Raspberry Pi OS - Bullseye

oozeBot

Curious if anyone else has installed Bullseye on their Duet machines yet? I spent some time this morning testing it out. Overall, it's been successful. The only thing I've run into so far is hardware encoding for the webcam isn't working as OMX and MMAL has apparently been depreciated in favor of V4L2, which will take time to implement..

@oozebot There's a pretty experimental DuetPi build based on bullseye on https://pkg.duet3d.com/testing/ but I haven't been able to get the RPi display working yet (using the DSI cable, not sure about HDMI). It just turns white when it's supposed to start the GUI and I don't know yet what is causing that. The DuetPi-lite build appears to be working nicely, though.

I also just installed the 64-bit version of Bullseye on a machine. Running a test print now, but so far, so good..

@chrishamm - I haven't run into that since we don't use displays directly connected to the Pi.

I got aarm64 bullseye running on my RPi4b+ today, as well.

I used the 2021-10-30-raspios-bullseye-arm64.zip image (from here) and flashed to an M.2 drive. After booting, updating, enabling SPI and increasing the buffer size (per here), then added the unstable sources.

After copying back my configuration and doing one last reboot of SBC and Duet 3 Mini 5+, I was greeted with a working printer once again. Running a test print right now to see how everything is working.

The only issue I see right off the bat, is the DuetPi management plugin, when attempting to start via 'Settings - Machine-specific - External Plugins' complains that:

Failed to start plugin:
InvalidOperationException in StartPlugin: Cannot perform command because the plugin service (root) is not started

however, systemd reports:

but I cannot glean any information beyond that.

Let me know if I can provide any further information.

@omtek Check duetpluginservice-root as well

@chrishamm That was the problem!

pi@legionXY:~ $ sudo systemctl enable duetpluginservice-root
Created symlink /etc/systemd/system/multi-user.target.wants/duetpluginservice-root.service → /lib/systemd/system/duetpluginservice-root.service.
pi@legionXY:~ $ sudo systemctl start duetpluginservice-root
pi@legionXY:~ $

Success!
