Topic: Throttling CPU
I read on this post about how to throttle the CPU down to 64MHz (for saving power when not used):
echo 64000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq # Set minimum CPU speed to 64 MHz
echo 64000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed # Set CPU speed to 64 MHz
This worked great on a Chumby One board I had, but caused an Insignia Infocast board to hang. At that time I figured it was due to some hardware difference between the Chumby One and the Infocast.
Recently however I got a chance to try this on 4 other Chumby One and Infocast boards (2 each) and to my surprise I discovered that all of them hang when throttled this way! So my original Chumby One board is the only board where this currently works. (I verified that it does actually throttle the CPU down to 64MHz on that board).
Does anyone have any idea why?
