The questions about using PWM. FireprimeS+(RK3128)

james

Fireprime S+ on board

If you check it with the adb shell as shown below, / sys / kernel / class / PWM will not come up here.

What is the problem?

Try to use both PWM0, PWM1, PWM2, and PWM3.

​Reference website : http://wiki.t-firefly.com/index.php/FirePrime/PWM/en
kernel / arch / arm / boot / dts / rk3128-fireprime.dts:

I added this.

​& Pwm0 {
                Status = "okay";
        };
& Pwm1 {
                Status = "okay";
        };
& Pwm2 {
                Status = "okay";
        };
& Pwm3 {
                Status = "okay";
        };

Please make sure you have another file to edit.
