The generic approach of calling avrdude to perform a reset with `make reset` does also work on board with a bootloader, but only if no other process is also accessing the serial (e.g. via `make term`). `make test` first accesses the serial and then performs `make reset` to not miss any output on the serial. This however blocks when `make reset` also wants to access that serial. As workaround, `make reset` is no only provided if the ATmega device is not programmed via bootloader. Normally, those boards reset anyway upon `make term`, which allows `make test` to work normally again.
