If someone could help me I would be very grateful.
When I connect the Arduino to the Arduino IDE I have to select the old bootloader in the Processor menu. If I don't select it, the same thing happens as with openroberta. The arduino flashes briefly but gets no code. My OS is Linux, my OR USB connection is version 3.1, but an acquaintance I communicate with, who has the same problem with the OR USB connection under windows, probably has a newer version, where there is already the extended menu.
Can I choose the bootloader or the processor type under OpenRoberta?
