So one issue that I have had for quite some time is that the SBIG INDI driver is based on a compiled binary driver file from SBIG, and while they have an armhf (32 bit) version, they lack an aarch64 (64 bit) version. This means that my SBIG camera works great on a Raspberry Pi 3, for which the system kernel is 32 bit, but if I want to use it on ODroid C2 or Rock64, where the kernel is 64 bit, then I need to use INDI and possibly KStars compiled in the armhf architecture (32 bit) instead of the aarch64 architecture (64 bit). You can see the issue here on the PPA, as the majority of the red x marks:
I posted on the SBIG/Diffraction Limited Website about this in January of this year and so far I haven't heard anything. You can see my request here (not sure if you need an SBIG forum account to view it):
