RP2040 Servo stops responding after firmata server side script killed and restart

[ale-novo]

Hello, i have a Client RP2040 board with the ConfigurableFirmata v3.0 library installed on it, and an Python script using Perl-Firmata server side firmata library running on a PC via USB. They both connect and communicate fine.

Ive noticed that with the RP2040 board, if i kill the script (control+c) and the re launch it, the board will re connect and communicate correctly, responds correctly to capability query, etc, but the servo no longer moves, until i recycle the power on the RP2040 board.

This does not happen with for example nano and esp8266, servo responds fine after i kill the script and re launch also this does not happen for example with I/O, stepper, encoder, analog, etc.

For some reason only RP2040 for servo is not responding after i kill the script.

i am running the firmata close method however to be completely frank im not sure if this is being executed after control+c as this is running in a subprocess for each connected board and im doing control+c from the main thread (terminal)

  except KeyboardInterrupt:
    logger.info("Stopping board %s", name)

    # write config when killed
    #save_config(True, accelstepper_list, stepper_list, encoder_list, button_list, led_list, switch_list, pot_list, config, config_file, timed)

    # move to init position when killed (does not work)
    #for s in stepper_list:
    #  s.start_pos()
    #for s in accelstepper_list:
    #  s.start_pos()
    logger.info("Disconnecting X-Plane")
    try:
      xp.xp_disconnect()
    except:
      pass

    logger.info("Closing firmata connection")
    firmata.close()
    logger.info("Exit")
    exit(1)

could the problem be failing to execute firmata close ? or just a bug with RP2040 as this does not happen in other boards? thanks
