How was the explanation?
It was tough for me to explain the things clearly still I tried my best.
nice explaination without hesitation , superb , very though to explain these kind or error to someone ,
Thanks. Do share it so that, maximum number of people can get to know the solution
In the next video can you explain us about error : esp is not responding.
It happened while i was running the esp8266 01 with arduino uno.
Too slow i guess... keep up with your regular speed
How to re program the board after a code plz tell me
This is a great video, thank you for posting.
For about a year I have been programming WEMOS D1 MINI v 3.0.0 without any problems whatever. I am currently working on a project using DS18B20 temperature sensors which is progressing well. However I downloaded a programme from TH-cam which compiled OK but would not upload, giving the error you mentioned above. Following that I could not upload any programme, not even a BLINK sketch! I tried all the usual things, replaced the USB cable, tried a different board but nothing worked. I even re-installed the IDE.
Then I tried your solution, grounding GPIO0 (D3 on the WEMOS) and it worked. Not just that once but I am back to normal uploading once again without having to do the grounding. Not sure on how this has worked but it has I am eternally grateful for the solution.
Thanks a lot man, I almost gave up my NodeMCU. Until I saw your video to press flash button before plugging it to USB port and release it afterwards. God bless you!
You are the best . I was unable to program my esp8266 from past 1 month but now i am able to program it.I was able to program it after conecting reset pin to ground.Now i have both esp8266 and node MCU working.
Thank you from Spain, sir! Worked like a charm for my new NodeMCU (I was about to give up). You're #1.
After searching 2 hours on internet without success you solved my nodeMCU problem.
Thanks for this easy solution
No one else showed that Reset to GND connection in their schematic. As soon as I did that it started working
thank you!
whenever someone explains a techie thing with indian accent, I know it's good. thank you!
Thanks a lot! My problem was that I selected the Generic ESP8266 just like the datasheet says... It's must select the NodeMCU 1.0. Very helpful. Greetings from Venezuela!
This helped me alot. 3 days solid no progress and this solved my problem in 2 minutes.
In my case when I upload the example Blink program, the LED blinks a few times before the IDE displays the error and when I disconnect the power and disconnect GPIO0 from GND and repower it just blinks one time, what could be the problem?
Thank you very much! It is worth also removing any cable connecting to your ESP8266 Node MCU. Removing cables and your hint saved me! Thank you!
all the way from Zimbabwe man thanks keep up the great work
your video with the most helpful i get to understand the concepts of esp8266 communication port>> thanks
So far the Best video for solving this error...very well explained each and every reason... Thanks a lot
thank you"
techiesms"this solution is works 100% for my
NODEMCU V3
"espcomm_upload_mem failed"
Really appreciate all your efforts to explain these stuffs. Kudos, man :)
Thanks for helping my final year project sir ! Nice explanation.
Thanks a lot!!! I am glad finally my problem is solved. None of the websites showed that one should even check cable
Superb explanation, sir. All doubts cleared about this error. Even I got the error. Thanks a lot. Excellent!!!
THANKS! finally someone that could help me, my fault was just some stupid wiring, haha.
even though i have done the process which u have have mentioned above ,i was getting same error as mem failed
thanks buddy!
i was trying to solve this error from soo long, and now finally its gone!
Got to know about the errors properly..thank you..!✌️
Thanks a lot bro! You seriously gave me a big help in the last minute! I owe you bro! Thanks a lot
hi, here you said arduino reset should be connected to GND. so that the esp module works. well i want to use them both. i mean like i get data from esp and print them on 2x16 lcd. is it possible? cause when i diconnect reset from GND esp stop working and when i connect it arduino stops working! what do you recomend?
Vous êtes vraiment excellent Monsieur , je vous remercie beaucoup pour cette astuce.....
HI ...Your Solution on the error espcomm worked perfectly well..Thanks a lot
I am working on home automation project.. problem is that when power recycle in nodemcu it not work. And i have to uplaod again and again code. Please help me
Very helpful, its solved my upload problems :-) THANKS!!
Sir my error is that the blynk code cannot be compiled for my nodemcu board the error shows that "error while compiling for nodemcu(12-E)"
Thank you for your troubleshooting It's solved the problem for me after following your instruction.😊
At least I had to restart my PC ... now ist works!
