## 1. Overview
This example demonstrates simple secure firmware boot from extarnal flash by wolfBoot.
A sample application v1 is securely loaded into internal RAM if there is not higher version in update region. A sample application v2 will be loaded when it is in update region.Both versions behave the same except blinking LED Red(v1) or Yello(v2). They are compiled by e2Studio and running on the target board.

In this demo, you may download two versions of the application binary file.
You can download and execute wolfBoot by e2Studio debugger. Use a USB connection between PC and the board for the debugger and flash programmer.
