Espcomm Upload Mem Failed Adafruit Huzzah Esp8266

greetings -
Loading a sketch to the Feather HUZZAH using the Arduino IDE i.6.5
I'm getting:
warning: espcomm_sync failed
error: espcomm_open failed
This seems to be a "affair" but I'm not finding a solution.

While I'g totally new to Arduino, I'thou pretty tech savvy and then here are the details
- HUZZAH connected to Surface Pro (kickoff generation) via USB - WIndows 10
- Went through the Adafruit Learning documents so I accept...
the proper USB COM Commuter installed and selected in the IDE, I verified in the WIndows Device Manager COM5
the IDE is set up up with the proper board
- I copied the sketch examples directly from the documents - tried the blinking and the wifi test - both got the same mistake on upload
- I'g using the ane.6.5 IDE considering obviously 1.six.6 has some issues with this board.
- I practise not have information technology attached to a breadboard - from the box to the terminate of my USB cable and I've attached a battery.
- I did load a bunch of other boards into the IDE because I have some others still in the box that I'll become to somewhen.
- I've tried information technology with the tablet plugged in and not plugged in and with the HUZZAH with and without the battery
there take been references to lack of power with this flake simply this lath has the awesome battery arrangement that should make that a moot point.

So...any help would be appreciated...and for what it'due south worth - this is the first fourth dimension I've tried to do annihilation with an Arduino. Don't assume I know anything. I believe I did a pretty decent job of looking into this simply I'thou at a loss. I do have three others I oasis't opened all the same that I could try but this seems to be something that others accept encountered - and the theories are all over the map on information technology. This seems similar the place I might actually find the the right answer. It is a Adafruit board....

Brand certain the ESP8266 board library is also 1.6.5. It installs ii.0 by default. If you're on two.0, uninstall it and install i.six.5 then restart the IDE.

I too have the aforementioned problem, I moved to a the earlier version and things got a lot more complicated, now in the status box I become:

I installed version one.six.5 for both the IDE and the board, it seems to exist working

I'1000 getting the same trouble. I'm on OSX yosemite. I've tried IDE one.6.5 and i.6.4. Downgraded the ESP board to the 1.half-dozen.v-947-g39819f0 option. Pressing upload causes the red LED to glimmer three times so the error message displays. Hoping someone comes up with a fix. Thanks for whatsoever insight on this.

Bingo.... the older 1.half-dozen.5 lath worked for me.. thanks for the help. Now I merely have to find out how to get the mac accost and get to working on some projects. Need the mac to register on our campus device network. Back in 1994, I joked about having everyone carrying wireless network servers/admission points everywhere they went to form a mesh of wireless coverage and the ability to share information based on geographic location, proximity to other people and whatsoever other factors that information and combined with sensors embedded in mobile devices and physical spaces would allow. I never thought id be prototyping such things in my garage... which is better equipped than the office I have on campus/.

Thanks again for the help. Hopefully the documentation is updated with this helpful information.

I think I'thousand now having a related problem...I've been able to compile and upload the simple lawmaking that connects to my WiFi and and then pings AdaFruit. Great!

Given that, I moved on to the real project - in a nutshell, I am wanting to convert the project described in the link below to employ AIO rather the cloud services they are using. This adds the RGB Colour Sensor (Adafruit_TCS34725) to the mix. I oasis't continued the sensor but I've used information technology before with a RasPi. The trouble I'thou having is that the Adafruit_TCS34725.h library can't seem to find Wire.h.

Again, I am actually new to all of this. I'm pretty certain this is something simple that someone with more experience could easily indicate out. I just desire to go this thing working. I take a few of these boards and sensors of various types. The RGB sensor is my favorite and the key to a demo I'd similar to do at a conference - crowdsource the colors of my presentations and digital signage in existent-time by having several people walking effectually with these "collecting" colors for me. An interesting mode to present IoT to faculty and researchers.

The WiFi RGB Color Sensor "Conversion" Project

http://world wide web.switchdoc.com/2015/11/iot-es ... urce-lawmaking/

BTW - My skimming of the web gives me the impression there may be a special flavor of Wire.h for this board. My approximate is that the sensor library doesn't know that. I've tinkered with the lawmaking, adding the include for Wire.h in the primary lawmaking but coding isn't my forcefulness. I appreciate the input and help on this. I'm much further than I was - just from the help on this kickoff question. I'm hoping the follow up is just every bit fruitful. I think information technology is related to the lath and libraries so I'm keeping to this thread!

OK,

I have it working - only to hit this wall...in that location seems to be some sort of effect with the math libraries as per this thread:

http://www.esp8266.com/viewtopic.php?f=28&t=6043

I really can't spend besides much time on this - and to this point I've been bogged downward by the development environment more than than anything. There is a divergence between a normal learning curve and needless frustration. I wouldn't exist about equally far without the kind help of all the people hither but ideally, we'd all be past these sorts of things and focusing on the absurd ideas. I'm trying not exist negative but I've been spinning my wheels for days now and ignoring other deadlines - all the code I demand should be there to piece together if the libraries worked as advertised. I've been up for 36 hours straight trying to figure this out....

Here is the mistake bulletin...any thoughts?

I'1000 having the aforementioned bug (error letters, will not download) running Mac OSX Yosemite 10.ten.v on a Macbook pro, using Arduino IDE 1.6.v with esp8266 version ane.6.five-947-g39819f0. I could download the sketch to the feather HUZZAH board just once, then the errors begin occurring and information technology hasn't worked since.

I tin move the same feather HUZZAH board, battery and usb cable to a Windows auto (running Windows 7) and it works fine, no errors, no download bug.

Any solutions for the Mac?

I've found that on my mac I have to connect pivot #0 on the HUZZAH to ground to be able to program it reliably. This is non true on my windows computer, and I'g not sure why? But running a jumper from pin #0 to ground doesn't hurt annihilation on the windows system.

Cheers for your reply!

GPIO pin 0? The pinout indicates: "This pin is used past the ESP8266 to determine when to boot into the bootloader. If the pin is held low during power-upward it will start bootloading! ". The pinout also indicates GPIO pin 0 controls the carmine led.

I am besides getting the "espcomm_sync failed" message on Feather Huzza when only Uploading a sketch to it, counting on the automated bootloader to work. The cherry-red and blue leds glimmer once, pause, and couple more blinks, and the mistake message appears. However, the upload works if GPIO0 is grounded first, Reset push pushed, and GPIO0 disconnected from ground sometime during the window when the Arduino IDE is trying to upload on the series port (touch and go, oftentimes takes 2 or 3 upload trials).

Bottom line, my Feather Huzzah's automated bootloader does not seem to work. What else should I endeavor ?

Config: Win7 64b, Arduino IDE ane.6.6, followed the Adafruit instruction for setting up the Plume Huzzah (CP2104 serial port driver, Generic ESP8266 lath, proper settings: flash size, reset method, etc). Tried both my laptop'due south USB 2.0 and three.0 ports, same results.

past smkraph on Sunday Jan 10, 2016 7:23 pm

Follow-up: wow, no wonder my ESP / IDE don't play overnice when uploading a sketch. Attached is a logic analyzer capture of GPIO0 & RESET on a failed automatic bootload. Along with the DTR / RTS signals from the CP2104 USB/Serial controller (those signals are used by Adafruit to generate the GPIO0 & RESET signals, co-ordinate to their schematics).

This sequence is repeated 3 times total before the "esp_comm failed" IDE message appears. Note1: in that location is no circuitry whatsoever on my breadbaoard that's fastened to the feather Huzzah (just using the USB cable, nix externally connected to GPIO0, RESET, anything). Note2: tried information technology on the second Feather Huzzah board, same thing.

Seems garbledigook timings. I'd have expected GPIO0 to be a make clean long low (following DTR) and RESET to pulse low one time (for example when RTS goes upwardly, in the eye of GPIO0 existence low).

What's up with this sequence, Adafruit fearless designers ? Seems to me there'southward a snag in the DTR / RTS sequence and/or the transistor logic generating GPIO0 / RESET.

by mbishton on Sun Jan 10, 2016 9:32 pm

I recollect Adafruit has a responsibility to publish a configuration that works; that anyone, including novices, can follow. I code a lot but am new to these devices. I shouldn't have to waste product days trying to become this to work. I tried an Arduino UNO and it worked immediately.
I use a laptop running Win eight.1, installed Arduino IDE 1.half-dozen.5. I likewise followed your other instructions, except that I did not supervene upon the LUA, because in that location was no statement that it is required in order to work. I get the same fault message. I bought three of these so that I could learn IoT, and these seem pretty cool. If they worked. Please set up this and provide clear instructions.
