MIMXRT1050 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 MIMXRT1050 SoC has eight UARTs. ``LPUART1`` is configured for the console, ``LPUART3`` for the Bluetooth Host Controller Interface (BT HCI), 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. Option 1: :ref:`opensda-jlink-onboard-debug-probe` (Recommended) ---------------------------------------------------------------- Install the :ref:`jlink-debug-host-tools` and make sure they are in your search path. Follow the instructions in :ref:`opensda-jlink-onboard-debug-probe` to program the `OpenSDA J-Link MIMXRT1050-EVK-Hyperflash Firmware`_. Check that jumpers J32 and J33 are **on** (they are on by default when boards ship from the factory) to ensure SWD signals are connected to the OpenSDA microcontroller. Option 2: :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 20-pin connector to J21. Check that jumpers J32 and J33 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 J30 and J31 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 J28. 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: mimxrt1050_evk :goals: flash Open a serial terminal, reset the board (press the SW4 button), and you should see the following message in the terminal: .. code-block:: console ***** Booting Zephyr OS v1.14.0-rc1 ***** Hello World! mimxrt1050_evk Debugging ========= Here is an example for the :ref:`hello_world` application. .. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: mimxrt1050_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 v1.14.0-rc1 ***** Hello World! mimxrt1050_evk Board Revisions *************** The original MIMXRT1050-EVK (rev A0) board was updated with a newer MIMXRT1050-EVKB (rev A1) board, with these major hardware differences:: - SoC changed from MIMXRT1052DVL6**A** to MIMXRT1052DVL6**B** - Hardware bug fixes for: power, interfaces, and memory - Arduino headers included For more details, please see the following `NXP i.MXRT1050 A0 to A1 Migration Guide`_.
