+@par Example Description 
+
+This example demonstrates the dual Flash boot capability of XL-Density devices:
+boot from Flash memory Bank1 or Bank2.
+
+At startup, if BFB2 option bit is reset and the boot pins are in the boot from main
+Flash memory configuration, the device boots from Flash memory Bank1 or Bank2,
+depending on the activation of the bank. The active banks are checked in the following
+order: Bank2, followed by Bank1.
+The active bank is identified by the value programmed at the base address of the 
+bank (corresponding to the initial stack pointer value in the interrupt vector table). 
+For further details, please refer to AN2606 "STM32 microcontroller system memory boot mode."
+
+To demonstrate this feature, this example provides two programs:
+  - 1st program will be loaded in Flash Bank1 (starting from @ 0x08000000), for this
+     you have to enable BOOT_FROM_BANK1 define in main.c 
+  - 2nd program will be loaded in Flash Bank2 (starting from @ 0x08080000), for this
+     you have to enable BOOT_FROM_BANK2 define in main.c 
+
+Once these two programs are loaded and boot pins set in boot from Flash memory,
+after reset the device will boot from Bank1 (default). Then you have to follow
+the instructions provided on the LCD:
+  - "Joystick-DOWN: reset BFB2 bit to Boot from Bank2" => when pushing the Joystick
+     DOWN button, BFB2 option bit will be reset then a system (SW) reset will be
+     generated. After startup from reset, the device will boot from Bank2. 
+      - Note: when booting from Bank2 the same menu will be displayed
+ 
+  - "Joystick-UP: set BFB2 bit to Boot from Bank1" => when pushing the Joystick
+     UP button, BFB2 option bit will be set then a system (SW) reset will be
+     generated. After startup from reset, the device will boot from Bank1.       
+ 
+  - "Joystick-SEL: program to 0x0 the base @ of Bank1/2" => when pushing the Joystick
+     SEL button, the content of address 0x08080000 and 0x08000000 will be programmed to 0x0.
+       - If the program was previously booting from Bank2 (i.e. BFB2 bit is reset), 
+         in this case after reset no program is executed and the Bootloader code
+         is executed instead. 
+       - If the program was previously booting from Bank1 (i.e. BFB2 bit is set), 
+         in this case after reset no program is executed.
+       - You have to load again the two programs to Bank1 and Bank2.
+ 
+@b Important Note
+=================
+When BFB2 bit is cleared and Bank2 or/and Bank1 contain valid user application code,
+the Bootloader will always jump to this code and never continue normal code execution 
+(i.e. it’s no more possible to use the Bootloader for code upgrade and option bytes
+programming). As consequence, if the user has cleared BFB2 bit (to boot from Bank2),
+in order to be able to execute the embedded Bootloader code he has to: 
+   - either, set BFB2 bit to 1
+   - or, program the content of address 0x08080000 and 0x08000000 to 0x0
+=> This example allows performing the two actions described above.

+
+  - This example runs only on STM32F10x XL-Density Devices.
+  
+  - This example has been tested with STMicroelectronics STM3210E-EVAL (XL-Density) 
+    evaluation board and can be easily tailored to any development board.
