Hardware requirements

Micro USB cable
EVK-MIMXRT595 REV C1 board
Personal Computer

Board settings

Make sure resistors R691~R697 are removed and resistors R611~R620,R660,R661,R698 are populated.

Prepare the Demo

Connect a micro USB cable between the PC host and the CMSIS DAP USB port (J40) on the board
Open a serial terminal with the following settings:
- 115200 baud rate
- 8 data bits
- No parity
- One stop bit
- No flow control
Download the program to the target board.
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:

MMCCARD interrupt example.

Card user partition size xxxxx bytes

Working condition:

  Voltage: xxxxxx

  Timing mode: xxx

  Bus width: xxxx

  Freq : xxxxx HZ

Read/write the user partition 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.
