## renesas-rx72n
This example for `Renesas RX72N` demonstrates simple secure firmware update by wolfBoot. A sample application v1 is
securely updated to v2. Both versions behave the same except displaying its version of v1 or v2.
They are compiled by e2Studio and running on the target board.
In this demo, you may download two versions of application binary file by Renesas Flash Programmer.
You can download and excute wolfBoot by e2Studio debugger. Use a USB connection between PC and the
board for the debugger and flash programmer.
