Is this the same as https://github.com/esp8266/Arduino/issues/1335?

Also would be cool if you provide the link to the source of HX711_Init function, since it is obviously causing issues.

thanks ,the code is :

define DOUT 13
SCK = sck;
DOUT = dout;
set_gain(gain);
COEFFICIENT = scale;
pinMode(SCK, OUTPUT);
pinMode(DOUT, INPUT);
digitalWrite(SCK, LOW);
if (is_ready())
{
read();

EagleSmith

I tried compiling your example, but I am getting an error that connectWifi is not defined. Also in your hx117_init function, read function is not defined. Could you please post the complete source code?
It is also not clear why you are getting messages related to SPIFFS if you are not using it (at least not in the code you have posted).

If you are getting an exception, please post the exception message here and decode it using EspExceptionDecoder tool.

And for those of us who are less psychic, where would I go to change this PROGMEM const int??
john3exonets
on 18 Dec 2016
Ditto, would be nice to know exactly where to change PROGMEM. Few things I already searched, my Arduino IDE folder and this location where the IDE places upgraded libs: C:\Users\myuser\Documents\Arduino
I also found PROGMEM referenced in ArduinoJson lib which seems to say that PROGMEM is only available in AVR architecture which contradicts what we have with the ESP8266 (non-AVR):
// PROGMEM is only available on AVR architecture
My project (SmartThings generic HTTP driver/Device-Handler controlling 2 relays & more) is much larger than the few concise samples posted above but this error is killing me and made me put in reboot logic, occurring every 8 hours; pathetic solution... posting that reboot sample below for others to reference but it's a crappy workaround and we'd love to get this figured out, please elaborate on the proposed fix.
//SELF-STANDING FUNCTION AT THE TOP OF THE SKETCH OUTSIDE OF SETUP/LOOP
void(* resetFunction) (void) = 0;
//AT TOP OF THE LOOP --- RESET EVERY 8 HOURS
if (millis () >= 28800000) {
resetFunction();
}

What is the meaning of this "boot mode:(3,6)"??
There are also other types of boot modes, what do they mean??
Please provide any table that has all possible values and meanings of boot modes.
Please help. Thank you....

Hi
I am getting the same problem in a D1 mini (ESP8266 based board).
"ets Jan 8 2013,rst cause:4, boot mode:(3,6)
wdt reset
load 0x4010f000, len 1384, room 16
tail 8
chksum 0x2d
csum 0x2d
v09f0c112
~ld
"
When i go the webpage to know which is the problem here, i find: That reset cause 4 is watchdog reset,
and the modes are:
Number | GPIO15 | GPIO0 | GPIO2 | Mode
-- | -- | -- | -- | --
0 | 0V | 0V | 0V | Not valid
1 | 0V | 0V | 3.3V | Uart
2 | 0V | 3.3V | 0V | Not valid
3 | 0V | 3.3V | 3.3V | Flash
4 | 3.3V | 0V | 0V | SDIO
5 | 3.3V | 0V | 3.3V | SDIO
6 | 3.3V | 3.3V | 0V | SDIO
7 | 3.3V | 3.3V | 3.3V | SDIO
So my personal guess is that my D1 mini is in " flashing mode" right? So the issue is to put it in the "running mode" right? Any suggestion on where to look to do that? (I am not very proefficient in this things ..)

This looks like user error due to use of wrong pins, or use of 3rd party lib that wasn't supported for the ESP.
Closing per #3655 .

Absolutely, after the same error, my code worked perfectly, without any need for better POWER-SUPPLY....
it was just a 'Wrong, Unsupported 3rd party library' !!!!!!

Reason(in my case):
pins RST(reset), EN(enable) and VCC were facing fluctuations in power supplied irrespective of the constant power supply. This was causing a rst of no. 4, i.e. Hardware WDT reset.
Solution:
Add a 47uF capacitor at each of the pin mentioned wrt GND.

i used 47uf capacitor to RST,EN and VCC wrt GND but still having program,
IC esp12e is flashing properly but still not working.
after some time serial monitor shows following error.

@koltevinod1
I actually had a code that did THIS:
typedef struct
{
int a;
int b;
}AB_struct
AB_struct* ab = NULL;//AB_struct pointer. Init to NULL(0)
ab -> a = 23;//Tries to put data into address 0!! => wdt_reset();
ab -> b = 45;//Same as above.
In ESP8266, if you access the area around pointer NULL, the program goes into watchdog reset. This was hard to find but when I fixed that Wrong address access, the problem was solved.
Conclusion : Watch out for your mistake in the software where you access NULL pointer as a valid pointer on ESP8266.

Thank you for your reply..
fist thing is i am using arduino IDE to build and upload a program for esp12e.
but i am trying to upload any of a code then what happen is,
- its uploaded successfully up to 100%
- nothing is happen then for some seconds i.e. program is also not running.
- after some time
wdt reset
load 0x4010f000, len 1384, room 16
tail 8
chksum 0x2d
csum 0x2d

this error is occur on serial monitor.
and between some it repeatedly come,.
A am not able to find out what exactly happening, What wrong with it???
Please give me a solution.

if I upload normal blink program it works fine but when I upload minimum bare program to access the AT commands I get above error. And also this error comes only in baud rate of 74880 which I didn't configure anywhere before.
Kindly let me know the reasons and solution for above error.

Once I had a similar problems, not sure if the same.
it turned out that I was not declaring properly the pins. For instance, PIN 1 in the arduino IDE code, is not PIN 1 in the D1 mini. I just looked the pinmap change the pins and it worked OK.

@Kondenado thanks, I also moved from Uno to D1. Your suggestion solved my issue!

Any solution ? tutorial ?
Maybe you are not using the right version of the Library.
msalik42
on 10 Jun 2019
@msalik42 you should read the comments from @junwoo091400
"In ESP8266, if you access [...] a null pointer [...], the program goes into watchdog reset."
I would recommend you double-check all variables and pin numbers, make sure they have been initialised and have correct values.

I'm facing the same problem of many people with the reboot of the esp8266 board.
I'm using the arduino lib as it is , why it is not working directly ? on the 8266 arduino file there is more the 500 structure which one is wrong .
I'm using ESP-01
The STA mode works TCP & UDP, the AP reboot TCP&UDP
Thanks

rst cause:4, boot mode:(3,6) often happens when you define the pins incorrectly. For example, I was using a Wemos D1 Mini and specified constants to define pins 6 and 7, whereas I should have put in D6 and D7. EDIT: oops, noted above this has already been mentioned.

Also get rid of the wifi declare ESP8266WiFiMulti WiFiMulti; and change to WiFiClient wifiClient; instead and use that in your code.

Do you have the latest libraries installed and updated?
Have you tried another Wemos D1? I've been delivered one in the past that just failed like this all the time, regardless of the code I had on it. Although, if Blink works on it and this code doesn't, then that kind of points to the code or library.

Yes, my other Wemos D1 works fine, but this one was also okay just a couple weeks ago, and I did only sketch changes.

Fixed my issue with:
Reduced the main delay to 3000 in loop (presumably the cause of wdt reset), dropped wifi multi, and I was getting a new error:
Fatal exception 3(LoadStoreErrorCause)
I did some more searching, and found this thread that suggests erasing flash.
I changed the Erase Flash in Aduino to "All Flash Contents" and it helped.
