Getting Started with the W6100-EVB

Check the board

**If you have just purchased W6100-EVB, follow the procedure presented below: **
Connect your board to a PC using USB and connect LAN cable. USB is Micro B USB type. W6100-EVB doesn't care uses Micro USB B type or DC-JACK(DC-5V) Don't forget: It must be supplied DC-5V
The W6100-EVB can use be Micro USB B type or DC-JACK to the power supply. Users can chooseone of these options.

LAN Connector
When users did connect to LAN cable, users should be check RJ-45(ethernet connector) LEDs. There are two indicator LEDs in RJ-45. Orange LED indicates 100M ACT. Green LED indicates LINK.

Hello World

This section is descriptive to W6100-EVB operation. let the following points for the board operation. W6100-EVB supported to eclipse loopback example code. Make new W6100-EVB Project is clicking on this link. If you want to know "How to download the program" click on this link.

1. Serial Debug message print out

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

4. Loopback test

If you need detailed figures, please refer to the below link.
TCP and UDP 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. If you want to modify your PC-side, refer to IP configuration.

wiz_NetInfo gWIZNETINFO = { .mac = {0x00,0x08,0xdc,0x57,0x57,0x20},
.ip = {192,168,11,16},
.sn = {255, 255, 255, 0},
.gw = {192, 168, 11, 1},
.dns = {8, 8, 8, 8},
.lla = {0xfe,0x80, 0x00,0x00,
0x00,0x00, 0x00,0x00,
0x02,0x08, 0xdc,0xff,
0xfe,0x57, 0x57,0x61},
0x00,0x00,0x00, 0x00,
.gw6={0xfe, 0x80, 0x00,0x00,
0x02,0x00, 0x87,0xff,
0xfe,0x08, 0x4c,0x81},

  • Port 5000 : IPv6
  • Port 5001 : IPv4
  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.

How to upload firmware

Flash programming via UART

1. How to use W6100-EVB ISP mode

Press the 'Boot0' push button switch on board until turn on the board after reset or power supply.

2. Run the STMicroelectronics Flash loader demonstrator

STMicroelectronics Flash loader demonstrator is a program to perform in-system programming (ISP) of the MCU flash via its UART.
🌎'ST Flash lodaer demonstrator' download page

3. Tool settings

Set the settings on main window of Flash loader demonstrator program. It is easy to set along with each step.
The figure below shows the default configuration for W6100-EVB.

4. Click to 'Next' button

refer to below pictures If you do not go to the next page in flash loader demonstrator, users try again this action. 'Press the 'Boot0' push button switch on board until turn on the board after reset or power supply.'

5. Run the new program

After finish to flash programming and board reset, The MCU will be running the program
When running to loopback program, ie as below picture serial debug message print out.
