Are you using the Rock64 or the Rock64Pro? It looks like a good alternative.
I am using a Raspberry Pi 3 B+ with Lubuntu 16.04 on a SSD with external Wifi (headless, controlled via VNC).
The setup runs great but the lack of USB 3.0 made me think of better alternatives.
The Pi 4 is not coming out till 2020…
What devices, similar to the Pi, are you guys running KStars on?
It should have USB 3.0 and be able to run Ubuntu (or Lubuntu, or Xubuntu… )
Is the ODROID-XU4 any good?
Greetings from Germany
I had the same problems and ended up using Ubuntu Mate 16.04 and (testing right now) Lubuntu 16.04 on my 3B+
Please not that in order to install one of each I had to put the card into a 3B and do an upgrade, otherwise the 3B+ refused to boot.
I could really use some advise as the auto focus issues I currently experience have already ruined two perfectly good nights and I do not want to spend another night trying to get it right.
Ubuntu Mate 16.04 on Raspberry Pi 3 B+
The Pi is running headless and I am connected via VNC
Canon EOS 5D Mark II
Canon EF 200mm f/2.8L II USM
The camera is connected via an active USB hub
No mirror lock
The settings in Ekos / INDO are standard AFAIK. The values for pixel pitch and sensor size are set.
I can capture an image, select are star and run the Auto Focus. It will go through a few steps and either be successful or not but that really does not matter because the stars will still be out of focus. I have increased the values for max travel and steps (as shown on the tutorial video) to no avail. The process will finish successfully with the stars still out of focus, decreasing the values for max travel and step will let the process end up unsuccessfully (and also out of focus stars).
The image takes so long to load on the Pi that the built-in LiveView is unusable. I even tried to focus in and out manually and I do spot a difference when changing focus but I did not get it right.
I have used LiveView on the camera itself to get it focussed as good as possible but I think it was not enough for auto focus to work properly.
Does anyone had similar problems and a solution for me? Is there anything I am missing?
Best regards from Germany,
I am having the same problems on the latest nightly, too.
Does it happen every time you try to autofocus? I got it to work several times but some camera operations randomly crash the driver and I had to restart the INDI server and Kstars to get it working again. Sometimes Kstar exited with no error message at all.
It did happen on the autofocus tab, capturing worked without any problems (aside from a "slighty" out of focus camera )
I am using the EOS 5D Mark II, if that matters.
I am going to try it again this evening, how can I see the logs so that I can provide further information?
I am experiencing the same issues and I was wondering if this has been resolved or if it occurs again for some strange reasons.
I have built myself the usb cable for a SkyWatcher HEQ-5 by using a FTDI TTL-232R-5V and a RJ-45 cable

Ekos / INDI reports:
2019-02-13T20:02:50: [ERROR] Error: Communication failed -> tty read failed, check connection: Timeout error
I have installed INDI (Ekos, Kstars…) by using the AstroPi3 script on a Raspberry Pi 3 on Ubuntu 16.04.5 LTS and I think I am on the latest version (sudo apt-get upgrade && sudo apt-get upgrade already done a couple of times).
Any help is greatly appreciated, I am trying to get this to work for the last three days.
