Overview

The flexcan_loopback_functional example shows how to use the loopback test mode to debug your CAN Bus design:

To demonstrates this example, only one board is needed. The example will config one FlexCAN Message Buffer to Rx Message Buffer and the other FlexCAN Message Buffer to Tx Message Buffer with same ID. After that, the example will send a CAN Message from the Tx Message Buffer to the Rx Message Buffer throuth internal loopback interconnect and print out the Message payload to terminal.

SDK version

  • Version: 2.15.000

Toolchain supported

  • IAR embedded Workbench 9.40.1
  • Keil MDK 5.38.1
  • GCC ARM Embedded 12.2
  • MCUXpresso 11.8.0

Hardware requirements

  • Mini/micro USB cable
  • EVKB-IMXRT1050 board
  • Personal Computer

Board settings

No special settings are required.

Prepare the Demo

  1. Connect a USB cable between the PC host and the OpenSDA USB on the board.
  2. Open a serial terminal on PC for OpenSDA serial device with these settings:
    • 115200 baud rate
    • 8 data bits
    • No parity
    • One stop bit
    • No flow control
  3. Download the program to the target board.
  4. Either press the reset button on your board or launch the debugger in your IDE to begin running the example.

Running the demo

Consider special errata 005829 feature, the 1st valid MB should be used as reserved one. The TX MB number will change from 8 to 9, while RX MB number will change from 9 to 10 When the example runs successfully, following information can be seen on the OpenSDA terminal:


==FlexCAN loopback functional example -- Start.==


Send message from MB9 to MB10

tx word0 = 0x11223344

tx word1 = 0x55667788


Receved message from MB10

rx word0 = 0x11223344

rx word1 = 0x55667788


==FlexCAN loopback functional example -- Finish.==
