Hi there, member of the balenaFin team here
The issue is by no means abandoned and work is being put to solve it. To give you some context, the pi-gen tool we forked from the rpi foundation does only userspace manipulation, so we had to figure out on our own how to handle kernel modules manipulation (and our own pipeline for balenaOS is so architecturally different that atm is of no use for raspbian, althought there are plans to investigate how to share more of that pipeline for the fin raspbian releases in the future). While I can’t share a precise ETA, I can assure you we are actively working on this and we expect to have at least draft release images in the upcoming couple of weeks.
the dimmed red light on the RGB led is a separate issue that is related to the specific driver configuration and is shared between balenaOS and raspbian. It looks like a regression and I’m personally the team member that is investigating it atm. I will make sure to keep this thread up to date on both topics.
