No connection to ATmega4809

[StefMijs]

I try want to program an atmega4809 on a arduino nano every with an raspberry pi 4B with it's tx/rx pins.(The usb cable is no option) I wave used the the following command to find the device but there is no response. $ sudo pymcuprog ping -d atmega4809 -t uart -u /dev/serial1 Connecting to SerialUPDI When i quit the command with ^C after a long time of waiting for response i get the following message: ` ^CTraceback (most recent call last): File "/usr/local/bin/pymcuprog", line 8, in sys.exit(main()) File "/usr/local/lib/python3.9/dist-packages/pymcuprog/pymcuprog.py", line 292, in main return pymcuprog_main.pymcuprog(arguments) File "/usr/local/lib/python3.9/dist-packages/pymcuprog/pymcuprog_main.py", line 82, in pymcuprog status = _start_session(backend, device_selected, args) File "/usr/local/lib/python3.9/dist-packages/pymcuprog/pymcuprog_main.py", line 562, in _start_session backend.start_session(sessionconfig) File "/usr/local/lib/python3.9/dist-packages/pymcuprog/backend.py", line 376, in start_session self.programmer.setup_device( File "/usr/local/lib/python3.9/dist-packages/pymcuprog/programmer.py", line 82, in setup_device self.device_model = get_nvm_access_provider(self.transport, File "/usr/local/lib/python3.9/dist-packages/pymcuprog/nvm.py", line 44, in get_nvm_access_provider accessprovider = NvmAccessProviderSerial(transport, device_info, baud=frequency, options=options) File "/usr/local/lib/python3.9/dist-packages/pymcuprog/nvmserialupdi.py", line 51, in init self.avr = UpdiApplication(port, baud, self.dut) File "/usr/local/lib/python3.9/dist-packages/pymcuprog/serialupdi/application.py", line 72, in init self.phy = UpdiPhysical(serialport, baud) File "/usr/local/lib/python3.9/dist-packages/pymcuprog/serialupdi/physical.py", line 31, in init self.send([constants.UPDI_BREAK]) File "/usr/local/lib/python3.9/dist-packages/pymcuprog/serialupdi/physical.py", line 100, in send self.ser.write(command) File "/usr/lib/python3/dist-packages/serial/serialposix.py", line 622, in write abort, ready, _ = select.select([self.pipe_abort_write_r], [self.fd], [], None) KeyboardInterrupt

When i use serial0 i get this massage: pymcuprog.pymcuprog - ERROR - Operation failed with error: (22, 'Invalid argument') ` I have connected it like the the following image.

With kind regards.
