Hi Vimal:

There is a flexcan_interrupt example shows how to use Flexcan driver with 2 boards.

SDK_2.5.0_TWR-K64F120M\boards\twrk64f120m\driver_examples\flexcan\interrupt_transfer

In this example, 2 boards are connected through CAN bus. Endpoint A(board A) send a CAN Message to
Endpoint B(board B) when user press space key in terminal. Endpoint B receive the message, print
the message content to terminal and echo back the message. Endpoint A will increase the received
message and waiting for the next transmission of the user initiated.
