| on PTC16-17. |
| |
| System Clock |
| ============ |
| |
| The K64F SoC is configured to use the 50 MHz external oscillator on the board |
| with the on-chip PLL to generate a 120 MHz system clock. |
| |
| Serial Port |
| =========== |
| |
| The K64F SoC has six UARTs. One is configured for the console, another for BT |
| HCI, and the remaining are not used. |
| |
| USB |
| === |
| |
| The K64F SoC has a USB OTG (USBOTG) controller that supports both |
| device and host functions through its micro USB connector (K64F USB). |
| Only USB device function is supported in Zephyr at the moment. |
| |
| Programming and Debugging |
| ************************* |
| |
| The FRDM-K64F includes the :ref:`nxp_opensda` serial and debug adapter built |
| into the board to provide debugging, flash programming, and serial |
| communication over USB. |
| |
| To use the pyOCD tools with OpenSDA, follow the instructions in the |
| :ref:`nxp_opensda_pyocd` page using the `DAPLink FRDM-K64F Firmware`_. The |
| pyOCD tools are the default for this board, therefore it is not necessary to |
| set ``OPENSDA_FW=daplink`` explicitly when using the default flash and debug |
| mechanisms. |
| |
| With these mechanisms, applications for the ``frdm_k64f`` board |
| configuration can be built and flashed in the usual way (see |
| :ref:`build_an_application` and :ref:`application_run` for more |
| details). |
| |
| To use the Segger J-Link tools with OpenSDA, follow the instructions in the |
| :ref:`nxp_opensda_jlink` page using the `Segger J-Link OpenSDA V2.1 Firmware`_. |
| The Segger J-Link tools are not the default for this board, therefore it is |
| necessary to set ``OPENSDA_FW=jlink`` explicitly in the environment before |
| programming and debugging. |
| |
| Flashing |
| ======== |
| |
| This example uses the :ref:`hello_world` sample with the |
| :ref:`nxp_opensda_pyocd` tools. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: frdm_k64f |
| :goals: flash |
| |
| Open a serial terminal (minicom, putty, etc.) with the following settings: |
| |
| - Speed: 115200 |
| - Data: 8 bits |
| - Parity: None |
| - Stop bits: 1 |
| |
| Reset the board and you should be able to see on the corresponding Serial Port |
| the following message: |
| |
| .. code-block:: console |
| |
| Hello World! arm |
| |
| Debugging |
| ========= |
| |
| You can debug an application in the usual way. Here is an example for the |
| :ref:`hello_world` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: frdm_k64f |
| :maybe-skip-config: |
| :goals: debug |
