* * \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. * * As an open-source option, this bootloader is also compatible with the Linux Atmel USB DFU Programmer * software, available for download at http://sourceforge.net/projects/dfu-programmer/. * * 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. * * NOTE: 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. * * * * * * * * * * * * *
Define Name:Location:Description:
SECURE_MODEBootloaderDFU.hIf 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.
