Hello, my name is Pavel, and I will be supporting your case, I reviewed your question, but this is not enough clear, "PWM driver is not found in the toolchain".
If you are using the MCUXpresso need to select all the libraires and the toolchain.
Then when you have installed on the IDE you could import some examples from that like this.
Best regards,
Pavel
Hello, the next information could help you.
I opened a blnky_led example where there is not any a PWM, so I select the MCUXpresso Configuration then on the pop-up window and type PWM.
Let me know if the information is not helpful maybe I do not understand.
Best regards,
Pavel
