Add to /boot/uEnv.txt
#cape_enable=capemgr.enable_partno= optargs=capemgr.enable_partno=am33xx_pwm,bone_pwm_P9_16,bone_pwm_P9_22,bone_pwm_P9_21,bone_pwm_P8_19,bone_pwm_P8_13,bone_pwm_P9_14
This will enable PWM control on leds
Controlling LEDs
List of LED controls
P9.14 Red 1
P9.16 Green 1
P9.22 Blue 1
P8.13 Red 2
P9.21 Blue 2
P8.19 Green 2
From shell
500000 is a PWM period
Set 50% duty (500000 / 2 = 250000)
