[SOLVED] Waveshare DSI 7.9 Touch display on Moode 9

[popeye65]

Hi
just upgraded to latest Moode 9.0 release. Unfortunately my solution for running a local Waveshare DSI 7.9 display on 8.3.9 is not working anymore.

But here is the solution to make it working again:

The necessary LCD drivers are now included in the Bookworm release, no need to install drivers

Just need to enable it in /boot/firmware/config.txt

Code:

$ sudo nano /boot/firmware/config.txt

insert

Code:

dtoverlay=vc4-kms-dsi-waveshare-panel,7_9_inch

and save.
Since this display has portrait orientation one need to change it for boot messages:
Edit /boot/firmware/cmdline.txt

Code:

$ sudo nano /boot/firmware/cmdline.txt

insert this in front of the command line:

Code:

video=HDMI-1:d video=HDMI-2:d video=DSI-1:400x1280e,rotate=270

save it. after a reboot boot messages appears in landscape orientation
...

Hello Felix, thanks for your post, I have the same display (HDMI in Stealth V3) but cannot even get the console boot messages to work in landscape mode using those settings. Could you please post your complete cmdline.txt and config.txt ? I suspect I have something wrong, despite starting from 9.0.1 image.
