Got my first AVRprocessors by snailmail last friday, still struggling
to make avrdude make butterfly talk over ATmega169 / UART-port.
I haven't figured out how it is accessed thru Avrdude.
I assume communication should be performed via the Bootloader?
The USB-serial link is working (can fill the NAME-space)but not under
avrdude.
I tried this: ---> G4-MiniMac:/usr/local/bin rh$ avrdude -p
ATmega169 -c butterfly -P /dev/tty.usbserial -t -v <---
from the terminal vindow without success so I started to analyze the
RS-232 coommunication with a Serial Tool.
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?
I might be wrong...
ATMELs documentation is either not found or not detiled enough and I
haven't invested in their hardware except Butterfly and some
porcessors....
So some advice would be very appreciated!
