I've just recently installed the Arduino version 1.8.0 IDE and loaded the third party ESP8266 extensions. I've seen these same messages as well. However, it does seem that the code is being downloaded and is running on the board.

There is likely a bug related to these messages, and, perhaps they are an indicator that you should retry the download.

But, if you just want to continue to make progress, you should look to see if your board is actually running the software. (Perhaps you can ignore the messages and get on with it!)

matthew

P.S. If you want more attention given to this bug report, you should include specific details about what versions of the IDE, what board you are using, etc...

@mcolinj ,
You mean esp8266 what we got does not have software flashed into it and we need to flash it externally using esptool ?
How to see if my board is actually running software or not.
I am using arduino-1.6.12 IDE and esp8266 board.\

Have you got it working now ?

TX---------------------RX
RX---------------------TX

If I use as per above configuration, I am getting following error while trying to upload the arduino IDE code-
error: failed reading byte
warning: espcomm_send_command: cant receive slip payload data

I have various forums and they suggested that

  1. GPIO_0 of esp8266 should also be connected to GND. I think putting GPIO_0 to GND will make it in flash mode. While trying to upload the code, I am getting below error-

warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed
error: espcomm_upload_mem failed

Also seen some diagram that they connected RESET pin of Arduino is connected to GND.

Please suggest what should be the exact connection diagram.

Try to connect The GPIO0 with a 10k resistor to ground and the CH_PD to VCC and it works :)

I ran into same Problems with flashing esp-01 modules.
While i need a bunch of them (>50 pcs) i ordered some CH340G-USB-Programmer from aliExpress.
they work well for flashing the esp-01 modules, but i still have to connect GPIO-0 -> GND and CH_PD -> VCC.

But then it works like a charm. I used both Arduino IDE (1.8.0) and esptool.
I'm running arch Linux .

When you use a simple UART-USB adapter to flash the ESP-01, take care of the power supply while most UART Programmers didn't supply the needed ~200mA for flashing the ESP-01.

Seems like this thread is basically the same problem.

Did this work? Just signed up yesterday, but there should be a link to a similar problem above.
However, I'll also copypaste my post from there into here, because I had the same problem and got it working now (even if there is still the problem of the esp seemingly hanging up after a couple minutes):

Copypaste begins here:

TL,DR: I solved my problems (warning: espcomm_sync failed etc.) by replacing the 10k resistor between GPIO00 and GND I used first with a 3.9k resistor.

Long Version:
I was also starting to feel a little irritated after sitting in front of this problem last night and today. But just about an hour ago I managed to solve my problem.
Initially my Setup is the ESP-12S on the typical white adapter board. VCC to 3.3V, GND to GND, CH_PD (or EN on other chips) and GPIO02 pulled high with 10k (although CH_PD should be high anyways with the layout of the adapter board, turning the two parallel 10k resistors effectively into a 5k), GPIO15 and GPIO00 pulled low with 10k (although GPIO15 should also be pulled low by the 10k on the board thus making the duo 5k as well). 0.1uf and 47uf are placed across VCC/GND. Power is supplied by the PSU from the Elegoo "The Most Complete Starter Kit". USB-to-Serial is done with one of these
http://www.ebay.de/itm/272461294802?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
, connecting the TX/RX/GND pins. For programming I use the Arduino IDE 1.6.12 with the esp-library.

The problem: I get the
"
warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed
error: espcomm_upload_mem failed
"
messages. Turning up the verbosity during upload reveals these lines as well:
"
trying to connect
flush start
setting serial port timeouts to 1 ms
setting serial port timeouts to 1000 ms
flush complete
espcomm_send_command: sending command header
espcomm_send_command: sending command payload
espcomm_send_command: receiving 2013 bytes of data
read 0, requested 1
error: failed reading byte
warning: espcomm_send_command: cant receive slip payload data
"

It is the Serial Monitor that will give me an idea what might be the problem:
On 115200 Baud it shows me something like this:
"
garbage_data (This is actually the bootloader reporting stuff on 74880 Baud)
AI-Thinker something something

ready
"
On 74880 Baud it reports a bunch of stuff, but most interesting is the very first line:
ets Jan 8 2013,rst cause:2, boot mode:(3,6).

Testing reveals: When connecting GPIO00 to high for normal boot - the Serial Monitor shows exactly the same.

Oh.

Ahhhh!

No wonder I can't program the chip if it isn't even in the right mode!
The 10k resistor seems to be too much for GND to properly register at GPIO00, thus not starting the UART Mode (programming mode) but Flash Mode (normal boot) instead.

I replaced the 10k (probably, I mean, I didn't measure it, but the other ones from the same batch from China seem to be 10k) resistor between GPIO0 and GND with a 3.9k. Voila,
"
writing flash
................................................................................ [ 34% ]
................................................................................ [ 69% ]
..................................................................... [ 100% ]

" (and some more lines before and after).

