| Overview |
| ******** |
| |
| The i.MX RT1050 is a new processor family featuring NXP's advanced |
| implementation of the ARM Cortex-M7 Core. It provides high CPU performance and |
| real-time response. |
| |
| The i.MX RT1050 provides various memory interfaces, including SDRAM, Raw NAND |
| FLASH, NOR FLASH, SD/eMMC, Quad SPI, HyperBus and a wide range of other |
| interfaces for connecting peripherals, such as WLAN, Bluetooth™, GPS, displays, |
| and camera sensors. As with other i.MX processors, i.MX RT1050 also has rich |
| audio and video features, including LCD display, basic 2D graphics, camera |
| interface, SPDIF, and I2S audio interface. |
| |
| The following document refers to the discontinued MIMXRT1050-EVK board. For the |

| .. note:: |
| In order to use the SPI peripheral on this board, resistors R278, |
| R279, R280, and R281 must be populated with zero ohm resistors |
| |
| System Clock |
| ============ |
| |
| The MIMXRT1050 SoC is configured to use the 32 KHz low frequency oscillator on |
| the board as a source for the GPT timer to generate a system 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. |
| |
| USB |
| === |
| |
| The RT1050 SoC has two USB OTG (USBOTG) controllers that supports both |
| device and host functions through its micro USB connectors. |
| Only USB device function is supported in Zephyr at the moment. |
| |
| 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. |
| |
| Follow the instructions in `Enable QSPI flash support in SEGGER JLink`_ |
| in order to support your EVK if you have modified it to boot from QSPI NOR |
| flash as specified by NXP AN12108. |
| |
| 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 |
| |
| Troubleshooting |
| =============== |
| |
| If the debug probe fails to connect with the following error, it's possible |
| that the boot header in HyperFlash is invalid or corrupted. The boot header is |
| configured by :kconfig:option:`CONFIG_NXP_IMX_RT_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 HyperFlash with the following |
| steps: |
| |
| #. Set the SW7 DIP switches to ON-ON-ON-OFF to prevent booting from HyperFlash. |
| |
| #. Reset by pressing SW4 |
| |
| #. Run ``west debug`` or ``west flash`` again with a known working Zephyr |
| application. |
| |
| #. Set the SW7 DIP switches to OFF-ON-ON-OFF to boot from HyperFlash. |
| |
| #. Reset by pressing SW4 |
| |
| 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 |
