Seems like the RPi 500 doesn't like BASIC Engine that much... 😝
I get constant XHC-CMD err: 4 type: 11 [01:00] 0.00 000000:02
errors.
But one of the messages that appears is:
The installed operating system (OS) does not indicate support for Raspberry Pi 5
Update the OS or set os_check=0 in config.txt to skip this check.
As said, I tried that, and only got a blank screen. Reading people with similar errors on the Octoprint forum (the only reference I found for these kind of errors) it seems that it's because it's not a specific build for a Raspberry 5? (500 in this case).

I don't know if there's anything more I can do. I hope it can be fixed. Cheers!
