STM32F429 outputs complementary PWM but the waves rise and drop lowly (above 10us)

I'm doing motor drive project and its six pwm signals output from F429 connect with drive IC-- DRV8302 directly, but pwm rises and drops lowly (above 10us) as attached picture. I think this rising time takes too long,is right?

Thank you.

Check the relevant pins' "drive" setting in respective GPIO_OSPEEDR.
