Overview#

NAND flash management demo shows file system management on an external NAND flash device over an SPI interface using the DHARA flash translation layer, the FatFs file system, and FreeRTOS, driven by interactive shell commands.

Supported Boards#

Hardware requirements

  • USB cable

  • FRDM-IMXRT700 board

  • Personal Computer

Board settings

Remove SJ425, SJ426, SJ427, SJ428, SJ429 and populate SJ420, SJ421, SJ422, SJ423, SJ424.

XSPI1 NAND pin assignment:

NAND Pin   RT700 Signal   PIO
/CS        XSPI1_SS0_N    PIO5_0
CLK        XSPI1_SCLK0    PIO5_10

Prepare the Demo

  1. Connect a USB cable between the host PC and the MCU-Link 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

When the demo runs successfully, the log would be seen on the terminal like below. After the shell is available, start with command “help”.
