Hi,
I am using Android lollipop in firefly RK3288. We are connecting firefly to a HDMI touch screen.
Sometimes in few of our screen the visual goes out of screen and we use Settings->Display->Screenscale option to bring it to normal. The issue is after reboot the scale settings are getting reset.
How to make firefly to remember the screen scale settings.
You can build a kernel with a default screen scale that you need.
In SDK/kernel/drivers/video/rockchip/hdmi/rockchip-hdmi.h you can set the screen scale 99%, 95% etc. that fits your needs.
It should also be possible to change the screen scale in the build.prop file but maybe someone else knows how to do it.
Hi,
The issue is we have different screen scale for different monitors, it is impossible to make a change in the kernel for each screen.FF already has a screen scale settings but the settings are not stored thats the problem.
Hi javasanthan
Yes,we designed the screen scale setting not stored.
If you want to stored , just save the settings ,and then read the settings ,set it to work after the system is ready.
that there is no much work to do .

Hi Isle,
I had the same need to pre-set the screen scale and resolution.
Could you please elaborate a little bit details on how to “save the settings ,and then read the settings”? Is it done in App level or do I need to build it into the system.img?

Hi Isle,I had the same need to pre-set the screen scale and resolution.
I actually followed the instruction above to set the config in SDK/kernel/drivers/video/rockchip/hdmi/rk-hdmi.h to tune the default scale and hdmi_mode and re-build the kernel.img, system.img. While it does nothing after I flashed the new image…
