Overview

The lwip_ping demo application demonstrates a Ping Demo on the lwIP TCP/IP stack which using the ICMP protocol. The application periodically sends the ICMP echo request to a PC and processes the PC reply. Type the "ping $board_address" in the PC command window to send an ICMP echo request to the board. The lwIP stack sends the ICMP echo reply back to the PC.

SDK version

  • Version: 2.15.000

Toolchain supported

  • IAR embedded Workbench 9.40.1
  • Keil MDK 5.38.1
  • GCC ARM Embedded 12.2
  • MCUXpresso 11.8.0

Hardware requirements

  • Mini/micro USB cable
  • Network cable RJ45 standard
  • EVK-MIMXRT1020 board
  • Personal Computer

Board settings

No special settings are required.

Note: To debug in qspiflash, following steps are needed:

  1. Select the flash target and compile.
  2. Set the SW8: 1 off 2 off 3 on 4 off, then power on the board and connect USB cable to J23.
  3. Start debugging in IDE.
    • Keil: Click "Download (F8)" to program the image to qspiflash first then clicking "Start/Stop Debug Session (Ctrl+F5)" to start debugging. Prepare the Demo ================
  4. Connect a USB cable between the PC host and the OpenSDA(or USB to Serial) USB port on the target board.
  5. Open a serial terminal on PC for OpenSDA serial(or USB to Serial) device with these settings:
    • 115200 baud rate
    • 8 data bits
    • No parity
    • One stop bit
    • No flow control
  6. Insert the Ethernet Cable into the target board's RJ45 port and connect it to your PC network adapter.
  7. Configure the host PC IP address to 192.168.0.100.
  8. Open a web browser.
  9. Download the program to the target board.
  10. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.

Running the demo

When the demo runs, the log would be seen on the terminal like: Initializing PHY...
