I used the alternative approach you suggested and it worked with no more issues. I had originally tried on both Mac and Windows machines: first formatting the microSD FAT32 and then extracting the zip to the microSD as in the instructions. I ran into the same boot issues with both methods. On closer inspection however, these errors seem to come up regardless of whether the OS successfully boots or not so I believe it is unrelated. Perhaps the booting issue had something to do with the formatting of my microSD although it is not the same one I used for NOOBS.
Thank you again for the assistance. I have another broader question that may perhaps be answered in another category, but since I’m here already…
I’m hoping to use info-beamer on 2 Raspi 4s for a dual-channel HD video projection (art installation). As I said before, I have very little experience with Raspis, so I was hoping for something fairly simple to implement and use. I have been playing around omxplayer-sync and networking the two Raspis using a cross-over cable. I’m not entirely happy with this solution as it seems to lose sync and is not entirely easy to implement and control.
Am I correct in thinking that this is something that info-beamer would be good for? Could I get robust sync playback between 2 Raspi 4s and seamless looping? I’m working with two Raspi 4s playing back a single HD video file each. It would be nice but not necessary to also be able to up to playback two 4K videos in the same arrangement.
My apologies for the long follow-up questions. Thanks for you time.
