Summary0002213: Skychart Version 4.2 "Access Violation" message box when connecting to INDI Telescope
DescriptionRun Skychart with the INDIstarter app active and connected to INDI (setup for Telescope, CCD, and Focus simulators in this case) and with the "Observer tools" Toolbox opened. When I then try to "Connect" the telescope a message box pops up with the following message "Access violation. Press OK to ignore and risk data corruption. Press Abort to kill the program." Pressing OK does nothing (tried several times) so pressing "Abort" will shut down the Skychart program which is the only way out.
Steps To ReproduceStart Skychart (Cartes du Ciel)
Start INDIstarter and connect to the INDI server
Open the "Observer tools" (Use F1 or the "View" - "Toolbox" - "Observer tools" menu)
Click the "Connect telescope" icon in the Skychart toolbar (or use the "Telescope" menu)
In the INDI driver window that pops up click the "Connect" button on the lower left
At this point the message box pops up and the only way out it to click "Abort" thereby closing Skychart (basically a crash).
TagsNo tags attached.

I was able to reproduce this on a Raspberry Pi 4 4GB running Raspian OS using the same steps as outlined above. The Tinkerboard and Raspberry Pi were also updated to all the latest updates from "apt-get update" and "apt-get upgrade".

This is a know problem with the toolbox script on the ARM processor that as no solution for now, see 0002132

The best is to not use this tools with this processor.
Use the "Connect Telescope" button in the main bar without the "Observer tools" and it work.

Thank you Patrick for the followup and information. I had not seen that. This is unfortunate as I was wanting to use the "Observer tools" as a way to be able to move the telescope with the button interface. When I try to use the move buttons in the INDI panel my AP900 mount will not move (perhaps another bug it seems?). I use the Astrophysics Experimental driver. At one point while trying to move the scope with these buttons in INDI I had a high speed run away and was thankful I was able to disconnect the telescope power just in time to avoid a pier crash. In KStars/Ekos it all works fine.
I am trying to use the Skychart/CCDCiel software for semi unattended imaging. These are wonderful programs and thank you for all your hard work!
