Overview

The Hello World demo application provides a sanity check for the new SDK build environments and board bring up. The Hello World demo prints the "Hello World" string to the terminal using the SDK UART drivers. The purpose of this demo is to show how to use the UART, and to provide a simple project for debugging and further development. Note: Please input one character at a time. If you input too many characters each time, the receiver may overflow because the low level UART uses simple polling way for receiving. If you want to try inputting many characters each time, just define DEBUG_CONSOLE_TRANSFER_NON_BLOCKING in your project to use the advanced debug console utility.

SDK version

  • Version: 2.15.000

Toolchain supported

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

Running the demo

The log below shows the output of the hello world demo in the terminal window:

hello world.

Note: To download binary into qspiflash and boot from qspiflash directly, following steps are needed:

  1. Compile flash target of the project, and get the binaray file "hello_world.bin".
  2. Set the SW8: 1 off 2 off 3 on 4 off, then power on the board and connect USB cable to J23.
  3. Drop the binaray into disk "RT1020-EVK" on PC.
  4. Wait for the disk disappear and appear again which will take couple of seconds.
  5. Reset the board by pressing SW3 or power off and on the board.

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.
