* \section SSec_Description Project Description:
|
|
*
|
|
* This bootloader enumerates to the host as a DFU Class device, allowing for DFU-compatible programming
|
|
* software to load firmware onto the AVR.
|
|
*
|
|
* This bootloader is compatible with Atmel's FLIP application. However, it requires the use of Atmel's
|
|
* DFU drivers. You will need to install Atmel's DFU drivers prior to using this bootloader. If you are
|
|
* using a 64 bit Windows OS, you will need to either disable the driver signing requirement (see online
|
|
* tutorials for details) or use a digitally signed version of the official Atmel driver provided by a
|
|
* third party AVR user at
|
|
* <a>http://www.avrfreaks.net/index.php?module=Freaks%20Academy&func=viewItem&item_id=2196&item_type=project</a>.
|
|
*
|
|
* As an open-source option, this bootloader is also compatible with the Linux Atmel USB DFU Programmer
|
|
* software, available for download at <a>http://sourceforge.net/projects/dfu-programmer/</a>.
|
|
*
|
|
* If SECURE_MODE is defined as true, upon start-up the bootloader will be locked, with only the chip erase
|
|
* function available (similar to Atmel's DFU bootloader). If SECURE_MODE is defined as false, all functions
|
|
* are usable on start-up without the prerequisite firmware erase.
|
|
*
|
|
* Out of the box this bootloader builds for the USB1287, and should fit into 4KB of bootloader space. If
|
|
* you wish to enlarge this space and/or change the AVR model, you will need to edit the BOOT_START and MCU
|
|
* values in the accompanying makefile.
|
|
*
|
|
* <b>NOTE:</b> This device spoofs Atmel's DFU Bootloader USB VID and PID so that the Atmel DFU bootloader
|
|
* drivers included with FLIP will work. If you do not wish to use Atmel's ID codes, please
|
|
* manually change them in Descriptors.c and alter your driver's INF file accordingly.

|
|
* The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.

|
|
* <tr>
|
|
* <td>SECURE_MODE</td>
|
|
* <td>BootloaderDFU.h</td>
|
|
* <td>If defined to true, the bootloader will not accept any memory commands other than a chip erase on start-up, until an
|
|
* erase has been performed. This can be used in conjunction with the AVR's lockbits to prevent the AVRs firmware from
|
|
* being dumped by unauthorized persons.</td>
