Hello Bijoy krishna Sharma ,

Which CAN driver do you used ?

Your project is a demo code or created by yourself?

If you use CodeWarrior IDE,  you can first test create a project with Processor Expert,

there is example for CAN, test whether it can work well on your board.


Have a great day,
TIC

Hello Alice_Yang,

Thanks for your reply. In my Eval. Board (S12ZVM12EVB) i have no CAN Physical driver with the controller but an extra CAN PHY Driver is mounted in the Board. Yes, I used processor expert and the problem is solved.

Anyway thanks for you  advice.....Have a nice day.

BKS
