Overview

The SDCARD FatFs FreeRTOS project is a demonstration program that uses the SDK software. It reads/writes /erases the SD card continuously. The purpose of this example is to show how to use SDCARD driver with FatFs and freeRTOS in SDK software to access SD card. Note: The output log of the case is not constant, since difference of card access speed and platform will affect the behavior of card access task.

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
  • EVKM-IMXRT1020 board
  • Personal Computer
  • SD card

Board settings

Please insert the SDCARD into card slot(J20) Note: If you want to use a SD3.0 card with SD3.0 protocol, just insert a SD3.0 card into the card slot will be ok.

Prepare the Demo

  1. Connect a micro USB cable between the PC host and the OpenSDA USB port on the board.
  2. Open a serial terminal on PC for OpenSDA serial device with these settings:
    • 115200 baud rate
    • 8 data bits
    • No parity
    • One stop bit
    • No flow control
  3. Insert SD card to card slot
  4. Download the program to the target board.
  5. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.

Running the demo

When the demo runs successfully, the log would be seen on the terminal like:
