Overview

This example works as two USB CDC ACM devices. It will appear as two USB serial devices on PC.

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
  • EVK-MIMXRT1020 board
  • Personal Computer(PC)

Board settings

No special settings are required.

Prepare the Demo

  1. Connect a USB cable between the host PC and the OpenSDA USB port on the target board.
  2. Open a serial terminal with the following settings:
    • 115200 baud rate
    • 8 data bits
    • No parity
    • 1 stop bit
    • No flow control
  3. Compile the demo with the configuration, "flexspi_nor_debug".
  4. Write the program to the flash of the target board.
  5. Press the reset button on your board to start the demo.
  6. Connect a USB cable between the PC and the USB device port of the board.
  7. PC can detect two USB ACM devices. Running the demo ================ When the demo is running, the serial port of the Debug Link will output:

Start USBX device composite example...

Then, connect a USB cable between PC and the USB device port of the board. Two USB serial devices will appear in the Device Manager of Windows. And the serial port will output:

CDC ACM1 device activate CDC ACM2 device activate

ACM1 device serial terminal, press any key, and it will display a string, for example:

fabcdef gabcdef 3abcdef

ACM2 device serial terminal, press any key, and it will display a string, for example:

f123456 g123456 3123456
