Part Number: AM3352

SDK6, I know it is pretty old.

In customer use case, when use Timer 4 PWM mode and PWM 1, PWM2 together, will result in abnormal as below.

If only use Timer 4 PWM or PWM1/2, it is OK.

Please help have a look. anymore information needed, please let me know.

Hello Tony,

Unfortunately, AM335x SDK6 is too old for me to support the software. I might not be able to offer any help here. I do not think the current PWM driver documentation would apply to your SDK release. Try this wiki documentation from 2012: AM335x PWM Driver's Guide.

When you say PWM1/2, are you talking about ePWM or eCAP?

Does it work if you use both PWM1 and PWM2 at the same time? Or does that also cause problems?

Regards,

Nick
