See the Programming section on the info page, you will need the firmware and Atmel-compatible DFU (device firmware update) software on your computer to reflash the target. Might not be working and would need reprogramming.You would need to reflash the bootloader and proper fuses, again, see the appropriate info page for your device.Īrduino Mega 2560 only: ATmega8U/16U software Sometimes software that runs in a tight loop will prevent the bootloader from connecting.īarring that, the fuses might have gotten messed up or the code erased. Try to reset the AVR (press and release the button) while the programmer is attempting to connect. If the programmer is not resetting the micro before attempting to connect, this might be the reason. The AVR is not executing the bootloader for some reason. If you don't, something is wrong up-stream of the chip, it could be the communications chip (I think the Arduino 2560 uses a secondary AVR instead of an FTDI for some reason, so that could be broken, either its software or hardware)

It might be worth checking again though, sometimes USB COM devices install on strange port numbers.Ĭonnect TX to RX (and disconnect them from the AVR if possible) then open a terminal on the COM port, you should see characters echoed if you type them. What causes this can be numerous and varied, some possible issues:īlinking is happening, so hopefully you aren't using the wrong port. The error message basically means that the programmer is unable to contact the bootloader on the device the code you're trying to upload has no bearing on the problem.
