RPI3 official touchscreen / HDMI is not working

[clementlgl]

I'm trying to work with Official Raspberry PI 7" Touchscreen and the latest branch (Zeus). When I build rpi-basic-image with rocko, the psplash is displayed. But the same image on Zeus, the touchscreen display just the 4 raspberry and the kernel boot.

I have connected a display on HDMI and I have the same result ...

I work with raspberry Pi 3 B

Have you the same problem ?

Thank you

Hi @clementlgl ,

It seems you have the same problem as https://github.com/agherzan/meta-raspberrypi/issues/500

I think the variable DISABLE_VC4GRAPHICS = "1" solves your issue.

FYI, here is my configuration for the rpi3 and it works fine:

I don't have a screen to test. It would be nice to see if this happens on rPi4 as well.

I dont test zeus but on master pi4/vc4graphics work fine with weston/wayland and pi3 works ok with eglfs/userland graphics, I did see it stuck with boot logo with vc4graphics

Thank you for your answers.

Indeed, with DISABLE_VC4GRAPHICS = "1" it works ! But with sysvinit the psplash do not work, I switched to systemd.
