features. Note that this table
covers two boards: the RT1170 EVK (`mimxrt1170_evk//cm7/cm4`), and
RT1170 EVKB (`mimxrt1170_evk@B//cm7/cm4`)

Dual Core samples

+----------+------------------+-----------------------+
| ocram2   | 0x200C0000[512K] | Mailbox/shared memory |
+----------+------------------+-----------------------+

Only the first 16K of ocram2 has the correct MPU region attributes set to be
used as shared memory

System Clock
============

The MIMXRT1170 SoC is configured to use SysTick as the system clock source,
running at 996MHz. When targeting the M4 core, SysTick will also be used,
running at 400MHz

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 MIMXRT1170 SoC has 12 UARTs. One is configured for the console 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).

Building a Dual-Core Image
==========================
Dual core samples load the M4 core image from flash into the shared ``ocram``
region. The M7 core then sets the M4 boot address to this region. The only
sample currently enabled for dual core builds is the ``openamp`` sample.
To flash a dual core sample, the M4 image must be flashed first, so that it is
written to flash. Then, the M7 image must be flashed. The openamp sysbuild
sample will do this automatically by setting the image order.

The secondary core can be debugged normally in single core builds
(where the target is ``mimxrt1170_evk/mimxrt1176/cm4``). For dual core builds, the
secondary core should be placed into a loop, then a debugger can be attached
(see `AN13264`_, section 4.2.3 for more information)

Configuring a Debug Probe
=========================

A debug probe is used for both flashing and debugging the board. The on-board
debugger listed below works with the LinkServer runner by default, or can be
reprogrammed with JLink firmware.
- MIMXRT1170-EVKB: :ref:`mcu-link-cmsis-onboard-debug-probe`
- MIMXRT1170-EVK:  :ref:`opensda-daplink-onboard-debug-probe`

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

JLink is the default runner for this board.  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 MIMXRT1170-EVKB`_ or
`Using J-Link with MIMXRT1160-EVK or MIMXRT1170-EVK`_ for more details.

Using LinkServer
----------------

Known limitations with LinkServer and these boards include:
- ``west debug`` does not yet work correctly, and the application image is not
properly written to the memory.  `NXP MCUXpresso for Visual Studio Code`_
can be used to debug Zephyr applications with LinkServer.
- ``west flash`` will not write images to non-flash locations. The flash
command only works when all data in the image is written to flash memory
regions.

Install the :ref:`linkserver-debug-host-tools` and make sure they are in your
search path.  LinkServer works with the default CMSIS-DAP firmware included in
the on-board debugger.

Use the ``-r linkserver`` option with West to use the LinkServer runner.

.. code-block:: console

   west flash -r linkserver

Alternatively, pyOCD can be used to flash and debug the board by using the
``-r pyocd`` option with West. pyOCD is installed when you complete the
:ref:`gs_python_deps` step in the Getting Started Guide. The runners supported
by NXP are LinkServer and JLink. pyOCD is another potential option, but NXP
does not test or support the pyOCD runner.

Configuring a Console
=====================

We will use the on-board debugger
microcontroller as a usb-to-serial adapter for the serial console. The following
jumper settings are default on these boards, and are required to connect the
UART signals to the USB bridge circuit:
- MIMXRT1170-EVKB: JP2 open (default)
- MIMXRT1170-EVK:  J31 and J32 shorted (default)

Connect a USB cable from your PC to the on-board debugger USB port:
- MIMXRT1170-EVKB: J86
- MIMXRT1170-EVK:  J11

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 :ref:`hello_world` application.

Before powering the board, make sure SW1 is set to 0001b

.. zephyr-app-commands::
   :zephyr-app: samples/hello_world
   :board: mimxrt1170_evk/mimxrt1176/cm7
   :goals: flash

Power off the board, and change SW1 to 0010b. Then power on the board and
open a serial terminal, reset the board (press the SW4 button), and you should
see the following message in the terminal:

.. code-block:: console

   ***** Booting Zephyr OS v3.4.0-xxxx-xxxxxxxxxxxxx *****
   Hello World! mimxrt1170_evk

Debugging
=========

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

.. zephyr-app-commands::
   :zephyr-app: samples/hello_world
   :board: mimxrt1170_evk/mimxrt1176/cm7
   :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 v3.4.0-xxxx-xxxxxxxxxxxxx *****

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`.
