SiWx917 Wi-Fi 6 and Bluetooth LE SoC 8 MB Flash Radio Board (SLWRB4338A)
Overview
The SiWx917-RB4338A (aka BRD4338A) radio board provides support for the Silicon Labs SiWG917 SoC. This board cannot be used stand-alone and requires a a Wireless Pro Kit Mainboard (Si-MB4002A aka BRD4002A), for power, debug options etc.
This board might be sold as a part of the SiWx917-PK6031A bundle (“SiWx917 Wi-Fi 6 and Bluetooth LE 8 MB Flash Pro Kit”), which includes the BRD4002A Mainboard in addition of the BRD4338A.
SiWG917 is an ultra-low power SoC that includes hardware support for Single-Band Wi-Fi 6 + Bluetooth LE 5.4, Matter…

Programming and Debugging
Flashing
Applications for the siwx917_rb4338a
board can be built in the usual
way. The flash method requires on Simplicity Commander installed on the host.
Then, connect the BRD4002A board with a mounted BRD4338A radio module to your host computer using the USB port.
Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b siwx917_rb4338a samples/hello_world
west 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 should see the following message in the terminal:
Hello World! siwx917_rb4338a
Debugging
Debuggning relies on JLink tool. JLink is not able to flash the firmware. So
debug session has to be done in two steps. west flash
will flahs the
firmware using Simplicity Commander. Then west attach
will use JLink to
attach to the board. The Zephyr image may has already booted when user runs
west attach
. User may execute monitor reset
in the gdb prompt to reset
the board.
