Overview

Silicon Labs provides pre-built NCP images and sample NCP applications for different use cases in the stack. The customer has the option to either use one of the pre-built NCP images or use sample NCP applications or a blank NCP application to build customized NCP applications.

Prerequisite resources

The below resources provide good information before continuing with generating Smart Energy customized NCP images.

The AN1010 application note provides a detailed guide about building a customized NCP application.
You can find this here:

Another useful application note is AN714, this guide provides information about the smart energy ECC-enabled device setup process.
You can find this here:

The KBA at the link below provides information about the ECC libraries and adding them to the stack.

Building the custom project

Customers cannot generate the exact copy of the pre-build images but, if they use one of the NCP sample applications and make the changes listed below then they can generate an NCP image functionally similar to the pre-built NCP images.
The steps to generate smart energy NCP image similar to pre-built smart energy NCP image:

Step1:

Start a new customized NCP project based on one of the sample NCP applications. You may select the 'xncp-commshub-uart-dual' sample NCP application for CommsHub and the 'ncp-uart-hw' sample for end devices depending on your needs.
 

Step2:

Select the following plugins and do not change any other already selected plugins.
    

•   XNCP Stub Library
•   Zigbee PRO Stack Library
•   Zigbee Light Link Stub Library
•   Zigbee PRO Core Security Library
•   Security Link Keys Library
•   End Device Bind Library
•   Binding Table Library
•   ECC 163k1 Library
•   ECC 283k1 Library
•   CBKE Core Library
•   CBKE 163k Library
•   CBKE 283k Library
•   Install Code Library
•   CBKE DSA Verify Library
•   CBKE DSA Sign Stub Library
•   CBKE 283k DSA Verify Library
•   Packet Validate Library
•   Multi-Network Stub Library
•   GreenPower Stack Stub Library
•   Concentrator Support Library 
  • NOTE: The Concentrator Support Library plugin has been moved to the HOST side after EmberZNet 6.7.0
•   Manufacturing Library

For CommsHub/Coordinator devices make sure to include: 

• Source Route Stack Library

Step3:

Select Zigbee PRO Stack Library plugin and set Child Table Size to 32. The other settings selected by the sample NCP application are ok.

Step4:

Generate and build the project.
