COP Example

Overview

The COP Example project is a demonstration program that uses the KSDK software to enable Watchdog and continuously refreshes the Watchdog to prevent the CPU reset. After pushing the software button, the Watchdog expires after approximately 1 seconds and the chip is reset.

Supported Platforms

These Freescale Freedom development platforms and Tower System modules are supported by the COP example.

Getting Started

Hardware settings

The COP Example project does not call for any special hardware configurations. Although not required, the recommendation is to leave the development board's jumper settings and configurations in default state when running this example.

Prepare the example

  1. Connect a USB cable between the PC host and the OpenSDA USB port on the board.
  2. Open a serial terminal with these 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 example.

Run the example

These instructions are displayed/shown on the terminal window:
