    The board ran for months, but someday the codes in flash disappeared, and the board died.
    How and Where I can figure out the key problem?

    Yes, the reset pin can help this issue. Or restart the power of the device can also reset the W5500. But this issue will happen in a few minute again.

    I used wiznet 5500 for tcp connection, but sometime I didn't know why it stopped. And then I tried to reset system, but the socket not avaiable still exiested. I had to power off the board then the wiznet work fined agnin.

    How to reset WIZnet 5500 while socket is not available?

    No free sockets found

    This is my code, and run on the board STM32F4DISCOVERY

    let WIZnet = require("WIZnet");
let st = require("Storage");
let WebServer = require('WebServer');
let ip = "192.168.1.238";
let gateway = "192.168.1.1";
let eth = null;


E.on('init', function () {
    SPI2.setup({mosi: B15, miso: B14, sck: B13});
    eth = WIZnet.connect(SPI2, B12);
    setTimeout(function () {
        eth.setIP({ip: ip, gateway: gateway, subnet: "255.255.255.0",dns:"8.8.8.8"});
        console.log("ip", eth.getIP());
        startServer();
    }, 1500);
});

function startServer() {
    var webs = new WebServer({
        port: 8080,
        file_system: '/var/www/',
        memory: {

  • How to keep a continuous web access while using require("http").createServer

    Avatar for user109783

    When I first time visited the device like this, http://192.168.1.111
    Ok,no matter how I pressed the F5 button for refreshing, the connection was ok.
    But when I write a new website like: http://www.google.com and then press the back history for visiting the http://192.168.1.111 again, it failed, the browser rejected for visiting, maybe the device did.

    The page I load is very simple and little cotent, I just press the F5 for refreshing the website, but somehow the server reject for connecting.

    And I invoked WIZnet.getStatus(), it was still working.

    {
  state: "online",
  id: "W5500",
  phylink: "up",
  phypowmode: "normal",
  by: 0, mode: 1, speed: 100, duplex: 0 }

    But when I visit website by http://ip , the browser reject like this: ERR_CONNECTION_REFUSED

    function pageRequest(req, res) {
  res.writeHead(200);
  res.end("Hello World");
}
require("http").createServer(pageRequest­).listen(8080); // port 8080

    The code like this, when the borad work, it's ok for visiting the pages which the server supply at the very first time. But when I jump for the other websites and visit back via return history of browser, the server stop. I can't visit the server website again. I have to invoke load() for restart then I access the server again.

    How to Keep web server working for long time?
