+---------------+-----------------+---------------------------+
.. note::
In order to use the SPI peripheral on this board, resistors R350, R346,
and R360 must be populated with zero ohm resistors.
System Clock
============
The MIMXRT1040 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 MIMXRT1040 SoC has eight UARTs. ``LPUART1`` is configured for the console,
``LPUART3`` for the Bluetooth Host Controller Interface (BT HCI),
and the remaining UARTs are not used.
Fetch Binary Blobs
==================
The board Bluetooth/WiFi module requires fetching some binary blob files, to do
that run the command:
.. code-block:: console
west blobs fetch hal_nxp
.. note:: Only Bluetooth functionality is currently supported.
Programming and Debugging
*************************
This board supports 3 debug host tools. Please install your preferred host
tool, then follow the instructions in `Configuring a Debug Probe`_ to
configure the board appropriately.
* :ref:`jlink-debug-host-tools` (Default, Supported by NXP)
* :ref:`linkserver-debug-host-tools` (Supported by NXP)
* :ref:`pyocd-debug-host-tools` (Not supported by NXP)
Once the host tool and board are configured, build and flash applications
as usual (see :ref:`build_an_application` and :ref:`application_run` for more
details).
Configuring a Debug Probe
=========================
For the RT1040, J9/J10 are the SWD isolation jumpers, J12 is the DFU
mode jumper, and J2 is the 20 pin JTAG/SWD header.
.. include:: ../../common/rt1xxx-lpclink2-debug.rst
:start-after: rt1xxx-lpclink2-probes
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 J11 and J13 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 J1.
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: mimxrt1040_evk
:goals: flash
Open a serial terminal, reset the board (press the SW1 button), and you should
see the following message in the terminal:
.. code-block:: console
***** Booting Zephyr OS Booting Zephyr OS build v3.3.0-rc3-66 *****
Hello World! mimxrt1040_evk
Debugging
=========
Here is an example for the :ref:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: mimxrt1040_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 Booting Zephyr OS build v3.3.0-rc3-66 *****
Hello World! mimxrt1040_evk
Troubleshooting
===============
USER_LED D8
-----------
The MIMXRT1040-EVK board ships with the wireless module in the M.2 connector,
and with jumper J80 shorted. This causes a conflict with the USER_LED D8,
and the LED will not turn off. Samples and applications using USER_LED D8,
like blinky, require removal of J80 jumper.
Boot Header
-----------
If the debug probe fails to connect with the following error, it's possible
that the boot header in QSPI is invalid or corrupted. The boot header is
configured by :kconfig:option:`CONFIG_NXP_IMXRT_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 with the following
steps:
#. Set the SW4 DIP switches to OFF-OFF-OFF-ON to boot into the ROM bootloader.
#. Reset by pressing SW1
#. Run ``west debug`` or ``west flash`` again with a known working Zephyr
application.
#. Set the SW4 DIP switches to OFF-OFF-ON-OFF to boot from QSPI.
#. Reset by pressing SW1
Bluetooth Module
----------------
For Murate 2EL M.2 Mdoule, the following hardware rework needs to be applied,
Solder 0 ohm resistors for R96, and R93.
Remove resistors from R497, R498, R456 and R457.
And due to pin conflict issue, the PCM interface of Bluetooth module cannot be supported.
For the debugger fails to connect with the following error, please refer to section `WiFi Module`.
WiFi Module
-----------
If the debugger fails to connect with the following error, it's possible
the M.2 WiFi module is interfering with the debug signals
.. 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.
To resolve this, you may remove the M.2 WiFi module from the board when
flashing or debugging it, or remove jumper J80.
