That is the log file.

That's the KStars log, which doesn't help here as it only sees the ASI driver, not EQMod. Would need logs from the INDI server why starting the EQMod driver fails.

That is another file . I think it reads something about EQmod mount . 

That one is similar, the only mention of EQMod is that your Ekos profile correctly expects the EQMod mount, but the INDI server doesn't have one as it hasn't loaded the driver (or it has crashed). As said, we need the log from INDI server itself to see why. The INDI web manager probably does one somewhere as it starts the INDI server, but I haven't used it so don't know where. When running the INDI server manually from command line, you get it directly on the console.

".....When running the INDI server manually from command line, you get it directly on the console......"   How can I do this ?

Make sure the indiserver started by INDI web manager is stopped first and then run command "indiserver -v indi_asi_ccd indi_eqmod_telescope"

If you get an error about not being able to bind the port, that means the other server is still running.

I get this in the command prompt:

Thanks, that explains the cause, the EQMod driver is compiled against a different version of the main INDI library than is installed in your system. So one or the other has been upgraded since it started before the reboot.

To fix that you could either see if there are more upgrades available which might bring them in sync or rollback to an earlier version somehow or compile both the INDI library and drivers yourself which guarantees they are compatible.

Btw. no need to run indiserver as root with sudo, regular user works too.

What you think , is Stellarmate better system for this job? Will I have similar problems with it?
Where can I search for upgrades available about INDI library , EQMod driver etc.?

NO, stick with Astroberry, Stellarmate is even more prone to issues, and it’s slower too, Astroberry is free and better….although my EQMOD mount will not connect on either system….

I will format the sd card and make clean instalation of Astroberry . Will see what wil heppen.Should I update some drivers or softwares in Astroberry after that ?

Absolutely. The present image is quite old, and there are many improvements on the repositories. I would suggest sudo apt update, and then sudo apt full-upgrade. Be prepared to wait for a lot of changes including to the RPi Linux kernel and so on!
The only ‘special’ change I have made to my running Astroberrys is to replace the flawed FireCapture version with the latest Beta version (2.7.05 beta for the RPi) for planetary captures of Saturn and Jupiter with less glitches than the ‘stable’ version that comes with in the Astroberry package.
