Getting DSI LCD and HDMI output working with Qt embedded on Raspberry PI 3B+
I have build a boot2qt image for a raspberry PI 3B+.
It includes kernel version Linux b2qt-raspberrypi3 4.19.71
Raspberry firmware: 0e6daa5106dd4164474616408e0dc24f997ffcf3
The DSI display is phisically working: in the early phase of the boot I see the console on it.
I have added the follwing to the kernel's boot parameters:
Added the following to the config.txt:
But still I have only a /dev/fb0 and the Qt applications does not see the DSI between the QGuiApplication::screens() list
Any help would be highliy appericiated!
