NXP FRDM-KE17Z512

Overview

The FRDM-KE17Z512 is a development board for NXP Kinetis KE1xZ 32-bit MCU-based platforms. The onboard OpenSDAv2 serial and debug adapter, running an open source bootloader, offers options for serial communication, flash programming, and run-control debugging.

Other hardware features are not currently supported by the port.

System Clock

The KE17Z9 SoC is configured to run at 48 MHz using the FIRC.

Serial Port

The KE17Z9 SoC has three LPUARTs. UART2 is configured for the console.

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 Linkserver.

Early versions of this board have an outdated version of the OpenSDA bootloader and require an update. Please see the DAPLink Bootloader Update page for instructions to update from the CMSIS-DAP bootloader to the DAPLink bootloader.

Option 1: Linkserver

Install the LinkServer Debug Host Tools and make sure they are in your search path. LinkServer works with the default CMSIS-DAP firmware included in the on-board debugger.

Linkserver is the default for this board, west flash and west debug will call the linkserver runner.

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.

Connect a USB cable from your PC to J10.

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 frdm_ke17z512 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 build v3.6.0-xxxx-gxxxxxxxxxxxx ***
Hello World! frdm_ke17z512/mke17z9

Debugging

Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b frdm_ke17z512 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 build v3.6.0-xxxx-gxxxxxxxxxxxx ***
Hello World! frdm_ke17z512/mke17z9
