Servo sample for Android Things does not working with i.MX7D

[shangyilim]

Hi!
I ran the pwmservo demo on NXP Pico i.MX7D Developer Kit and it did not work.
I then ran the same demo on Raspberry Pi 3 B and it worked as instructed.

The only difference between both is just the wiring for PWM1 on i.MX7D vs PWM0 on the Raspberry Pi.

I also ranused the PIO CLI to figure out whether the PWM is working or not, and when i ran
pio pwm PWM0 enable 1 --duty=12.5 --freq=50 on my Raspberry Pi 3 B, my servo managed to turn as instructed,
but when I ran pio pwm PWM1 enable 1 --duty=12.5 --freq=50, on the i.MX7D, my servo did not turn.

Any clues?

Thanks!
