I'm having issues flashing an application over RS485. It looks like it finds the bootloader but never is able to read the type or software version. I'm not sure what I am doing wrong here.
Here is the output of avrdude:

Description : Atmel AppNote AVR109 Boot Loader
Connecting to programmer: .
Found programmer: Id = "XBoot++"; type = ?
Software Version = ?.?; No Hardware Version given.
avrdude: error: buffered memory access not supported. Maybe it isn't
a butterfly/AVR109 but a AVR910 device?
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.
avrdude: error: programmer did not respond to command: leave prog mode
avrdude: error: programmer did not respond to command: exit bootloader
avrdude done. Thank you.
