Hardware requirements

  • Micro USB cable

  • EVK-MIMXRT595 board

  • Personal Computer

  • SD card

Board settings

Make sure resistors R691~R697 are populated and resistors R611~R620,R660, R661 are removed.

Prepare the Demo

  1. Connect a micro USB cable between the PC host and the CMSIS DAP USB port (J40) on the 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. Launch the debugger in your IDE to begin running the demo. Please insert the SDCARD into card slot(J32)

Running the demo

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

SDCARD polling example.

Please insert a card into board.

After the SDCARD inserted into J32, the log like below would be seen:

Card size xxxxx bytes

Working condition:

  Voltage : xxxV

  Timing mode: xxx

  Freq : xxx HZ

Read/Write/Erase 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 multiple data blocks......

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