Good morning all
I am trying to output allwinner A20 clk_out_a to the relevant PI12 of the
cpu
That should be possible in theory and olimex board actually has a pin where
I can test it.
My current setup is uBoot bootloader that can successfully boot Linux
version 4.3.0-rc1-96427-g904c778-dirty
I am using the sun7i-a20-olinuxino-micro.dts where I have removed the uart6
(that should be conflicting with clk_out_a) and I have added
&clk_out_a {
pinctrl-names = "default";
pinctrl-0 = <&clk_out_a_pins_a>;
status = "okay";
};
in the dts file, compiled and installed
Now, there is nothing whatsoever in the relevant pin and the question is
What am I missing ?
Thanks for any hints you may give me
P.S. Yes, I have read quite a lot documentation on dts, but evidently not
enough to find the solution myself.
