As previously established, I have some older official 7" displays, including one where the touch functionality is [cough] non-optimal.
OK, it's broken, but the display works fine, it's one of the really early ones, not complaining #JustSaying.
So I want to re-purpose it. I connected in a Pi4 running bookworm lite which runs a glorified status display via the framebuffer (so no X11, no Wayland) but I am using the vc4-kms-3d. Tweaked my usual network stuff (turn off ipv6, disabled some unneeded daemons) and all was well.
Then I mounted it in a Pimoroni Pibow touchscreen frame. I have a few of these, and they are nice, and there are no issues with adding HATs etc irrespective of the model of Pi you connect. Unfortunately, there is one drawback, in that the display is effectively then upside down. Can't flip it around, because if you do, the frame stand isn't in the right place, there are cutouts around the display's connectors which make it awkward, etc.
Now, if I was running a desktop, I could easily fix this. But I am not. So I can't. The original advice was to use lcd_rotate in the config.txt file, but I believe that is now deprecated (hey, things change), and from information in a post made by 6x9, it doesn't work with vs4-kms-3d anyway.
So I haven't tried it, since they do know better than me (as has been proven in the past!).
So, given that, how do I persuade my display to flip 180 degrees?
I'm guessing that there is something I could add to cmdline.txt, or config.txt to achieve what I want, but a read through the documentation describes the lcd_rotate as "legacy". Ideally, I would like to do it the right way
Thanks