Also, the proper behavior of the Serial Monitor when starting the esp in UART Mode seems to be to show only one line of garbage data on 115200 Baud which is revealed as
"
ets Jan 8 2013,rst cause:2, boot mode:(1,7)
"
on 74880 Baud. Dates might differ, of course.

So I got exactly these error messages on a ESP8266 mounted on a dev board. To resolve the problem I had to keep the flash button pressed while flashing (output below). Here's a screenshot of my board with the flash button highlighted

I had the same problem and fixed with the following 3 steps:

  • I connected D3 to GND and D8 to GND with simple jumper cables.
  • I took out every single USB device connected to my machine. (Keyboard, Mouse, Monitor extension)
  • Upload the Bare Minimum Sketch

@devfilipe

I had the same issue using NodeMCU Amica. I got it fixed just starting the upload process keeping FLASH button pressed. After upload starts the button can be released. No external supply. No external resistors.

On Arduino IDE (assuming package esp8266 is installed), select Board NodeMCU 1.0, baud rate 115200.

@darrenolson
Copy link

I had tried all of your suggestions and what made my set up work - ensure good connections and proper VCC level

I have 55 Esp8266 to set up and all work now thanks to fixing poor wiring connections.
GPIO0 is grounded all the time, directly, not through any resistor.

TX---------------------RX
RX---------------------TX
3.3V-------------------VCC
3.3V--------------------CH_EN
GND--------------------GND
GNO--------------------GPIO0

@KaneIbrahima

I solved mine by connecting the reset pin to the arduino's reset. I believe connecting to gnd and a button would also solve it. I restarted and it worked. I tried another program and it did not work at first but when I reset it it worked again.

The espcomm open failed error is documented. If what the doc says doesn't work, you either have bad wiring, or a bad board.

The following error can be rectified by ,,
Connections:
tx -->rx(esp)
rx-->tx(esp)
3.3v -->ch_pd +vcc(esp)
GND -->Gnd +Gpi0(esp)

Better to make a switch for ch_pd pins this helps to enable flashing and rectifies the below error.

baudrate supports for me is 9600,57600 that works for me,

As many people wrote: basic problem with Arduino UNO is, that usb programmer isnt enough strong power. You have use external power supply (3,3V and wirted GND with usb programmer)

About above comments: NodeMCU 1.0 doesn't need Flash button to be pressed on upload. On the others models, if there is a FLASH button, it must be pressed on upload until Dots begin to apear, when the FLASH button can be released.

If there isn't a FLASH button, GPIO00 must be connected to GND.

I have Lolin NodeMCU V3, I followed, these instructions and to upload use NodeMCU firmware programmer, you have to hold down the flash button and then press the reset button. That's the only way I go the NodeMCU Firmware programmer to work.

From there I was able to upload a sketch by doing the same flash/reset buttons sequence.

I feel like I've tried just about everything here and it still doesn't work. There must be something I'm not seeing. I am using an arduino uno and an ESP8266 wifi module. The arduino is connected to the laptop, and I'm using 2 AA batteries as external source (they are brand new). My connection is the following:

ESP GND --> Arduino GND + AA batteries GND + GPIO 0
ESP TX --> Arduino RX
ESP RX --> Arduino TX
(have tried switching RX to RX and TX to TX but still nothing)
CH_PD --> ESP VCC which is also connected to the batteries

I have tried changing the upload speed on every change I make but still same error. I have even tried wiring the reset on the ESP to the reset of the arduino. I just don't know what else to try.

I still keep getting the same error.

For those looking for a solution, I had he same problem and I solved it with the following config:

Hardware:

  • Button between GPIO0 and GND
  • 10k resistor between EN and VCC
  • 10k resistor between GPIO15 and GND

Software (Arduino):

  • Board: Generic ESP8266 module
  • Flash mode: QIO
  • Flash size: 4M (1M SPIFFS) <- This may vary for your project/module
  • Reset method: none
  • Upload Speed: 115200

Procedure:

  1. Keep pressing the button (GPIO0 will be connected to GND)
  2. Connect the module to the power supply (VCC to 3.3v - GND to GND)
  3. Press Upload in Arduino IDE
  4. When the uploading start (you will see dots filling the console window) you can leave the button

Try to connect The GPIO0 with a 10k resistor to ground and the CH_PD to VCC and it works :)

I have the same problem , i try every forum solution but no success !
I try your tips here to and i start to wonder me , this is a cheap board maybe the solder of the wifi module are faulty , so i bring my iron and resolder it and add some more solder ..and now works like a charm no resistor no jumper cables.. just the usb cable !
