Overview

The OCOTP example project is a demonstration program that uses the KSDK software to access eFuse map. Consider of the feature of One-Time programable, this example will just print the version of OCOTP controller.

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

Board settings

No special settings are required.

Prepare the Demo

  1. Connect a USB cable between the host PC and the OpenSDA 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

The log below shows the output of the ocotp example in the terminal window:

OCOTP Peripheral Driver Example

OCOTP controller version: 0x06000000

Note: To download binary into qspiflash and boot from qspiflash directly, following steps are needed:

  1. Compile flash target of the project, and get the binaray file "ocotp_example.bin".
  2. Set the SW8: 1 off 2 off 3 on 4 off, then power on the board and connect USB cable to J23.
  3. Drop the binaray into disk "RT1020-EVK" on PC.
  4. Wait for the disk disappear and appear again which will take couple of seconds.
  5. Reset the board by pressing SW3 or power off and on the board.

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.
