On evaluation board BCM943362WCD4 wiced_pwm_start() and wiced_pwm_stop() used for the onboard LEDs, dont seem to have any effect. Unlike specified in the API documentation, with this board the function wiced_pwm_init() starts the PWM.
I have looked in to the application you have told.
But When i use simple functions .
USING BCM943362WCD4 EVAL board with WICED SDK 3.1.2
wiced_pwm_init(WICED_PWM_1, 24000 , 50.00 );
The starts at given frequency and duty cycle but its not stopping.
