Why doesn't U-Boot disable the console output

I have this system which is accessed by a serial Debug Port. I want to disable all of the output, that was made during the U-Boot boot. Therefore there is the

setenv silent 1

parameter, which i put into the BOOTCMD string like:

#define CONFIG_BOOTCOMMAND " setenv silent 1;" \

"bootm "

and there is the

#define CONFIG_SILENT_CONSOLE

command, neither one is working (the lines printed out are still the same and the boot time didn't change). Does somebody see the error ?

Solution

  • U-Boot is doing exactly what it should (silencing the output) with the following command:

    #define CONFIG_EXTRA_ENV_SETTINGS \

            "silent=1\0" \
