Hardware requirements

Micro USB cable
MCIMX7ULP-EVK board
J-Link Debug Probe
5V power supply
Personal Computer

Board settings

No special settings are required.

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

Please note that this application must be built with flash link file! Build with RAM link file might fail due to shortage of RAM size.

Prepare the Demo

Connect 5V power supply and J-Link Debug Probe to the board, switch SW1 to power on the board.
Connect a micro USB cable between the host PC and the J6 USB port on the target board.
Open a serial terminal with the following settings:
- 115200 baud rate
- 8 data bits
- No parity
- One stop bit
- No flow control
Download the program to the target board.
Either press the reset button on your board or launch the debugger in your IDE to begin running the example.
