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

The mimxrt1010_evk board configuration supports the hardware features listed
below.  For additional features not yet supported, please also refer to the

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

The MIMXRT1010 SoC is configured to use SysTick as the system clock source,
running at 500MHz.

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 MIMXRT1010 SoC has four UARTs. ``LPUART1`` 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).

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.

:ref:`jlink-external-debug-probe`
-------------------------------------------

Install the :ref:`jlink-debug-host-tools` and make sure they are in your search
path.

Attach a J-Link 10-pin connector to J55. Check that jumpers J61 and J62 are
**off** (they are on by default when boards ship from the factory) to ensure
SWD signals are disconnected from the OpenSDA microcontroller.

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 J31 and J32 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

Flashing
========

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

.. zephyr-app-commands::
    :zephyr-app: samples/hello_world
    :board: mimxrt1010_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
