Banana Pi Pro - 7" LCD Touch Display - How to enable?

[sgei]

Hello,

 

a few months ago I wrote a tutorial to enable the 7" touch display for Banan Pi and Banana Pi Pro.

Unfortunately the files (*.dts e.g. sun7i-a20-bananapro.dts) have changed and I don't know how to integrate the patches in the current armbian version.

 

Does anybody know how to do it?

 

Is there already a overlay to enable it?

 

Thanks.

Changes are not ours, but upstream. We are adjusting our patches all the time. (there you could also find some clues)

No, but I have some ideas how to proceed. First find out how references were changed - which is what makes most of the troubles here. Then make use of existing overlays and create one for this display - and search around before since it is possible someone already did it. Or for similar display.

U-boot integration - enable all by default or enable all but stuff in the config ... if things works normally with or without a display.

Hi Igor, hi all,

 

I invested some time in the problem over the weekend and was able to find a solution.

I also found a workaround for the shutdown/poweroff-issue.

 

Here is the link to the updated tutorial:

 

 

Now it would be nice to have a device tree overlay for this display.

 

@Igor, can you include the driver for the touchscreen by default (kernel config / not as module)?

 

Can anybody help to create a overlay?

Sure - send a PR to all affected config(s). I assume it does not break anything.

BTW. Great job! I still have your display around. I might test it when possible
