Hi everyone,
I searched the Internet but the help I found didn't work. I hope someone here may know how to fix it, here's the situation:
I have this ARM9 SAM9G25 which is accessed by its ttyS0. I want to disable all of the output, that was made during the U-Boot (v. 2010.06) boot, to decrease the CPU's load. Therefore there is the
setenv silent 1
Your U-Boot is too old.
parameter, which i put into the BOOTCMD string like:
#define CONFIG_BOOTCOMMAND " setenv silent 1;" \
"bootm "
and there is (as mentioned in the Readme.silent http://git.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=blob;f=doc/README.silen... ) the
As you see, patches was integrated in 2013. You are running an old U-Boot version, when silent was not supported. Please update to 2014.01 or (better) use the current git tree.
BTW (I'm not sure if this is related to this) in the referenced link there is the information, that u-boot sets the kernel command line to "console=" so that in the end there will be no output for the kernel too, but that didn't happen and it doesn't even happen if i force to boot Linux with "console=" in the default Linux command line string
Usually, it helps if you pass "quiet" to the kernel command line.
