Hello,

Is any way to use the full cpu potential from the board.

I have tried the environment settings from one of the threads where gpio-regulator-1.3v is introduced but without success.

Thank you

Ok then, here is my take on the matter.

 

You have to build the new image or wait for @Igor

 

* Apply the patch described on the thread

* Change the regulator like this:

 

            reg_dcdca: dcdca {
                regulator-always-on;
                regulator-min-microvolt = <810000>;
                regulator-max-microvolt = <1160000>;
                regulator-name = "vdd-cpu";
            };

 

* rebuild Image
 

There you have it:

It is fine.

 

For the torture test, better use a good heatsink.

I just would like to comment that if you have an image without HDMI (no fb) and a good heatsink you get slightly better values.

Now is time to move on and learn new platforms...
