NUCLEO-F429Zi 2 CAN Bus communicating with each other

[bhong.1]

Hello

Using CAN1 and CAN2 Bus on the ST Nucleo-F429Zi board, messages sent from CAN1 can be received from CAN2 and messages sent from CAN2 can be received from CAN1.

I want to write a program. Software Tool uses STM32CubeIDE and tries to communicate with two CAN Bus without CAN Driver Board.

As a result of the test, Loop Back Mode of CAN1 BUS works well. However, if a message is sent from CAN1 Bus to CAN2 BUS, the interruption of CAN2 BUS does not occur.

Of course, CAN2 RX0 Interrupt is enabled in CubeMX.

Thank you
