&par Example Description

The example aims to show how to configure a bootloader firmware to IAP.
When device connect to HyperTerminal right, a usart menu will show to user.
The menu as follow:

***************************************************************

*                                              (Version 1.0.0)*

Flash ROM Space:
 - IAP_Bootloader       0x08000000 - 0x08005FFF
 - IAP_Application1     0x08006000 - 0x08007FFF
 - IAP_Application2     0x08008000 - 0x08009FFF

note:

Before using the IAP function, you must download the bootloader program to the target board.  
Then compile the "IAP_Application1" or "IAP_Application2" project, and update the generated bin  
firmware file to the target board using the IAP function through the HyperTerminal tool.  
The firmware file transfer is performed using the YMODEM protocol.
