The default configuration can be found in boards/nxp/rddrone_fmuk66/rddrone_fmuk66_defconfig

Other hardware features are not currently supported by the port.

System Clock

The K66F SoC is configured to use the 16 MHz external oscillator on the board with the on-chip PLL to generate a 160 MHz system clock.

Serial Port

The K66F SoC has six UARTs. LPUART0 is configured for the console, UART0 is labeled Serial 2, UART2 is labeled GPS, UART4 is labeled Serial 1. Any of these UARTs may be used as the console by overlaying the board device tree.

USB

The K66F SoC has a USB OTG (USBOTG) controller that supports both device and host functions through its micro USB connector (K66F USB). Only USB device function is supported in Zephyr at the moment.

Programming and Debugging

Build and flash applications as usual (see Building an Application and Run an Application 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 jlink. The board package with accessories comes with a jlink mini edu and cable specifically for this board along with a usb to uart that connects directly to the jlink mini edu. This is the expected default configuration for programming and getting a console.

# From the root of the zephyr repository
west build -b rddrone-fmuk66 samples/hello_world

Configuring a Console

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 Hello World application.

# From the root of the zephyr repository
west build -b rddrone-fmuk66 samples/hello_world
west flash

Open a serial terminal, reset the board (press the SW1 button), and you should see the following message in the terminal:

***** Booting Zephyr OS v2.7.0 *****
Hello World! rddrone-fmuk66

Debugging

Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b rddrone-fmuk66 samples/hello_world
west debug

Open a serial terminal, step through the application in your debugger, and you should see the following message in the terminal:

***** Booting Zephyr OS v2.7.0 *****
Hello World! rddrone-fmuk66
