Both are /not/ the same protocols. Please use AVR109 rather than AVR910. Not only that AVR109 is guaranteed to have a block transfer mode, but it no longer suffers from the idiotic device code saga: the device code is just moot there (and could even be left out), because the signature byte is to be used for device identification instead. > What I'm looking for is a "debug" mode for AVRDUDE, ... -vvvv (four -v options). Note that all debugging IO goes to stderr (rather than stdout), so you have to capture file descriptor 2 in order to record the debugging output into a file. This works like avrdude ... 2> debug.log Works both under a (Bourne-style) Unix shell, as well as under WinNT's cmd.exe.
