Incorrect baudrate CAN Network example project on STM32F769I-EVAL?

I'm trying to run the CAN Network example (\STM32Cube_FW_F7_V1.4.0\Projects\STM32F769I_EVAL\Examples\CAN\CAN_Networking\MDK-ARM).
EVAL board Jumpers are set according to the documentation, I'm running the example without any changes.

I have one EVAL board connected to a USB CAN-USB monitor (PEAK PCAN-USB). After I hit the tamper button in order to send a CAN message, the CAN monitor gives a BUSHEAVY error. Very often BUSHEAVY is caused by bit timing issues. 

This example based on EVAL units running in the same CAN network. Maybe it’s never tested with an external CAN USB tool, to be sure the bitrate is really according specifications?


Anybody familier with this issue?
