## Overview
|
|
The EFR32xG23 (xG23) Pro Kit is designed to support the development of Wireless
|
|
IoT devices based on Sub-GHz wireless protocols. The Pro Kit includes a radio
|
|
board that provides a complete reference design for the EFR32xG23 Wireless SoC,
|
|
with the matching network for +20 dBm covering 868 to 915 MHz.
|
|
|
|
The main board contains an onboard J-Link debugger with a Packet Trace
|
|
Interface and a Virtual COM port, enabling application development and
|
|
debugging of the attached radio board as well as external hardware through an
|
|
expansion header.

## Flashing the device
|
|
To flash, [SEGGER JLink](https://www.segger.com/jlink-software.html) is
|
|
required.
|
|
|
|
Flashing is supported by RIOT-OS using the command below:
|
|
|
|
```
|
|
make flash
|
|
```
|
|
|
|
To run the GDB debugger, use the command:
|
|
|
|
```
|
|
make debug
|
|
```
|
|
|
|
Or, to connect with your own debugger:
|
|
|
|
```
|
|
make debug-server
|
|
```
