Our ADAS Controller is based on Renesas RH850/U2A16 Microcontrollers. We are using Infineon TLE9255WSK Partial Network CAN Transceivers. We are using Vector CANoe Professional.

When a CAN message is transmitted on CAN Channel 2 from our controller to Vector CANoe, there is Bit Stuffing Error. Please see attached filename Bit_Stuffing_error_CAN_Trace.PNG.

Also, attached are files that show our Vector CANoe tool configuration.

We are using 120 Ohms termination resistor.

What might be the problem? Is the problem in Vector CANoe Tool configuration? Or is this problem in CAN Driver source code in our controller?

The problem occurs with Two specific standard CAN Ids. One is transmitted on CAN 1 to Vector CANoe tool and the other is transmitted on CAN 2 by Vector CANoe tool.

Typo on above comment:

Why multiple senders on the wire might cause this problem?

How to debug that sender is causing this problem?
