|
.. 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 the next section. |
|
|
|
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. |
