problem coming after uploading program....

rst cause:4,boot mode(1,6)

GPIO's status after uploading code
CH_PD--VCC
GPIO 15--GND
GPIO 0-Connected to DC MOTOR via N-MOSFET
GPIO 2-Connected to interrupt pin for sensor.....

once MOTOR start rotating after 10sec it throws wdt reset......
previously it is not giving problem with this setup at normal load

@sarwadenj no sketch, no basic info, no IDE settings.
Closing due to lack of info, see #3655 . If the problem still exists, please open a new issue, and provide the details requested in the issue template.

I just started getting exactly the same thing after flashing:

wdt reset

It happens with any sketch, including

void setup() {
  // put your setup code here, to run once:
}
void loop() {
  // put your main code here, to run repeatedly:
}

I'm using the Arduino IDE 1.8.5, and Generic ESP8266 Module on a Ledunia. This Ledunia was working perfectly. I looked through #1013 without success.

If I reset by shorting RES to GND, I then get an infinite loop of

load 0x4010f000, len 1384, room 16 
tail 8
chksum 0x2d
csum 0x2d
v3de0c112
~ld
[...byte code...]

This seemed like #2414, but I am powering from the same place as when it was working (a USB port).

The whole thing started after uploading a sketch that was setting pin 13 as output. Could that be the reason? Any thoughts are welcome.

Hey everyone..
I'm getting this in serial monitor of arduino... please suggest some solutions, I'm unable to check my desired output.

Please help ASAP..!!!

Thanks.

For some reason, after a few weeks of not touching the board, I no longer have the problem.

[dangsonbk]

I got same error when my code looped in while(1);. Seem that the board was reset by watchdog.

Have no solution?
I got only this message when GPIO_0 is GND:
" ets Jan 8 2013,rst cause:2, boot mode:(3,6)

ets_main.c "

Nothing more.
And I got this message when GPIO_0 is VCC:
" ets Jan 8 2013,rst cause:2, boot mode:(1,7)"
Nothing more.

I have clicked "Erase" button on ESP8266 Download Tool V.3.6.8, and the prompt shows this message:

CONNECT BAUD: 115200

To everyone having the same Problem as the OP. I had it too.

The Problem is, that the ESP8266 crashes during the rotation of the stepper motor because it can not handle the WiFi tasks that continuisly run in the background while only having a few microseconds delay.

I added the yield(); function to my rotation loops and the crashes are gone.

At least that was the Problem with me, since we are basically doing the same thing and i had the problem i assume this would be the solution for this case too.
