2.2.1 Bootloader and Application Detection

The Application Manager detects if the bootloader or the application should be executed by applying the following rules:

  • Application is executed if
    • The bootloader is not forced by an external event or by application (see Section 2.2.1.1)
  • Bootloader is executed if
    • It is forced by an external event or by the application

      OR

    • The application is invalid

Figure 2-3 shows the implementation of this decision process.
