I am experiencing an issue with my touptek camera.
When taking exposures, it will start the exposure and sometimes never finishes it, exposure timer counts down, and upon it reaches zero the image doesn't get downloaded.

Aborting the exposure and restarting it a couple of times does resume and complete it correctly for a few exposures, but the issue than sticks it's head up again.

Log file is attached.

Nothing?
This is really frustrating

I got an updated SDK from Touptek so we'll see. I also asked them about a few other technical issues with the SDK and awaiting their reply.

Great!
Thanks, hopefully it will give some improvements.

In case it is not specific to a particular driver, I have this problem from time to time. ASI071 camera. Last nights session for example was a failure. Not using the scheduler just selecting 60 x 60 second exposures in the camera panel. After 17 exposures it stopped making progress, kept counting down to 0.01 second remaining, then restarted the count from 60 without creating an image or incrementing the completion count. The logging had been focused on an issue with my roof driver but an extraction is below. It shows the transition from the last image collected #17 to when it gave the appearance of just looping.

I'll try and catch it again and what can be seen resource wise with the multiple use of /tmp.

Then later on tried testing it again and got a pop up dialog:

Ok so I pushed the SDK update anyway, not sure if this will fix anything for your case. I'm still awaiting their response on the slow video FPS.

Okay, I think I got the SDK installed, not sure however.

I did a test in Ekos capture module, but still had a few 'stalls'

Like I mentioned, I'm not sure if I did everything right with the build, I'm far from a Linux expert
