i can see the 2 pwm are added pwm1:0 , pwm1: 1

using cd pwm1:0  i am assigning the duty cycle , period and enable

if i rebooted the BBB means this configurations are erasing, why i am not 
getting??

using config-pin -l  P9.14 
         config-pin P9.14 pwm 

i am setting pin for pwm as p9.14

in hardware wise i am connecting 1 external led providing 1 connection from 
P9.14 and other end to ground.

but led should glow based on pwm duty-cycle, but here the LED not all 
glowing ???

please suggest me where i am missing??
