Hi,
The target configuration utility does not support the Bookworm version of Pi OS. It does support the latest Raspberry Pi OS (Legacy) 32 bit version. You would need to boot the Raspberry Pi from a Micro SD card with that version.

The kernel image can be downloaded from https://www.raspberrypi.com/software/operating-systems/

Do you know where the problem is? Is it a fundamental incompatibility of the schroot installation in the new Raspberry PI OS, or is it more something of the Firmware Wizard not quite handling the connection properly?

Hi Rolf,

There are a few issues.  I think the ssl connection is failing because of the type of key required by the Bookworm version of Pi OS. It's possible this may be fixed by using a newer version of the Renci.SshNet.dll.

(LINX/LabVIEW/vi.lib/MakerHub/LINX/Resources)

The schroot runs OK on the Pi OS, but we will need a new .deb file because Python 2 is not supported.

For more information see this issue raised by @cycleworm

Thanks Andy

That helped it connected an I'm off and running. I hope they get Bookworm to work with it but for now its working with the legacy OS.

Is it working now with RBPi 5? It's not clear for me. If yes, can somebody summarize how to make a connection between LabVIEW (Target configuration) and a RBPi5? I still get the error "Ignoring Error: 5000 LMH-LINX.lvlib:SSH Smart Open Session.vi". I have 32-bit Bookworm installed.

Andy,

I read your response to this post since I was having the same problem as the author.

I was using Bookworm 32 bit version, but have re-flashed the sd card for the Legacy 32 bit Bullseye OS. 

I am also running LVCE 2024 Q1.

I am trying to connect with WiFi to the RPi IP address.  Will this work?

I get the same error of not connecting LabVIEW to the RPi 4B.

Is there anything additional that I need to do, or have overlooked?

This seemed like a strait forward process, but has failed me everytime.

Extremely frustrated,

Joel

Hi Joel,

It should work OK on Wifi with the IP address of the RPi.
Are you able to ping and connect by SSH to the RPi OK?

Please can you send the contents of the log file?

Andy.

[PokeChop]

Andy,

Yes, I can ping and access the RPi 4 with Putty.

Excuse my memory, but where do I locate the log so that you can review it?

Thank you,

Joel

Hi Joel,

You can open the log file in notepad by clicking the button at the bottom left of the target configuration window:
