To digitally sign firmware images, you need a code-signing certificate and private key. For testing purposes, you can create a self‐signed certificate and private key. For production environments, purchase a certificate through a well‐known certificate authority (CA).
Different platforms require different types of code-signing certificates. The following sections describe how to create code-signing certificates for different FreeRTOS-qualified platforms.
