Apologies if this has been raised before. I recently bought a RPI4 and loaded up the latest RPI4 compatible version of Ekos. I connected everything up and took it for a spin. Everything was working fine, until I tried to capture an image with my guide camera (ASI120MM Mini). I tried to capture a 1 sec image. It counted down, then got stuck at 0.01 sec.
I changed USB ports, cables etc. I then swapped back to the RPI3 and it worked fine, so there appears to be a problem with this camera on RPI4.
Sky-Watcher Black Diamond ED80
Meade 8" LX-90
Sky-Watcher EvoGuide 50 (guide-scope)
ZWO ASI290MC (non-cooled primary camera)
ZWO ASI120MM mini (guiding)
Canon EOS 7D
I had the same experince Friday night, first time I used my RPI4 with the latest Stellarmate/KStars version. The ASI120MM Mini (guidecam) attached to my new ASI533MC Pro (first light) - no pictures from the 120MM. I then attached the 120MM to one of the USB2 ports on the RPI4, same issue - no pictures.
Then I tried to do some streaming, that did the trick, I was now able to get pictures from the 120MM. That's what I did the rest of the evening if I rebooted Stellarmate (first time setup).
Looks like clear skies tomorrow evening as well, then I'll check if I can do the same with the 120MM attached directly to the 533MC.
Otherwise, it worked flawlessly, HEQ5 mount, GPS unit, 120MM mini, 533MC, ethernet to my laptop in the heated garden shed
Shooting right now, I have had issues with the 120MM mini several times tonight, restarted SM, unplugged the camera etc. to get it running. There’s no apparent way to make it work, streaming does not seem to work every time.
I tried to enable logging, but didn’t work - just realized I needed to enable it in the “Logs” menu
I have just installed SM 1.5.0 on my RPi4 and Kstars 3.4.0 on my laptop. Testing if everything is ok, so far no problems capturing from either the ASI533 or the ASI120Mini.
I've also tried to use Astap for plate solving, used an M82 image taken with the ASI533/200PDS setup - no problems, it's lightning fast! I've used ansvr so far, it struggles plate solving the same image.
