    • RE: "UNIPISPI: SPI CRC2 Not Correct" - why?

      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.

    • RE: unipi-kernel-modules-dkms 1.108 breaks the system on kernel 5.10.103-v7+

      @Achilleas-Kotsis

      Thanks for your hints about downgrading. Worked for me, too.

      For reference the commands here:

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

      I got the version by apt-cache policy unipi-kernel-modules.

    • RE: Upgrading to Bullseye?

      I did as shown above. Ended in an Neuron M103 not booting :(

      Unfortunately I do not have a possibility to attach a screen to M103 (or can I use the HDMI of the inner Raspi?)

      I ended up in restoring the previous image.

      So I can not even tell what the issue was- I guess some kernel/ grub based issues.

      At current stage I would recommend against the above upgrade procedure.

    • RE: Upgrading to Bullseye?

      Hi all,

      anyone having a hint how to upgrade now to Debian 11? I do not want to risk my installation here....

      For Debian/ Raspbian I will have to replace "buster" with "bullseye", right?
      /etc/apt/sources.list.d/raspi.list:

      deb http://archive.raspberrypi.org/debian/ buster main ui
      

      Additionally I need to do the same here, correct?
      /etc/apt/sources.list.d/unipi.list:

      deb https://repo.unipi.technology/debian buster main
      

      Once edited, run apt update; apt full-upgrade; apt autoremove based on this tutorial.

      Is this the way to go?

      Greetings

    • RE: SD Card problem

      @CKB
      Not sure it this might help you. But I have configured my OS to run "read-only". It helps for longer lasting SD cards and it will usually not corrupt upon power outage.

      If you are interested, you might search for "Raspbian Read only".
      See below my filesystems (just the main parts):

      tmpfs on /run type tmpfs (rw,nosuid,noexec,relatime,size=99612k,mode=755)
      /dev/mmcblk0p2 on / type ext4 (ro,noatime)
      tmpfs on /run/lock type tmpfs (rw,nosuid,nodev,noexec,relatime,size=5120k)
      tmpfs on /var/cache type tmpfs (rw,nosuid,nodev,relatime)
      tmpfs on /tmp type tmpfs (rw,nosuid,nodev,relatime)
      tmpfs on /var/tmp type tmpfs (rw,nosuid,nodev,relatime)
      tmpfs on /var/log type tmpfs (rw,nosuid,nodev,relatime)
      /dev/mmcblk0p1 on /boot type vfat (rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,errors=remount-ro)
      

      And this is /etc/fstab:

      PARTUUID=7965901e-01  /boot           vfat    ro,defaults          0       2
      PARTUUID=7965901e-02  /               ext4    ro,defaults,noatime  0       1
      # a swapfile is not a swap partition, no line here
      #   use  dphys-swapfile swap[on|off]  for that
      tmpfs /tmp       tmpfs nodev,nosuid 0 0
      tmpfs /var/log   tmpfs nodev,nosuid 0 0
      tmpfs /var/tmp   tmpfs nodev,nosuid 0 0
      tmpfs /var/cache tmpfs nodev,nosuid 0 0

    • RE: Upgrading to Bullseye?

      @Martin-Kudláček said in Upgrading to Bullseye?:

      Hello everybody,
      the upgrade to bullseye is planned for March.

      Best regards,
      Martin

      March has been gone now since two months.

      So I am getting the feeling there is no effort put into getting it lifted to current stable?

      Would be a pitty....

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

    • "UNIPISPI: SPI CRC2 Not Correct" - why?

      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

      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!

      @Martin-Kudláček

      Hi,

      sorry again for annoying. I am still conmsidering upgrading. Unfortunately my quastion about how I can see if it it ready for Bullseye has not been answered.

      From my point of view with the links I originally provbided it looks like it has not been upgraded up to now. Am I right here?

      Thanks& Greetings

    • Suggestion for IAQ re MQTT

      Hi,

      I use the IAQ sensor through MQTT. Working fine, really.

      Just one point:
      Could you improve the firmware so it will mark it mqtt messages as "retain"?

      Reason:
      When connecting to the mqtt topic the client currently does not get any information. When the retain flag is set the client will get the last information at least. Otherwise it has to wait for the next update.

      With "retain" you get immediately a status.

      Thanks!
