Hardware requirements

  • Type-C USB cable

  • IMX95VERDIN-EVK board

  • J-Link Debug Probe

  • 12V~20V power supply

  • Personal Computer

Board settings

The example requires connecting the FLEXIO1 pins with the USB2COM pins The connection should be set as follows:

  • FLEXIO_RX(J34-1) on base board, TX of USB2COM connected

  • FLEXIO_TX(J45-4) on base board, RX of USB2COM connected

  • GND (J26-2) on base board, Ground of USB2COM connected

Please note this application can’t support running with Linux BSP!

Note

Please run the application in Low Power boot mode (without Linux BSP). The IP module resource of the application is also used by Linux BSP. Or, run with Single Boot mode by changing Linux BSP to avoid resource conflict. Tips: After you insert the USB2COM, a new USBCOM will be found. The function output in new USBCOM.

Prepare the Demo

  1. Connect 12V~20V power supply and J-Link Debug Probe to the board, switch S6 to power on the board.

  2. Connect a Type-C USB cable between the host PC and the J4 USB port on the target board.

  3. Open a serial terminal with the following settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  4. Download the program to the target board.

  5. Either re-power up your board or launch the debugger in your IDE to begin running the example.

Running the demo

When the example runs successfully, you can see the similar information from the terminal as below.
