We have just bought the new official 7" multi-touch display for RPI2 (https://www.raspberrypi.org/blog/the-ea ... i-display/
We've tried it with buildroot + qtbrowser, the video is good but we haven't succeed to get the touch working!
Any idea or any plan to support it?
I've got it working with the latest version from https://github.com/Metrological/buildroot-wpe
I just had problems with DT kernel. The kernel zImage-dt
built using the raspberrypi2_wpe_defconfig
didn't wan't to boot so I tried with default buildroot and it worked. Then I modified the wpe config to be more like the default:
The DT kernel can be then found in output/images/kernel-marked
. To enable touch screen support modify config.txt
Code: Select all
The generated sdcard.img didn't include the overlays so I copied them afterwards. And also manually copied the kernel from kernel-marked/
. The boot drive should look like this:
Code: Select all
# ls -la /boot/

The original repo didn't have post-build.sh
(anymore?) so I used post-image.sh
instead. I'm not sure which was the essential change in the config to make the dt kernel boot.
At least simple touches and multitouch works.
