      Hi,

      since the latest update (unipi-kernel-modules-dkms 1.36) I am having issues with my Neuron M103.

      Starting the tcp-server manually results in an error about /dev/unipispi:

      root@zentrale:/heizung/src# /opt/unipi/tools/unipi_tcp_server -p 502 -l 0.0.0.0  --verbose --check-firmware
      ARMINIT: Cannot open device /dev/unipispi
      ARMINIT: Cannot open device /dev/unipispi
      ARMINIT: Cannot open device /dev/unipispi
      UniPi TCP Modbus Server: Listening Connection Established RET:3
      poll timeout = -1[ms]
      Starting primary loop
      

      When trying to access through modbus I get an error:
      fieldbus_get_ai error: Slave device or server failure

      So looks like I can not open unipispi device. Modules seems to be loaded:

      root@zentrale:/heizung/src# lsmod| grep unipi
      rtc_unipi              16384  0
      root@zentrale:/heizung/src# lsmod| grep spi
      spidev                 20480  0
      spi_bcm2835            20480  0
      

      Anyone having a clue how to deal with this issue?

      Thanks a lot!

        Hi,

        I fixed it by
        apt install neuron-kernel

        It uninstalled dmks modules- I am unsure if this is a proper solution. At least it seems to work now.

        Greetings
