Dear all,
Does anyone know of problems using the quadrature detector on BBB
*3.8.13-bone70* ? It working fine on a BBB with *3.8.13-bone47*. I'm using
the same overlay file for both BBB versions. My test program does not show
any counted pulses when using *bone70*. *bone47 *works fine. The overlay
file (before compilation) looks as follows:
/*
* Enable eQEP2 on the Beaglebone White and Black
*/
/dts-v1/;
/plugin/;
/ {
compatible = "ti,beaglebone", "ti,beaglebone-black";
/* identification */
part-number = "bone_eqep2";
version = "00A0";
fragment@0 {
target = <&am33xx_pinmux>;
__overlay__ {
pinctrl_eqep2: pinctrl_eqep2_pins {
pinctrl-single,pins = <
0x030 0x34 /* P8_12 = GPIO2_10 = EQEP2A_in, MODE4 */
0x034 0x34 /* P8_11 = GPIO2_11 = EQEP2B_in, MODE4 */
>;
};
};
};
fragment@1 {
target = <&epwmss2>;
__overlay__ {
status = "okay";
};
};
fragment@2 {
target = <&ocp>;
__overlay__ {
eqep2_helper {
compatible = "bone-pinmux-helper";
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_eqep2>;
status = "okay";
};
};
};
};
