Connections and IOs
|
|
===================
|
|
|
|
The EFM32GG12 MCU has six GPIO controllers (PORTA to PORTF), all of which are
|
|
currently enabled for the SLTB009A board.
|
|
|
|
In the following table, the column **Name** contains pin names. For example, PE1
|
|
means pin number 1 on PORTE, as used in the board's datasheets and manuals.

System Clock
|
|
============
|
|
|
|
The EFM32GG12 MCU is configured to work at 72 MHz.
|
|
|
|
Serial Port
|
|
===========
|
|
|
|
The EFM32GG12 SoC has five USARTs, two UARTs and two Low Energy UARTs (LEUART).
|
|
USART0 is connected to the board controller and is used for the console.

|
|
Programming and Debugging
|
|
*************************
|
|
|
|
.. note::
|
|
Before using the kit the first time, you should update the J-Link firmware
|
|
from `J-Link-Downloads`_
|
|
|
|
Flashing
|
|
========
|
|
|
|
The SLTB009A includes an `J-Link`_ serial and debug adaptor built into the
|
|
board. The adaptor provides:
|
|
|
|
- A USB connection to the host computer
|
|
- A physical UART connection which is relayed over interface USB serial port.
|
|
|
|
Flashing an application to SLTB009A
|
|
--------------------------------------
|
|
|
|
Connect the SLTB009A to your host computer using the USB port.
|
|
|
|
Here is an example to build and flash the :ref:`hello_world` application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: efm32gg_stb009a
|
|
:goals: flash
|
|
|
|
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:
|
|
|
|
.. code-block:: console
