Tool/software: Linux
Hi,
We have a custom made board, where we have used AM3352 processor and instead of using ECAP0_IN_PWM0_OUT pwm pin we have used EHRPWM0B pin for LCD back light. I am attaching the .dts file for referene that we have used to configure the ehrpwm.
//! Back Light Configuration
backlight {
compatible = "pwm-backlight";
pwms = <&ehrpwm0 0 50000 0>;
brightness-levels = <0 51 53 56 62 75 101 152 255>;
default-brightness-level = <8>;
};
//! Below Is the description the way we have done
ehrpwm0_pins_default: backlightNew_pins {
pinctrl-single,pins = <
0x194 0x1 /* eHRPWM0B_in_PWM0_out.eHRPWM0B_in_PWM0_out MODE1 */
>;
};
ehrpwm0_pins_sleep: ehrpwm0_pins_sleep {
pinctrl-single,pins = <
0x194 (PIN_INPUT_PULLDOWN | MUX_MODE7) /* eCAP0_in_PWM0_out.eCAP0_in_PWM0_out */
>;
};
//! Adding to epwmss0 node
&epwmss0 {
status = "okay";
ecap0: ecap@48300100 {
status = "okay";
pinctrl-names = "default", "sleep";
pinctrl-0 = <&ecap0_pins_default>;
pinctrl-1 = <&ecap0_pins_sleep>;
};
ehrpwm0: ehrpwm@48300200 {
status = "okay";
pinctrl-names = "default", "sleep";
pinctrl-0 = <&ehrpwm0_pins_default>;
pinctrl-1 = <&ehrpwm0_pins_sleep>;
};
};
How ever when we are flashing the .dtb file, the LCD light is not coming up.
Can any one please assist, what is going wrong.
Regards
Sudipta.
