PA8	GPIO	LED0
PA5	USART0_TX	UART Console EFM_BC_TX US0_TX
PA6	USART0_RX	UART Console EFM_BC_RX US0_RX

The default configuration can be found in boards/sparkfun/thing_plus_matter_mgm240p/sparkfun_thing_plus_matter_mgm240p_defconfig

System Clock

The EFR32MG24 SoC is configured to use the 39 MHz external oscillator on the board.

Serial Port

The EFR32MG24 SoC has one USART and two EUSARTs. USART0 is connected to the board controller and is used for the console.

Programming and Debugging

The sparkfun_thing_plus_matter_mgm240p board supports the runners and associated west commands listed below.

	flash	debug	rtt	attach	debugserver
jlink	✅ (default)	✅ (default)	✅	✅	✅

Note

Before using the kit the first time, you should update the J-Link firmware in Simplicity Studio.

Flashing

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 sparkfun_thing_plus_mgm240p samples/hello_world

Connect the sparkfun_thing_plus_mgm240p to your host computer using the USB port and you should see a USB connection.

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’ll see the following message on the corresponding serial port terminal session:

Hello World! _sparkfun_thing_plus_matter_mgm240p

Bluetooth

To use the BLE function, run the command below to retrieve necessary binary blobs from the SiLabs HAL repository.

west blobs fetch silabs

Then build the Zephyr kernel and a Bluetooth sample with the following command. The Observer sample application is used in this example.

# From the root of the zephyr repository
west build -b sparkfun_thing_plus_matter_mgm240p samples/bluetooth/observer
