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.
