[U-Boot] Splash Screen

[U-Boot] Splash Screen

[Schmid Alexander]

Hello,
i have U-Boot running on MPC5200B! The U-Boot console output is on display!
Now i activated the splash sreen support, and it works!
But now I`m wondering, if I have a problem and have to do something in the
U-Boot console if I get there!
Because when i press a key (between the 3 seconds of autostart) the splash
screen picture stays there, and I don`t see any console output!

Has anyone an idea how I can solve that? I thaught about e.g. pressing ESC
and then I`m on U-Boot console or so?

Thanks

You, of course you do. It just depends on how you set your I/O
channels (stdin, stdout and stderr).

Try typing (blind):

	setenv stdout lcd

(followed by ENTER). What happens?

You have to assign the I/O channels to the devices you want to use,
that's all.

Of course there's no reason for it, it's just our policy.

When I type blind, the U-Boot acts normally( e.g reset or run bcmd_flash).
But nothing happens if I do a"setenv stdout lcd".
What could the reason be?

Maybe you should use "vga" instead of "lcd". Try:

	setenv stdout vga

OK thank you. It works. I played with the variables a time ago, and thought
today, the whole morning, sdtout lcd sounds a little bit strange. But
unfortunately "vga" was not in my head!
Do you know were I could place the setenv stdout vga, that it will be
automatically loaded when the 3 seconds autostart get interrupted from a
key?



Thanks very much.

Anatolij

Enable CONFIG_PREBOOT and "setenv preboot setenv stdout vga" ?
