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. * * \section SSec_Options Project Options * * The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value. * * <table> * <tr> * <td><b>Define Name:</b></td> * <td><b>Location:</b></td> * <td><b>Description:</b></td> * </tr> * <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> * </tr> * </table> */
