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.

Supported Combinations

Parameter	Value
CPU + OS	m4fss0-0 freertos
	m4fss0-0 nortos
	r5fss0-0 freertos
Toolchain	ti-arm-clang
Board	am62x-sk, am62x-sk-lp, am62x-sip-sk
Example folder	examples/drivers/mcan/mcan_loopback_polling

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 an example application for flashing the application.
