Running a Hello World Program
- When the system is running, start the serial port tool (for example, PuTTY), set the baud rate to 1500000, and connect to the device.
- Enable the serial port, enter the helloworld command in any directory (for example, the root directory of the device) and press Enter. If the message “Hello World!” is displayed, the program runs successfully.