I was about to throw out my NodeMCU. Thanks, man!
I've installed the esp8266 board again. Now it's working without this error.
Some corrections: 1. To confirm driver installation, checking windows device manager for com Port existence should have been explained. 2. In NodeMcu board funtion of reset button is not explained. Some of the YT videos are asking user to press and release while Arduino is opening the com Port for communication.
Thank you so much, bro, for this video, just because of you I was able to upload the code to the esp8266.
for my case, the reason why I get the error is the circuit for Rx is connected to a voltage divider and the input is only from the USB cable. so I try to connect the esp8266 Rx pin directly to the Arduino Rx pin. and it solved
Thank you for your troubleshooting It's solved the problem for me after
Hi, I am facing the problem and tried as instructed in video but still the error persist what could be the possible cause.
Man, thank you, life saving video!!!
Very Useful, i fixed my nodemcu v3 ch340, Thanks a lot
how?
Thx guru your explanation exactly works for me, and it solved my error problem
i have this error

i dont know whats up
can you help me?
i am getting d8 is not declared in scope in ep8266 cp2102
while uplading code for led matrix using google assistant .
now what are the steps to be taken for this plz help
hi , im having the same problem, when i compile the coding ,can you tell me the way to fix it?
These type solutions what we need ! , very thanks techiesms
La placa apropiada para que no salga el error "error: espcomm_upload_mem failed" es NodeMCU 1.0
La genérica ESP 8266 es otra placa más pequeña que solo trae el módulo wi fi y no es la del video.
Under TOOLS / reset method, select nodemcu. worked for me.
You are amazing!!!!! This solution works very well.... THANK YOU
Hello,
I am using Version 1.1.bin. Everything was ok since I tried to change the ssid from pwned to another name. In the same step I also changed the wifi Password and clicked "save".
After that the new ssid is displayed, but when i try to connect, the new password is not accepted. I was very carefully when changing the password and i am sure that i wrote it correctly.
Also the old password "deauther" doesnt work.
I flashed the esp8266 again, hoping that would set everything to default, but after that it Shows the new given ssid again and no Login possible.
Any ideas?
Sir In this connection had any resistor for Ch_pd like 10k and for rx 1k resistor
Thanks man it solved my problem thank u so much
WOW THANKS!!!! Saved sooooo much time!
Thank you sir! Solved my problem!
Many thanks for making great video ...
thank you very much , you help me a lot , your explanations are very good
Thank you very much man, it helped me a lot!
Thank you. Flashing worked for me.
should i do this everytime i want to upload my codes?
Thanks sir very useful
worked for my esp8266 module
Can you please tell what you have done?
Alhamdulillah,
Your video help me solve my problem
Thanks man, You are a lifesaver
That helped me so much. Thank you so much man!!
I want to test if the ESP8266-01, is working at first don't I? Your video is excellent if I want to upload a sketch to the ESP8266-01. But before I can even hope to be able to upload anything, I would think and am still trying to basically make a connection and communicate with AT commands . So far, I have not gotten one to work. If you can suggest a very basic instruction or video showing me how to do just that, I would be eternally grateful to you. There are so many conflicting statements out there, that I don't know which is correct.
Can you suggest me website,book or online course to learn program to make my own esp project
when face detection and recognition turn on, why esp 32 cam is black and serial monitor is martix3du item alloc failed?
I fixed my SYNC error with cp2106 drivers from here!
Worked for pressing the flash button while connecting to usb withh the nodemcu
Genric esp8266 12 e having problem in arduino ide and other firmware erorr show com port not open and some times an other error. Drivers is already installed my system and and also checked cable but also facing this problem. Make a video how to clear this error
I followed all these things but still I am getting error while compiling even I change a laptop also but it showing the same error, pls help me solve this

thank you, you solved my problem
thank you so much i can do better today using esp8266
Amazing video, thanks a bunch!
This Indian god saved me
Hei, now do you know how to reset ESP8266, cause now every i turn on it it always show my last code
Great video. Thanks for the help
Hi, I was having same problem, your options are too useful, however in my case it doesn't help me, I solve my problem choosing in Tools a board NodeMCU 1.0 instead of Generic ESP***, you could try it too, anyway thanks for your help.
Tenkiu men we love you no homo =D
