External Memory
===============
This platform has the following external memories:
+--------------------+------------+-------------------------------------+
| Device | Controller | Status |
+====================+============+=====================================+
| AT25SF128A | FLEXSPI | Enabled via flash configurationn |
| | | block, which sets up FLEXSPI at |

+--------------------+------------+-------------------------------------+
Supported Features
==================
The mimxrt1015_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 mimxrt1015_evk board:
+-----------+------------+-------------------------------------+
| Interface | Controller | Driver/Component |
+===========+============+=====================================+
| NVIC | on-chip | nested vector interrupt controller |
+-----------+------------+-------------------------------------+
| SYSTICK | on-chip | systick |
+-----------+------------+-------------------------------------+
| GPIO | on-chip | gpio |
+-----------+------------+-------------------------------------+
| I2C | on-chip | i2c |
+-----------+------------+-------------------------------------+
| SPI | on-chip | spi |
+-----------+------------+-------------------------------------+
| UART | on-chip | serial port-polling; |
| | | serial port-interrupt |
+-----------+------------+-------------------------------------+
| USB | on-chip | USB device |
+-----------+------------+-------------------------------------+
| ADC | on-chip | ADC |
+-----------+------------+-------------------------------------+
| GPT | on-chip | gpt |
+-----------+------------+-------------------------------------+
| TRNG | on-chip | entropy |
+-----------+------------+-------------------------------------+
The default configuration can be found in
:zephyr_file:`boards/nxp/mimxrt1015_evk/mimxrt1015_evk_defconfig`
Other hardware features are not currently supported by the port.
Connections and I/Os

System Clock
============
The MIMXRT1015 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 MIMXRT1015 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`.
Using LinkServer: :ref:`opensda-daplink-onboard-debug-probe`
------------------------------------------------------------
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.
Linkserver is the default runner. You may also se the ``-r linkserver`` option
with West to use the LinkServer runner.
.. code-block:: console
west flash
west debug
External JLink: :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 J47 and J48 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 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
Flashing
========
Here is an example for the :ref:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: mimxrt1015_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-rc1-1297-g312d75f2459e *****
