| Overview |
| ======== |
| The WDOG Example project is to demonstrate usage of the KSDK wdog driver. |
| In this example,implemented to test the wdog. |
| Please notice that because WDOG control registers are write-once only. And |
| for the field WDT, once software performs a write "1" operation to this bit, |
| it can not be reset/cleared until the next POR, this bit does not get reset/ |
| cleared due to any system reset. So the WDOG_Init function can be called |
| only once after power reset when WDT set, and the WDOG_Disable function can |
| be called only once after reset. |
| |

| Prepare the Demo |
| ================ |
| 1. Connect 12V power supply and J-Link Debug Probe to the board, switch SW701 to power on the board |
| 2. Connect a USB cable between the host PC and the J1701 USB port on the target board. |
| 3. Open a serial terminal with the following settings: |
| - 115200 baud rate |
| - 8 data bits |
| - No parity |
| - One stop bit |
| - No flow control |
| 4. Download the program to the target board. |
| 5. Launch the debugger in your IDE to begin running the demo. |
| |
| Running the demo |
| ================ |
| The log below shows the output of this demo in the terminal window: |
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| |
| ******** System Start ******** |
| System reset by: Power On Reset! |
