RPI4 freezing up during Polar Alignment refresh in Ekos

[k4kv]

Not sure if this is the correct place to post this inquiry...

Last night Ekos on an RPI4 would freeze after the Capture, Solve, and Slew portion when I clicked

Refresh.  It did this a number of times, even after several Reboots.  It said KStars/Ekos was using 29% CPU,

which seems like a lot!?

Anyone else seen this?

29% doesn't seem a lot to me. Without any more details, it's difficult to isolate the problem. Have you posted this problem on the indilib forum?

A starter question for you which might help people to narrow down on your problem!

- which version of KStars are you using on which OS on the RPi4 (and how much RAM does it have)?

Check the power supply/battery output and stability. RPi4 alone needs 3A. Insufficient Amperage often leads to RPi freeze. If you have a camera, guider, focuser, and filter wheel connected and driven by RPi it can easily become underpowered.

5-6 A should be available at all times. For cooled camera setups even more as they require 3A alone.
