Getting Started

Connect your board

If you've just purchased W5500 EVB, follow below steps to start working with your board for the first time.

Connect your board to a PC using USB and connect LAN cable. Don't forget : LAN cable should be connected to the board
The W5500 EVB Need to be LAN cable connected because default demo firmware checks the PHY link status periodically. If the LAN cable is not connected, the board will not operate and RGB LED will not be not blinking.

1. RGB LED blinky

If the board operate normal at the first time, On board RGB LED is blinking forever. The red, green and blue LEDs are blink alternated.

2. On/Off the RGB LED blinky

The RGB LED status will be changed if the button1 (SW1) pressed (LED Blinky On/Off). In this case, the board outputs 'On' or 'Off' message via serial debug port.

3. Serial Debug message print out

The board outputs serial "debug" message via USB port (virtual COM Port). This will give you info about network configuration and loopback socket.
Check the the virtual COM port number in your systems properties.
Please connect with any terminal to that serial port with 115200.8.N.1.

4. Loopback test

The loopback example runs with a TCP session and a UDP session.

First, Board and your PC should have the network config with the same network range.
If you want to modify board-side, edit the following code in [src>>LB_main.c] with the same range which your PC has.

wiz_NetInfo gWIZNETINFO = { .mac = {0x00, 0x08, 0xdc,0x00, 0xab, 0xcd}, //<-mac should be unique.
.ip = {192, 168, 1, 123},
.sn = {255,255,255,0},
.gw = {192, 168, 1, 1},
.dns = {0,0,0,0},
  1. Connect to Board
  2. When connected
    • send data to board
    • check whether the loopback data is same to what it sent before.
  3. When failed to connect
    • Check link status.
    • Check ping test
    • Check network config.
    • Check the security program as virus vaccines and fire-wall on your PC.
  1. Send data
  2. When success
    • check to the loopback data
  3. When fail
    • Check link status.
    • Check ping test
    • Check network config.
    • Check the security program as virus vaccines and fire-wall on your PC.
