MCUXpresso SDK Documentation

wdog32#

Overview#

The WDOG32 Example project is to demonstrate usage of the KSDK wdog32 driver. In this example, fast testing is first implemented to test the wdog32. After this, refreshing the watchdog in None-window mode and window mode is executed. Note wdog32 is disabled in SystemInit function which means wdog32 is disabled after chip emerges from reset.

Running the demo#

When the example runs successfully, you can see the similar information from the terminal as below.

Prepare the Demo

This should be run together with uboot.

  1. Build the project and generate the .bin file.

  2. Copy the .bin file to <sdk_dir>/tools/imgutil/evkmcimx7ulp folder and rename to sdk20-app.bin.

  3. In the folder <sdk_dir>/tools/imgutil/evkmcimx7ulp, run “mkimage.sh ram or mkimage.sh flash” (see readme in the <sdk_dir>/tools/imgutil )to create bootable image.

  4. Prepare an SD card with the prebuilt U-Boot image and copy the sdk20-app.img generated into the SD card. Then, insert the SD card to the target board. Make sure to use the default boot SD slot and check the dip switch configuration

  5. Open a serial terminal with the following settings to connect to Cortex-A:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  6. Connect 5V power supply to the board, switch SW1 to power on the board.

  7. Hit any key to stop autoboot in the terminals, then enter to U-Boot command line mode. Then write the image and run it from QSPI Flash with the following commands:

    • sf probe

    • sf erase 0x0 0x20000

    • fatload mmc 0:1 0x62000000 sdk20-app.img

    • sf write 0x62000000 0x0 0x20000

  8. Open a serial terminal with the following settings to connect to Cortex-M:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  9. Switch the SW1 to re-power the board.

  10. Hit any key to stop uboot autoboot in the Cortex-A terminals.
