Hardware requirements

• Micro USB cable

• MIMX8ULP-EVK/EVK9 board

• J-Link Debug Probe

• 5V power supply

• Personal Computer

Board settings

No special settings are required.

Prepare the Demo

1. Connect 5V power supply and J-Link Debug Probe to the board, switch SW10 to power on the board.

2. Connect a micro USB cable between the host PC and the J17 USB port on the cpu 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. Launch the debugger in your IDE to begin running the example.
