System Clock

The EFR32MG13P SoC is configured to use the 38.4 MHz external oscillator on the board.

Serial Port

The EFR32MG13P SoC has three USARTs and one Low Energy UARTs (LEUART with 9600 maximum baudrate). USART0 is used for the console.

Programming and Debugging

The tyzs3 board supports the runners and associated west commands listed below.

Flashing

This board supports jlink, openocd and pyocd. For pyocd, you have to install the pack first:

pyocd pack install efr32mg13p732f512gm48

Solder wires to the pins SWDIO, SWDCLK, nRST, GND and VCC (3.3V). Then connect them to a power source and a debug adapter of your choice.

Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b tyzs3 samples/hello_world
west flash

Open a serial terminal (minicom, putty, etc.) with the following settings:

Speed: 9600
Data: 8 bits
Parity: None
Stop bits: 1

Reset the board and you should see the following message in the terminal:

Hello World! tyzs3/efr32mg13p732f512gm48
