CAN FD bit rate

alagappan muthiah

Hello Techies,

I am working in CAN FD. I am trying with 500kbps/2Mbps Nominal(arbitration) and data bitrate.

When i am choosing Nominal sampling point : 80 , Data sampling point : 70 Nominal sampling point : 70 , Data sampling point : 65
CAN FD transmission is working.

But when i am choosing same sampling point for both nominal and data bits, then it is not working.
For example Nominal sampling point : 80 , Data sampling point : 80 Nominal sampling point : 70 , Data sampling point : 70

For these settings CAN FD transmission is not working.

Is that anything is not proper in my settings or Is there any logic behind this selection of sample point between
nominal and data fields.

Thanks

Alagappan
