Hi,
I am working on AM1808 processor, I have designed my LCD back-light with the below pin mux configuration.
I have configured ECAP2 & EPWM0 (#define PWM_DEVICE_ID "ehrpwm.0" && #define PWM_DEVICE_ID "ecap.2")
two configuration, but it is not working. This ECAP2 & EPWM0 pin we are controlling with LCD backlight. But at the boot time
I need the uboot configuration and also where I need to configure it in kernel. Please find my LCD pwm driving circuit
Please need your suggestions to enable the LCD backlight using pwm or ecap..
Thanks,
Francis
