+ * + * \section SSec_Description Project Description: + * + * This bootloader enumerates to the host as a HID Class device, allowing for device FLASH programming through + * the supplied command line software, which is a modified version of Paul's TeensyHID Command Line loader code + * from PJRC (used with permission). This bootloader is deliberately non-compatible with the proprietary PJRC + * HalfKay bootloader GUI; only the command line interface software accompanying this bootloader will work with it. + * + * Out of the box this bootloader builds for the AT90USB1287 with an 8KB bootloader section size, and will fit + * into 2KB of bootloader space for the Series 2 USB AVRs (ATMEGAxxU2, AT90USBxx2) or 4KB of bootloader space for + * all other models. If you wish to alter this size and/or change the AVR model, you will need to edit the MCU, + * FLASH_SIZE_KB and BOOT_SECTION_SIZE_KB values in the accompanying makefile. + * + * \warning THIS BOOTLOADER IS NOT SECURE. Malicious entities can recover written data, even if the device + * lockbits are set. + * + * \section Sec_Running Running the Bootloader + * + * This bootloader is designed to be started via the \c HWB mechanism of the USB AVRs; ground the \c HWB pin (see device + * datasheet) then momentarily ground \c /RESET to start the bootloader. This assumes the \c HWBE fuse is set and the + * \c BOOTRST fuse is cleared. + * + * \section Sec_Installation Driver Installation + * + * This bootloader uses the HID class driver inbuilt into all modern operating systems, thus no additional drivers + * need to be supplied for correct operation. + * + * \section Sec_HostApp Host Controller Application + * + * Due to licensing issues, the supplied bootloader is compatible with the HalfKay bootloader protocol designed + * by PJRC, but is not compatible with the cross-platform loader GUI. A modified version of the open source + * cross-platform TeensyLoader application is supplied, which can be compiled under most operating systems. The + * command-line loader application should remain compatible with genuine Teensy boards in addition to boards using + * this custom bootloader. + * + * Once compiled, programs can be loaded into the AVR's FLASH memory through the following example command: + * \code + * hid_bootloader_cli -mmcu=at90usb1287 Mouse.hex + * \endcode + * + * \section Sec_KnownIssues Known Issues: + * + * \par After loading an application, it is not run automatically on startup. + * Some USB AVR boards ship with the \c BOOTRST fuse set, causing the bootloader + * to run automatically when the device is reset. This booloader requires the + * \c BOOTRST be disabled and the HWBE fuse used instead to run the bootloader + * when needed. + * + * \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. + * + * + * + * + * + *
