After reading lots of stuff I have what I thought might work. Segments from my .dts
exclusive-use = "p9.25"; /* R30[7] */ fragment@0 { target = <&am33xx_pinmux>; __overlay__ { mygpio: pinmux_mygpio{ pinctrl-single,pins = < 0x1AC 0x25 /* P9.25 mode 5 pulldown output */ >; }; }; }; If I do nothing in my pru code this pin is always high even after I reboot the bbb. I tried CLR R30.T7 and the pin still remained high. Is there something else I need to do.
