      Hi,

      I noticed recently these messages in my syslog:

      Apr  9 08:53:33 zentrale kernel: [  200.867042] UNIPISPI: part1 b3:07:00:00
Apr  9 08:53:33 zentrale kernel: [  200.972499] UNIPISPI: SPI CRC2 Not Correct: 2108 COMPUTED: 23f8

Apr  9 08:53:33 zentrale kernel: [  200.977276] UNIPISPI: len=42, part1=fa:00:55:0e part2=01:01:04:c0:00:00:00:0c:00:00:00:11:e5:00:40:00
Apr  9 08:53:33 zentrale kernel: [  200.979490] UNIPISPI: SPI CRC1 Not Correct (Received: 0000 Calculated: 9b77)

      I understand there is some CRC32 mismatch possibly related to some SPI device.

      But what does it mean in detail and how can I prevent this message- or is something seriously broken?
      I haven't noticed anything not working- but I am not using SPI devices (afaik).

      Thanks in advance!

        Hi,

        meanwhile I found a "solution" based on this post.

        I did an

        apt-cache policy unipi-kernel-modules

        which revealed the available version names.
        Followed by

        apt install unipi-kernel-modules=1.106.1.20220308~buster-1

        it installed the previous version and all is smooth again.

        Still, this is a workaround but not a solution.

          Hi,

          i'm experiencing the exact same problem on a freshly flashed SD card with neuron-node-red_image-20220406.0.zip

          @knebb your tip fixes this, so thanks for that.

          i guess it probably needs a more structural fix, so hopefully this will be included in the next available flash image...

          thanks anyway for posting this... it fortunately solves my problems without a lot of haystacking

          Cheers, Tony

            Same problem still present on neuron-node-red_image-20220412.0, see here for details
            Thanks to you @knebb I am now able to use my system again. Let's hope they fix this soon.

              I just upgraded to unipi-kernel-modules 1.112.1.20220308~buster-1 and it looks like they fixed the error.

                Hi everybody,

                It has been fixed with a new version of the unipi-kernel-modules package.
                At the same time, we increased the output testing of packages.

                Best regards,
                Antonin
