I noticed PWM3 and PWM2 is interference each oher.

I explain what I found as follows

.Use PWM3(P13) and PWM(P14), then set them to output enable mode

.PWM3 doesn't work

.GPIO:P28(connected to PWM2) enable

.PWM3 works but overlap PWM2 wave on PWM3

How can I solve this problem, are there any settings about it?

Sorry we don't have the users code.

Please take a look at the PWM Tones Code here:

Take a look at this thread created by hsontag@sontagtech.com, he was able to get P14/P13 working by configuring them after calling pwm_start: Re: How to get all 4 PWMs working at the same time on BCM20736S

This thread also provides some code that shows all 4 PWMs working together, which was something early on we thought was not possible with the SIP module (only the SoC): Re: How many PWM channels available in BCM20732S  ?

sbs, janusw and stuart_sf all tested this out and it works.

Could you send reproducible code to me directly?
