'Silent' boot

Software
1

Hi All,

It’s not a big deal but it would be a nice to have…
Is there a way to boot Zynthian without all these codelines flying by
before showing the actual bootscreen…

Thanks

This is the default for V4 & V5, but boot log is enabled for “DIY” kits to help with diagnostics.
You can change it easily.

Found IT !!!

Thanks

Unfortunately the changed setting in the Cmdline.txt are overwriten to original coldboot.
So the silent boot is not permanent. I see the same thning happening when changing the bootscreen/picture

You have to do this modifications from the webconf, @Rotil66 .

Look into the hardware->options submenu.

It’s commented in the wiki:

=>Section 4.5

Ok thanks, will take a look

Is there any info on how to use this custom config/boot option.
Just entering the command is not working

What do you enter? What is the result in the config file?

To get a silent boot I have to change
console=tt1 to console=tt3 in the cmdline.txt

As far as I understand for the info on the web.
This works but is not lasting after a coldboot.

Also I would like to have my own startup picture. I can change it but this is also not lasting after a coldboot.

the last thing which obviously isn’t that easy, is that i can’t get a good working display.
At the moment I have a 5" 1024x600 screen.
But the touchoverlay is off and probably on 800*600.
sorry for the many questions

Any tip on how I can do these things??

thanks!!!

If it is an HDMI screen, then you can put into the bootloader configuration HDMI_DELAY=8 or a different number than 8, which you may have to try out.
This example begins the output of the HDMI video signal 8 seconds after the start/restart of the Pi, which then is realtime and not delayed.
See documentation here https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#HDMI_DELAY
And how to mod the eeprom bootloader config:

thanks, but it’s a DSI display
so I assume this doesn’t apply to this screen.
