How to enable DSI for Radxa Display 8 HD

#1

Hello,

I am trying to enable the DSI output attached to a Radxa Display 8 HD.

How can I do that?

I didn’t find any documentation online.
I am using Yocto factory installed.

Thank you

I don’t think Radxa Display 8HD is adapted on yocto, maybe you need to configure it yourself according to the dts in our Overlay repository.

Hello,

I can finally confirm that the Radxa Display 8HD is fully working without writing the additional dts file.
The dtbo is already provided, kindly, by Mediatek. You just have to flash the custom Yocto image with genio-flash passing the correct dtbo file at the command line. To enable the Radxa Display 8HD:

genio-flash --load-dtbo radxa-nio-12l-radxa-display-8hd.dtbo

to list all the available dtbo:

genio-flash --list-dtbo

you will find into the list the dtbo finename to use to enable the Radxa Display 8HD.

The display connected to the DSI bus turned ON.
I was able to see the Wayland session.
I need further work to enable touch.

Thank you everybody
