Hi,
My name is Rajiv Nishtala and I am PhD student at UPC, Barcelona.
I am trying to run some benchmarks on the arndale board and measure the power reading from it.
is there a way to measure the power from the board directly, I tried using the wattsup .net meter and was not successful.
At the moment, I am trying to use 32 system configuration registers, sys_cfs to measure the power, but the method seems to be very difficult for me. Would you suggest using any other technique?
From the /sys/ folder, i found the following:
/sys/devices/voltage-regulator.5/regulator/regulator.1
more uevent OF_NAME=voltage-regulator OF_FULLNAME=/voltage-regulator OF_COMPATIBLE_0=regulator-fixed OF_COMPATIBLE_N=1
But i am not sure what voltage it is referring to. Could you please shed some light here.
Thanks. Rajiv Nishtala
I haven't worked much on power measurement on Arndale, but there are others in Linaro who are actively using Arndale board for various power management activities. Ccing the linaro developers' mailing list where you can get some interesting information.
