If the light on the Jaguar is flashing, you are not receiving any sort of control signal from the digital side car. This can be a result of not opening the jag correctly in your code, having a bad PWM connection, having the PWM plugged in backwards, or having a bad cable between the digital side car and the cRio.

You will need to verify all of these. You can confirm that you have a good PWM cable using a multimeter.

You did not show your code opening the PWM, so I do not know if that code is ok. The only way I know of to check the ribbon cable is to get another known 'good' cable and swap it out. I'd check the PWM and your code before anything else.
