[U-Boot] Antw: Re: U-Boot doesn't silent the output

Now that I'll have in the board header file the lines 

#define CONFIG_EXTRA_ENV_SETTINGS  \
"silent=1\0"

and it works :) I really feel happy about this, thanks for your help! The output is disabled during U-Boot sequence, but returns when the kernel starts. I didn't expected that Linux is not influenced by this, but it's alright ATM. 

Anyway I wonder why the "setenv verify n" worked with the  BOOTCOMMAND but the "silent" didn't. Should I shift all the commands from CONFIG_BOOTCOMMAND to CONFIG_EXTRA_ENV_SETTINGS to be sure all the commands are really executed?

I really don't know the reason why Linux keeps talking during boot when using "console=", whereas "quiet" and changing the loglevel is working. I already asked in some forums about this, but it was as strange to them as it is to me - strange because it's a vanilla kernel I'm using, so the only thing that came to my mind is that this function is just not included into  v. 2.6.3.9.

Thanks again for your help!
