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.

Board settings
No special settings are required.
Prepare the Demo
- Connect a USB cable between the host PC and the OpenSDA USB port on the target 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.
- Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
Running the demo
Note: To download binary into hyper flash and boot from hyperflash directly, following steps are needed:
- Select the target flexspi_nor_debug or flexspi_nor_release.
- Compile the project, and get the binaray file "rtwdog.bin"
- Set the SW7: 1 off 2 off 3 off 4 on, then power on the board and connect USB cable to J28
- Drop the binaray into disk "EVK-MIMXRT"
- Wait for the disk disappear and appear again which will take around ~10s, then power off the board
- Set the SW7: 1 off 2 on 3 on 4 off, then power on the board
- After power on the baord, program has already started to run, reset SW4 is recommended.
Note: To debug in hyper flash in MDK, following steps are needed:
- Select the target flexspi_nor_debug or flexspi_nor_release.
- Compile the project.
- Press F8 or click the download button, to program the application into hyper flash.
- Set the SW7: 1 off 2 on 3 on 4 off, then power on the board
- Push SW4 to reset.
- Start to debug.
These instructions are displayed/shown on the terminal window:
