i am trying to get a clean boot.
I have created a service with systemd that loads me a video at boot, but I cannot eliminate all debug messages at boot, and especially once I start to eliminate the blinking cursor and logging.
In short, I would like that no message would come out on HDMI, black screen, in order to view only my presentation before the desktop.
i tried with some parameters in extlinux.conf
append earlyprintk console = ttyFIQ0,1500000n8 quiet consoleblank = 0 rw init = / sbin / init rootfstype = ext4 rootwait root = UUID = f4dd7250-134a-4fc8-963f-b7137db816d3
But it doesn’t take them into consideration
I don’t know whether to put something in uEnv.txt as well, but I can’t find any documentation on the parameters, it seems that the official Debian Buster tips don’t work here, or have been disabled.
Anyone know how to have a clean boot?
Thanks to anyone
