Hi, I'm trying to enable an analog display, the things I've added to my config.txt are below
enable_tvout=1
And
dtoverlay=vc4-kms-v3d,composite
As well as
vc4.tv_norm=PAL
in cmdline.txt
However when booting, the screen on the display shows the rainbow image, then flickers white, a second later the raspberry pi logo splash screen shows up for a split second and the screen goes black with nothing else. I read somewhere that the white flash is the pi deciding not to use that display, but what else do I have to change so it does? I've tried changing the config.txt to read
dtoverlay=vc4-kms-v3d,composite=1
And
vc4.tv_norm=PAL video=Composite-1
to cmdline.txt
Like I saw someone do online but that hasn't worked either.
