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.

SDK version

  • Version: 2.15.000

Toolchain supported

  • IAR embedded Workbench 9.40.1
  • GCC ARM Embedded 12.2
  • Keil MDK 5.38.1
  • MCUXpresso 11.8.0

Hardware requirements

  • Mini/micro USB cable
  • EVK-MIMXRT1020 board
  • Personal Computer

Board settings

No special settings are required.

Prepare the Demo

  1. Connect a USB cable between the host PC and the OpenSDA USB port on the target board.
  2. Open a serial terminal with the following settings:
    • 115200 baud rate
    • 8 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.

Note: To debug in qspiflash, following steps are needed:

  1. Select the flash target and compile.
  2. Set the SW8: 1 off 2 off 3 on 4 off, then power on the board and connect USB cable to J23.
  3. 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.
