I am using the indi-sv305 driver on both a pi3 and pi4 with good success. I am not using Ekos, rather just PHD2 for guiding, local Astrometry.net for plate solving and AstroDMx_Capture for imaging. No issues. I used sudo apt install indi-sv305 after first adding the ppa per the INDI instructions for the pi3, but had to download and compile from github for the pi4. The only compile issues I saw were warning error messages that were not important. Some C programmers will use variables in functions where the sizes don't match if they know the data in the variable will never exceed the limits in runtime. It is a tiny bit sloppy on the compile side, but causes no real runtime error.

Just FYI, I am very happy with the performance of the SV305 as a guide camera on a 240mm x 60mm guide scope binning 4X4. Nice, crispy stars that plate solve with local Astrometry.net in about 15 seconds and make PHD2 very happy.

Sometimes, if you have messed about a bit, your camera may end up on /dev/video1 or some other number besides video0. This can be caused by something else already on video0, restarting indiserver or some other operation involving video devices. Usually, a reboot will reset things and your first instance of the indiserver calling the indi_sv305_ccd will put it on /dev/video0. If that is not the case, then you might have to change the configuration or find whatever is grabbing /dev/video0 first and move it.
