    Merry Christmas all. I've been having this issue off and on with the last couple of builds.
    I notice several issues. Using ESPtool, and the erases function I see this may take some time but immediately the erase completes without a report of areas erased?
    When I program 1.84 - 1.87, I get watchdog restarts. 1.89 seems to run properly. 1.90 resets continually. I am running this on a NodeMCU v3 module. It should also be noted that after flashing 1.9, I cannot use esptool to flash. Fortunately, the Arduino IDE is able to recover from this. Hope this helps. Regards, Jim

    And just like that it's working. Left it running. Came back for the college try and it works without rebooting. Still have issue with PinState #defines changed error.

    Hm 1 file per post. Here is the reset o/p from the Espruino IDE.

    I changed the clock code on spec that it may be running too fast. saw somewhere the clock was set higher by Espruino. I have another issue now. Using esptool.py to erase flash, everything is fine but it says this may take a while but ends immediately after. I tried loading the latest 1_89 and get this error. I'm just spinning my wheels now. I've attached a picture of the Espruino IDE reset o/p and my flash program batch file. Any suggestions gratefully appreciated.

    I tried this using the Arduino Ide.
    Here is the result.
    I was able to browse to the address and get the response from the 8266 but now it is resetting every 30 seconds or so.
    Have I messed up the watchdog settings? Do you need to configure them separately from the code?
    The newbie stage is so painful. Sorry to be such a pain.

    Hello Ollie,
    Hopefully I'm replying in the write place now. Sorry if not.
    I used the Espruino programmer and last time. I used esptool.py erase_flash this time.
    In either case, after erasing, I used esptool.py to program the module with Espruino code.
    "esptool.py --port COM4 --baud 460800 write_flash --flash_freq 80m --flash_mode qio --flash_size 32m 0x0000 "boot_v1.4(b1).bin" 0x1000 espruino_esp8266_user1.bin 0x37E000 blank.bin"
    I then loaded the simpler web server example from Kolban.
    "function beServer()
    var http = require("http");
    var httpServer = http.createServer(function(request, response)

    if (request.url == "/favicon.ico")
    if (request.url == "/hello")
      response.write("<b>Welcome</b> to the ESP8266 test.");
    } else if (request.url == "/goodbye"){
      response.write("<b>Please</b> come back again soon.");
    } else {
      response.write("Sorry... I didn't understand!");

    }); // End of one new browser request

    print("Now being an HTTP server!");

    } // End of beServer

    var ssid = "COZYPINES";
    var pwd = "";
    // Slow down clock
    var E =require("ESP8266");

    // Connect to the access point
    var wifi = require("Wifi");
    print("Connecting to access point.");
    wifi.connect(ssid, {password:pwd}, function(err)
    if (err)

    print("Error connecting to access point.");

    var ESP8266 = require("ESP8266");
    print("Connect says that we are now connected!!");
    print("Starting web server at http://" + wifi.getIP().ip + ":80");
    In either case, when I upload the server example to the module, first I get success. with an IP acquired.
    A short time 30s? later I get
    ets jan 8 2013, rst cause:, boot mode:(3,6)
    load 0x40100000, len 1396, room 16... there is more but I can't clip out of window.
    Bottom line is the module is rebooting. I have it running off the usb port. Is this the issue?
    I scoped the 3V line of the module and while I see noise (tx bursts) on the rail, it is in the mV are.

    I am also having trouble with resets. I have cleared 0x00000, through 0x300000.
    This started when I tried to save code to flash. the write seemed successful but after this I've had problems. Kolban's example simple web server crashes/reboots as below whereas before It would run properly. Sadly, I have a second virgin nodemcu module that I also programed with 1.87 and it also resets. Any suggestions on this issue as well as a comprehensive way to clear all flash.? Any help greatfully accepted.
    Regards, Jim Brooks
