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

Hi Alagappan,
how do you detect if it is working or not, do you have CAN analyzer or do you have another device and look if it received anything?

Yes i Have tool like CAN Analyzer. With that i sent messages and able to see the messages in receive interrupt of my device ISR handler
Which analyzer exactly do you have?
I have seen with www.peak-system.com/PCAN-USB-FD.365.0.html analyzer that I had to add bitrates and use same frequency and segment setting as were set on target and then it worked fine, otherwise if I used same bitrate but not same segment settings and CAN clock frequency it was not working.
