      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.
