Flashing

The xG27 Dev Kit includes an embedded J-Link adapter built around EFM32GG12 microcontroller (not user-programmable). The adapter provides:

• SWD interface to EFR32BG27 for flashing and debugging.

• SWO trace interface to EFR32BG27 for tracing.

• UART interface to EFR32BG27 for console access.

• A USB connection to the host computer, which exposes CDC-ACM Serial Port endpoints for access to the console UART interface and proprietary J-Link endpoints for access to the SWD and SWO interfaces.

UART functionality of the adapter is accessible via standard CDC-ACM USB driver present in most desktop operating systems and any standard serial port terminal program e.g. picocom.

SWD and SWO functionality is accessible via Simplicity Commander.

The simplest way to flash the board is by using West, which runs Simplicity Commander in unattended mode and passes all the necessary arguments to it.

• If Simplicity Commander is installed in the system and the directory in which commander executable is located is present in the PATH environment variable:

  west flash
  

• Otherwise, one should specify full path to the commander executable:

  west flash --commander <path_to_commander_directory>/commander
  

• In case several J-Link adapters are connected, you must specify serial number of the adapter which should be used for flashing:

  west flash --dev-id <J-Link serial number>
  

Programming and Debugging

The sample application Hello World is used for this example. Build the Zephyr kernel and application:

# From the root of the zephyr repository
west build -b xg27_dk2602a samples/hello_world

Connect your device to your host computer using the USB port and you should see a USB connection. Use west’s flash command

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:

Hello World! xg27_dk2602a
