NXP MIMXRT1064-EVK
##################

Overview
********

The i.MX RT1064 is the latest addition 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 new 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 at 600 MHz.

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

The mimxrt1064_evk board configuration supports the following hardware
features:

+-----------+------------+-------------------------------------+
| Interface | Controller | Driver/Component                    |
+===========+============+=====================================+
| NVIC      | on-chip    | nested vector interrupt controller  |
+-----------+------------+-------------------------------------+
| SYSTICK   | on-chip    | systick                             |
+-----------+------------+-------------------------------------+
| GPIO      | on-chip    | gpio                                |

| UART      | on-chip    | serial port-polling;                |
|           |            | serial port-interrupt               |
+-----------+------------+-------------------------------------+

The default configuration can be found in the defconfig file:
``boards/arm/mimxrt1064_evk/mimxrt1064_evk_defconfig``

Other hardware features are not currently supported by the port.

Connections and I/Os

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. One is configured for the console and the
remaining are not used.

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

The MIMXRT1064-EVK includes the :ref:`nxp_opensda` serial and debug adapter
built into the board to provide debugging, flash programming, and serial
communication over USB.

To use the Segger J-Link tools with OpenSDA, follow the instructions in the
:ref:`nxp_opensda_jlink` page using the `Segger J-Link OpenSDA V2.1 Firmware`_.
The Segger J-Link tools are the default for this board, therefore it is not
necessary to set ``OPENSDA_FW=jlink`` explicitly when you invoke ``make
debug``.

With these mechanisms, applications for the ``mimxrt1064_evk`` board
configuration can be built and debugged in the usual way (see
:ref:`build_an_application` and :ref:`application_run` for more details).

The pyOCD tools do not yet support this SoC.

Flashing
========

The Segger J-Link firmware does not support command line flashing, therefore
the usual ``flash`` build system target is not supported.
Instead, see the NXP `How to Enable Boot from QSPI Flash App Note
<https://www.nxp.com/docs/en/application-note/AN12108.pdf>`_ for flashing instructions.


Debugging
=========

This example uses the :ref:`hello_world` sample with the
:ref:`nxp_opensda_jlink` tools. Run the following to build your Zephyr
application, invoke the J-Link GDB server, attach a GDB client, and program
your Zephyr application to flash. It will leave you at a GDB prompt.
