Hi there,
I have this display I would like to use to show an image or a video with a Raspberry Pi 3B+ running Raspberry Pi OS Lite (bookworm).
![Image]()
gives me:I don't have a , maybe because I installed a minimal version of the Raspberry Pi OS, and I don't have an HDMI display connected.
I have a available, but returns .
With smaller files, cat does not complain, but nothing is showing:.
Anyhow, I would like to have that screen as a way to display an image or a video, and even as a console if that is possible.
I have made a few modifications in:
doesn't say anything bad, but nothing happens on the screen.
doesn't show any error, but nothing can be seen on the screen.
How could I find where I failed? Are there any commands that could help me find one of the failure root causes?
Many thanks for considering my request.
