Hi davemilter,

Try to use the next parameter in U-Boot cli:

mpurate=1000000000

Or fix "if" statement in the "arch/arm/plat-omap/clock.c" file "omap_clk_setup" function:

if (mpurate < 1000) mpurate *= 1000000;

To:

if (mpurate < 2000) mpurate *= 1000000;

P.S. I wonder why this code hasn't been fixed yet?..

Cheers, Max.

Hi,

when I boot default kernel, and did cat /proc/cpuinfo it shows something like 980 or 986 (not rember exatcly, but very close to 1000) in  BogoMIPS field, that was 2.6.32 kernel (and as I understand it was build with help of openembeded).

Then I downloaded openbedded and built linux-omap-2.6.37, boot, ran $./cpufreq-set -c 0 -g performance and got BogoMIPS        : 851.45

while

$cat /sys/devices/system/cpu/cpu0/cpufreq/ cpuinfo_cur_freq 1000000

This mean 1GHz, right?

so I wonder where is near 100 BogoMIPS?
