Hi community,
I use the 5.4.47 linux/yocto version with the imx8mmddr4evk build configuration.
With the available hardware I want to use a HD MIPI display with the QT eglfs platform or a SPI 240x320 display with the QT linuxfb platform.
The default configuration delivers eglfs but not linuxfb.
To solve the problem I added the folowing line in the conf/local.conf file:
PACKAGECONFIG_DISTRO_pn-qtbase = "linuxfb"
This ends in the rootfs with both libraries for eglfs and linuxfb. BUT only linuxfb can be used.
My application, I used before with eglfs, don't start any more with eglfs.
Now I have two QT lib folders for two displays as workaround, but I hope there is any other solution available.
Any idea?
Best regards
Cedric
Hello Cedric,
The MX8MM does not support QT EGLfs, but it looks like you are out of this problem.

Hello Bio_TICFSL,
indeed I never had any problem to use eglfs with the imx8m mini till I also want to use linuxfb.
I'm surprised to read it isn't supported.
So the only supported interface is wayland?
Best regards
Cedric
Correct! also LinuxFb neither is supported
