smartReflex testing

Hi Ran,

You can test whether the smartReflex is enable by the following commands:

cat /sys/power/sr_vdd1_autocomp
cat /sys/power/sr_vdd2_autocomp

Also the following site should be useful:

Hi Tsvetolin,

I think that a better approach for testing would be to check if the device do its job, i.e. trying to change the frequency and see if the voltage changes too.
Something like this:

target$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
800

target$ cat /sys/class/regulator/regulator.3/microvolts

1200000

target$ echo 700 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
800

target$ cat /sys/class/regulator/regulator.3/microvolts

1187500

What do you think ?
I would like to understand better what is the meaning of regulator.0 , till ... regulator.7 in OMAP ?

Thanks

Ran

Hi Tsvetolin,

Are you familiar with the meaning of regulator.X (X number) ?

What is each regulator.X number represent in OMAP ?

Thanks

Ran

Hi Ran,

I'm not familiar with mechanism of regulators but as I know the regulator.X setting values of the TPS65xxx power management chip registers which reflects to the omap power supply voltage and etc.

I am using TPS65xx ,

Where can I find what each X number refer to with TPS65X ? 

Best Regards,

Ran

Hi Tsvestolin,

Is any of the above mentioned methods, truly tests the i2c interface of the smartReflex ? Is there any document or wiki about smartReflex testing ?

Thanks,

Ran
