Hardware: iMX8MM-EVK + MIPI-DSI to HDMI
Platform: uboot2017 + Linux-4.14.98_2.0.0 from yocto 2.0
Display is okay with uboot up, and display setting through commandline (video=1280x720-32@60e) is fine during kernel loading. The "OpenEmbedded" loading screen can been seen, and then display is shutdown without wayland desktop.
More than three LCD monitors are used for testing, only one monitor can display wayland desktop.
It's appreciated for any comments and hits. Thanks in advance
