CAN FD configuration settings

psarkar — Wed, 29 Nov 2023 02:10:31 GMT

I am trying to run send CAN FD frames using S32K344 + TJA1145A, and receive using PCAN View, I do receive 8 byte frames but not when I change it to 64 bytes.

Any guidance on what and how to configure it for 500kbps arbitration and 2Mbps CAN baudrate, would be really helpful. My PCAN View and NXP FlexCAN baudrate settings are as follows:

Please let me know if any other information is required

Thank you!

Hi@psarkar

If you are using our EVB, you can test this demo.

Although we are using different PCAN tools, based on your current configuration, i think you should be able to receive data from EVB.
