kernel 2.6.37 XM 1GHz ?

Hi everyone,

I'm having a problem enabling 1GHz on XM board.

I built angstrom-2010.x out of the trunk and have 2.6.37 kernel (R100)
successfully built.
I checked that u-boot identifies the board correctly (XM) and passes
mpurate=1000 to the kernel arguments.

But when I boot the board with this kernel I see following relevant messages:

[ 0.000000] Kernel command line: console=ttyO2,115200n8
mem=80M@0x80000000 mem=384M@0x88000000 mpurate=1000 buddy=none

[ 0.000000] pid_max: default: 32768 minimum: 301

Looking at the /proc/cpuinfo I can confirm that cpu has 503 BogoMIPS,
and this means 600MHz if I understand correctly.

Does someone have an idea what I'm doing wrong ?


opkg install cpufrequtils ; cpufreq-set -g performance

opkg install cpufrequtils ; cpufreq-set -g performance

Thanks Koen,

as usual, you are completely right.
