Add three more -v options, and you'll see a trace of the entire communication. > There is some lowlevel protocol found in an ATMEL pdf-file, AVR109 > and I assume that or part of it is running in the bootloader? Actually, the butterfly protocol is not identical but close to AVR109. AVR109 is the protocol of a standalone programmer that could program different (external) AVRs, while a bootloader can only program a single chip. -- cheers, J"org .-.-. --... ...-- -.. .
