For EMI/C problems, change the crystal value from 40M ->16M(include HW&SW) in S32K116.

The cyrstal vibration is OK after the hardware test and modification.

I change SOSC to 16M and check Configuration compare as below:

Check can communication through the tool,found no data ,and the LED light is not on ,as blow.

Is there something I should configure or something I didn't configure?

Hi@jingfang

It should be incorrectly configured, try this CAN configuration,

Is your PE's clock 4MHz?
