Hi there,
I am currently in a project of uniting PiFinder (pifinder.io) and Stellarmate. This is not possible at the moment because I wait for the PiFinder to be elevated to Bookworm. I'll report on succeed (you can follow on PiFinders Discord channel, if interested:
"PiFinder in Stellarmate" on Discord
. My discord name there is HeyApos 
. But that's another story.
Back to topic:
That's why I currently dual boot Stellarmate and the PiFinder on the same hardware and a Raspberry Pi HD cam is attached (datasheets.raspberrypi.com/hq-camera/hq-...ra-product-brief.pdf) It works fine with the Pifinder (which uses a pyhthon library and another OS version). So the camera itself and hardware is OK.
The new Stellarmate 1.8.1. claims to support the (official) Raspberry Pi cameras with Libcamera. I know there had been a lot of work by Jasem and others to get this work Thanks for that. I tried to carefully read here and understand how to debug this.
Problem:
When I select the LibCamera driver in a new SM profile, the profile does not start at all.
- Stellarmate App v2.6.80 (Android) - also tried with iPad
- Stellarmate OS 64bit 1.8.1.
- Drivers: Telescope Simulator and Raspberry Pi Cam HD (LibCamera)
Any Idea, what I am doing wrong?
Logging:
Dmesg gives me nothing. And the indi log dir is empty. the other log files I attached.

I followed this bug description: github.com/raspberrypi/picamera2/issues/502 and the test python code gives me the following, so this seems to work.
