MCAN Loopback Polling
Introduction
This example demonstrates the CAN message transmission and reception in digital loop back mode with the following configuration.
Classic CAN Message Format.
Message ID Type is Extended, Msg Id 0xD0, 0xD1, 0xD2, 0xD3, 0xD4.
MCAN is configured in Polling Mode.
Arbitration Bit Rate 1Mbps.
Data Bit Rate 5Mbps.
FIFO mode is used for Tx and RX to store message in message RAM.
5 Messages are transmitted and received back internally using internal loopback mode. When all the 5 messages received with the id and the data matches with the transmitted one, then the example is completed.

Steps to Run the Example
When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects).
When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles)
Launch a CCS debug session and run the executable, see CCS Launch, Load and Run
Attention
As the wake-up R5 is the device manager, it needs to be started by the SBL. So it can not be loaded through CCS. It should be flashed and booted through SBL.
Refer Flash a Hello World example for flashing the application.
