wdog01#
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.
Supported Boards#
EVKB-IMXRT1050
Hardware requirements
Mini/micro USB cable
EVKB-IMXRT1050 board
Personal Computer
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.
