Hardware requirements

• Mini/micro USB cable

• MCX-N9XX-EVK board

• Personal Computer

• USB to TTL converter

Board settings

Connect the USB to TTL converter to MCX-N9XX-EVK board. MCX-N9XX-EVK UART pins:

• TX of USB2COM to J20-9(P0_12)

• RX of USB2COM to J20-12(P0_13)

Prepare the Demo

Note: MCUXpresso IDE project default debug console is semihost

1. Connect a micro USB cable between the PC host and the MCU-Link USB port (J5) on the board

2. Open a serial terminal with the following settings:

   • 115200 baud rate

   • 7 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 demo.

Running the demo

When the demo runs successfully, the log would be seen on the MCU-Link terminal like:
