Overview
The Hello World project is a simple demonstration program that uses the SDK UART drivere in combination with FreeRTOS. The purpose of this demo is to show how to use the debug console and to provide a simple project for debugging and further development.
The example application creates one task called hello_task. This task print "Hello world." message via debug console utility and suspend itself.

Prepare the Demo
- Connect a USB cable between the host PC and the OpenSDA 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 demo.
Note: To debug in qspiflash, following steps are needed:
- Select the flash target and compile.
- Set the SW8: 1 off 2 off 3 on 4 off, then power on the board and connect USB cable to J23.
- Start debugging in IDE.
- Keil: Click "Download (F8)" to program the image to qspiflash first then clicking "Start/Stop Debug Session (Ctrl+F5)" to start debugging. Running the demo ================ After the board is flashed the Tera Term will print "Hello world" message on terminal.
Example output: Hello world.
