Tool/software:

Hello,

I am using MSPM0G3507 with TCAN3413 CAN transceiver on custom board. Configured it as per datasheet.

The CAN communication is working is i set 50kpbs in Sysconfig file in MCAN. But didn't work for 500Kbps. It gives Error passive warning.

Please guide me on the same.

Regards,

Nitin

Hi, can you share more about your settings in sysconfig and the error output?

I am not familiar with the4 particular CAN interface you are using, what is the maximum rate for that device?

Ok, so the only thing you are changing is the bitrate correct? I don't have a TCAN EVM to duplicate the issue, but can you connect a logic analyzer to the pins and see if we can narrow down where the issue lies?
