Hi All,

       I am trying to use PWM for back-light but after enabling :

Procedure to build eHRPWM driver
                 Device Drivers --->
                        <*> PWM Support --->
                        <*> Davinci eHRPWM support

                Device Drivers --->

                     <*> PWM Support --->
                     <*> eCAP PWM support

after making it as module when I am compiling  kernel I can able to see ehrpwm.o and ecap.0 file so I am confirm files are added as module;

And I have used the same block of code used in board-am335xevm.c ;


But when I am access the /sys/class/pwm/

I didnt find  ecap nor  ehrpwm  ; help anyone i will thankful to you :-

 

Regards

Praveen
