Using CPC SPI on Linux Border Router#
This document refers to a setup build using:
BRD4271A as the Silicon Labs Radio Board
BRD8016A as the Silicon Labs Raspberry Pi Adapter Board
A Raspberry Pi as the host
Note: Pin mapping will need to be adapted to any custom hardware.
RCP SPI Connections#
SPI signals need to be allocated to pins connected to the host via the Radio Board connectors and the BRD8016A Raspberry Pi connector shown below.

RCP Project#
CPC Addition to Wi-SUN RCP Project#
Add Wi-SUN / Application / Wi-SUN RCP / Wi-SUN Border Router RCP - CPC Interface.
By default, this component uses UART. Follow the steps below to add CPC to your Wi-SUN project.
Install the Services / Co-Processor Communication / Secondary Device / Driver / CPC Secondary - SPI: Recommended SPI interface.
This creates the default
expCPC instance under Services / Co-Processor Communication / Secondary Device / Driver / CPC Secondary - SPI (EUSART) / exp.
Click Configure to check the SPI pin configuration, making sure it matches the RCP SPI connections for BRD4271A/BRD8016A/RPi hardware.
Press the Pin Tool button and filter on 'SPI' to get a pin view of SPI signals.
Build your CPC project.
Flash it on the RCP, clearing the flash before flashing (to get rid of any remaining NVM data).
Insert the RCP Radio Board on the BRD8016A Adapter Board.
Make sure that the expansion board switch is set to the High Power (LDO) mode.
Insert the BRD8016A on the Raspberry Pi header.
Border Router#
Note: As from 23Q4/GSDK V4.3.2, the CPC component in the GSDK will use the CPC Protocol v5, so the
cpcdinstallation on the Border Router also needs to use this version.
First of all CPC needs to be able to communicate with the RCP, independently from wsbrd.
To achieve this, cpcd needs to be compiled with the CPC Protocol v5, as follows:
Removing previous cpcd / libcpc Installs#

In /boot/config.txt, comment the UART line and add the SPI overlay as follows:

## Disable WiFi and Bluetooth, both potentially using UART
dtoverlay=disable-bt
dtoverlay=disable-wifi
# Disable UART
#enable_uart=1
# Enable SPI for CPC host/RCP communication
