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> */Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
