[Rpi 5] New Raspberry Touch Display 2

florent45 · November 28, 2024 at 5:44 PM

Hello,

I can't get Librelec and the new Raspberry Touch Dislay 2 screen to work on a brand new RPi5 4GB ...

The screen works fine with the latest Raspberry Pi OS version, but it doesn't react under Librelec ...
I tried the latest Stable, as well as the latest Nightly-Build in 12.0 and 13.0, but same symptom ... The system seems to boot well since I see my network but nothing on the screen.

If anyone has a clue or procedure ... I haven't found much for the moment ...

Thanks in advance

I believe the Touch Display 2 is natively portrait, and kodi doesn't support rotation through DRM so this is not going to work well even if you get the touchscreen working (presumably there are kernel commits missing).

Running RPiOS desktop, and using kodi21 from apt would support rotation I believe (but it's a less efficient render path).

Thanks for the feedback.

I tried forcing rotation by editing the config.txt and cmdline.txt files:

cmdline.txt: add "video=DSI-2:720x1280@60,rotate=90"
config.txt: add "dtoverlay=vc4-kms-dsi-ili9881-7inch"

These changes work fine under RPIos Lite, but Kodi still doesn't respond.
Apparently rotation via overlay was added in Kernel 6.6.63, I will test other parameters...

Don't spend too long on this. It's not going to succeed.
