I've just started having a similar problem. I'm running everything on a Tinker board a and my imaging camera is a Canon 100D with a QHY5L-IIM for guiding. The problem just seems to have started with the latest Indilib release, because prior to this everything worked flawlessly. However, now, I can collect images (using either CCDCiel or KStars), but as soon as I start looping images with the autoguider, the main imaging process hangs. The message that appears is that the image is downloading but it never completes and so the Canon eventually times out. However, the only way to get the Canon to work again is to power it off and remove the battery. All of which means that I can do no imaging at all. I assume it is a conflict between the QHY and Canon drivers, but I've no idea where to go from here.
