I can't answer your question directly but here is my experience.
I run indi on a PI 3B+
I run kodi (media player) on a Tinker board. It has run for months 24/7 with any issues, no reboots..
The Tinker Board is great.

However I use Raspbian on the PI and Tinker OS on the Tinker Board.

I have not yet tried indi on the Tinker but may do one day.

I guess you my need to go the source build route to get the latest versions of indi etc. Also true fro Raspbian on PI.

I am consitering upgrading my indi PI to a Gigabyte Brix so I can run the intel builds of indi etc.
It does use more power though.

If it fails to work, you can make a media player out of it.

Thank you for your help and support but I am now working on 1.7.6

I captured the logs for 1.7.5.

Rebuilt and installed 1.7.6 libindi and 3rd party drivers.

And to my surprise it now works. I can see the scope moving in my garden.

Logs look OK.

So I have not raised a bug report.

I am wondering if I had a mismatch between 3rdParty and Libindi versions?


I suspect an intermittent fault in my brain to fingers interface. It is a shame I can't supply the log files for that.

Thanks yet again for the help on this forum.

I think I am sorted now.

I have downloaded and build indi 1.7.5 on the RPI and it looks like it is ready to go.
I can control the mount and cameras again.

So it looks like 1.7.6 won't run on the RPI at the moment.

Hi, I have been having great results with Kstars and Indi, but I am now in version number confusion.

I decided to upgrade and now have more problems than before.

I am using Kstars onUbuntu on a laptop and libindi1 on raspbian on Raspberry PI.

Apt-get update on Ubuntu pulls down libind1 1.7.6

The only instructions on this site that I have found suggest 1.7.4 on raspbian.

My current problem is various drivers crashing with an EOF error, just after reading an xml file. The files do exist in the correct place.
This was reported as fixed a long time ago.

I am happy to download or Git source and build but getting stuck on which versions to use.

Please can someone recomend good versions to have on Ubuntu and raspbian?

Well that was easy. The above link did work for building Indi 1.7.6.

Hi,

I am having great success with libindi on RPi

My current setup RPi3B+, Raspbian stretch, libindi 1.7.4, Laptop Ubunu kstarts 2.9.x libindi 1.7.6 (was 1.7.4), tp-link travel wifi router.

I do have a few quirks that I hope will be fixed by an upgrade to 1.7.6 (for example the auto exposure for flats that was fixed a while ago).

I can only find 1.7.4 on this site.

My google searches are turning up very old instructions.

Can anyone offer some pointers as to how to get 1.7.6 installed on Raspbian.

Thanks.

I think I was worrying unduly, I was standing in the cold waiting for 10 second test images and it seemed to take forever. (I am an armchair astronomer after all)

So I have done some timings to put science ahead of guess work.

Raspberry PI-Raspbian-Indi and Laptop Ubuntu Ekos etc. H18 via USB2. Delay=0.

10 x 10 seconds took 212 seconds (53% photons lost)
10 x 300 seconds took 3145 seconds (5% photons lost)

Laptop Ubuntu Indi+Ekos etc. H18 via USB2. Delay=0.

10 x 10 seconds took 150 seconds (33% photons lost)

10 x 300 seconds took 3049 seconds (2% photons lost)


So for realistic exposure lengths, there is a small but not too big penalty to using the PI.
There is of course the advantage of less cables etc., that is I want to achieve.

And yes I also use a 10 second delay for the camera to dump download heat also heavy dithering.

All in all nothing to worry about.

Thanks to all for suggestions.
