6.2 Usage Overview

This and the following subsections describe how to use and configure the applications. The process is illustrated in the following figure.

Figure 6-1. Overview of the Project Flow

The main steps are:

  • Create an application for the target AVR. If required, create an EEPROM layout in a separate file.
  • Create a configuration file with project dependent information. The application called GenTemp can be used for creating a file frame.
  • Run the application called Create. This will create the header file, key file, and the encrypted file.
  • Use Atmel Studio 7 or later, configure and build the bootloader for the target AVR
  • Download bootloader to target AVR and set lock and fuse bits
  • Now the encrypted firmware may be downloaded to the AVR at any time
