I know this question has been asked "“ and answered "“ before. But the answers are now obsolete. The wanted files are nowhere to be found in the AS6 file structure.
Does anyone know where the source code for the AVR32 DFU bootloader can be found? The best link I have found is here: http://support.atmel.no/knowledgebase/avr32studiohelp/AT32UC3B_Software_Framework/SERVICES/USB/CLASS/DFU/EXAMPLES/ISP/DOC/html/files.html
But the actual files cannot be downloaded as such. All I can do is copy the text from the one web page at a time, paste it into a text editor, and remove all the line numbers. Somehow, that doesn't seem right. (But I'll do it if there is no other way.)
I would like to use the files for inspiration, because I am about to write a bootloader for the AVR32. I've done this before for ATmega and xmega controllers, but the AVR32 is a bit more tricky.
