Normally, the + * reprogramming of an AVR device must be performed using a special piece of programming hardware, through one of the + * supported AVR programming protocols - ISP, HVSP, HVPP, JTAG or dW. This can be done through a custom programmer, + * a third party programmer, or an official Atmel AVR tool - for more information, see the Atmel.com website. + * + * Alternatively, you can use the bootloader. From the Atmel factory, each USB AVR comes preloaded with the Atmel + * DFU (Device Firmware Update) class bootloader, a small piece of AVR firmware which allows the remainder of the + * AVR to be programmed through a non-standard interface such as the serial USART port, SPI, or (in this case) USB. + * Bootloaders have the advantage of not requiring any special hardware for programming, and cannot usually be erased + * or broken without an external programming device. They have disadvantages however; they cannot change the fuses of + * the AVR (special configuration settings that control the operation of the chip itself) and a small portion of the + * AVR's FLASH program memory must be reserved to contain the bootloader firmware, and thus cannot be used by the + * loaded application. Atmel's DFU bootloader is either 4KB (for the smaller USB AVRs) or 8KB (for the larger USB AVRs). + * + * If you wish to use the DFU bootloader to program in your application, refer to your DFU programmer's documentation. + * Atmel provides a free utility called FLIP which is USB AVR compatible, and an open source (Linux compatible) + * alternative exists called "dfu-programmer". + */ -- cgit v1.2.3
