      Hi,
      All the DI/DO's on my M207 have stopped working. I cannot connect to them anymore using the Evok or modbus API. The problem seems to have occurred after updating from evok/bookworm 3.0.5.1~bookworm to evok/bookworm 3.0.6.1~bookworm, but downgrading evok doesn't solve the problem.

      The kernel log shows that the device isn't able to connect to spi2.0 en spi2.1:

      Any ideas what is the problem? Thanks in advance!

        Hello,
        do the run LEDs blink or not?

          Hello Krystof,
          yes, run1 and run2 are blinking (1 sec on, 1 sec off and so on).

            @bertf Then it seems like a software issue, I would recommend you switching to the latest OS.

              Sorry for my very late respons. As suggested I did a complete reinstall of the most recent Unipi Patron OS - Debian 12, but also a reinstall of the earlier Debian 10. I tried several times but both OS-versions didn't reconnect the device to the DI/DO/RO's. Same message in the kernel log each time: "spi channel looks empty". Can it be a hardware problem?

                Hello @bertf,
                this looks like a hardware problem, do you remember which firmware version did you have before?

                Best regards,

                  Hi @cleve
                  I'm not sure. I use the images from the Unipi-website and the standard repo's that come with them. I have local backups from 'patron-base-os_12.20240701.0' and 'patron-node-red_12.20240701.0'. I will have used one of these images to initially migrate from Debian 10 to 12. The reinstall as mentioned above is done with image 'patron-node-red_12.20240917.1'.
                  Kind regards,
                  Bert
