Overview

The MMCCARD FreeRTOS project is a demonstration program that uses the SDK software. It reads/writes /erases the MMC card continusly. The purpose of this example is to show how to use MMCCARD driver with FreeRTOS in SDK software to access MMC card.

Note: User can use MMC plus card or emmc(on board IC, but not recommand use emmc socket,due to high speed timing restriction)

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
  • SD to Micro SD coverter
  • MMC card

Board settings

Please insert the MMC card into card slot(J15)

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 MMC 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:

MMCCARD freertos example.

Read/write the card continuously until encounter error......

Write/read one data block......
Compare the read/write content......
The read/write content is consistent.
Write/read multiple data blocks......
Compare the read/write content......
The read/write content is consistent.
Erase data groups......

Input 'q' to quit read/write/erase process.
Input other char to read/write/erase data blocks again.

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.
