How To Read Bin File From ESP32 and ESP8266

In this video, I'll show you how to extract hex code from an ESP32 or ESP8266. We'll use the ESP32 development module for this demonstration, but the steps are the same for other devices. After uploading a blink sketch to the ESP32, we'll extract the code and upload it to another module. This process allows easy cloning of functionality across multiple devices, saving you time and effort in programming. Let's get started!

2. Read Bin File From Flash Memory:
esptool.exe --port COM3 --baud 921600 read_flash 0 0x400000 esp32blink.bin
3. Write Bin File on Flash Memory:
esptool.exe --chip esp32 --port COM3 --baud 921600 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_freq 80m --flash_size 4MB 0x0 D:\esp32blink.bin

It really worked, even on ESP8266! Now I address it to the other viewers: regardless of whather you use, ESP8266 or ESP32, you should install ESP32 support on Arduino IDE ->Boards Manager, do all as Ahmad did. Later in "Write Bin File" (8:49) instead of "--chip esp32" use "--chip esp8266" And that's all the difference :)

[@DIYELEKTRONICKITS]

Works fantastically, wow thanks for such a great tutorial.

[@nicolassun7938]

I tested it and it works great ! Many thanks for your very good how to. Continue to make very good video like this.😁👍

Hi, Do you also have video link for encrypting ESP32 to prevent cloning. Thank you.

Tks, very usefull but for the LOLIN C3 MINI the read operation start without pressing the RESET BUTTON and the procedure doesn't arrived to the end of the memory (error come after a while...). Someone can help me?

[@Steven_Bennett_YT]

Excellent, very helpful. I notice the download time is much longer than the upload time, is this because all 4Mb is downloaded but only the actual sketch binary part is uploaded?

[@sivashankar5500]

[@mainegrower]

I need to be able to edit the extracted file. How do I convert it so I can bring it back into arduino studio to edit it.

[@Chache17]

I have a couple questions: is it possible to password protect the esp32 so that this operation can only be done with the correct password? And, is it possible to just copy the program partition and paste it into the second device? This is to keep the data potentially existing in the spiffs partition.

Hello Sir, Please share your program that to use in the dekstop

[@ПерсеяПегаса]

thanks bro

[@sulesharad]

Good day sir, In this tutorial you have used esp32 module and you said steps will be same for esp8266 .that means wherever you have mentioned esp32 in prosses. i should mentioned esp8266 instead of esp32 right. Secondly you have select randomly esp32 development board, for esp8266 which board i should select. Please guide With regards Sharad

[@chrisb.9865]

hello sharad, for the esp8266 you can do it exactly like he did. I just did it and it worked fine using the esp32 module and dev board config. but with my esp8266 board i had to slower the baud rate to 230400. best regards, chris

[@fahimi.saiyed8939]

can i convert bin file to .ino or c file?

[@Euro-np8mp]

Yes you can.

I had a project on my ESP8266 that works but, I lost the code after my HD crashed. Is it possible to retrieve the code from the device, so I can make a copy and edit/save it? (I really want the code back) I spent a lot of time working on that code and, I hope I can bring it back from the device.

how to open esp8266 bin file on computer

[@jumbo999614]

I'm using Proteus simulator and it expect hex file for microcontroller. When I compile code for ESP8266 in Arduino IDE, I get elf and bin. Can I convert it to hex? Even it successfully converted, will it work in proteus?

[@hsnhaku319]

Thank you🎉

[@ethanclement9647]

You're a genius and thanks for your careful documentation. I was able to pull the file from a "dead" ESP32-WROVER-E device. I did have to cold boot it with power supply and then it locked into bootloader mode nicely. Thanks again!

Did you set correct COM port number? When you don't connect your board to PC, defalut COM port on Arduino IDE is COM3, but when you connect your board, this COM port number mostly changes. Check your COM number after connecting your board and use correct COM number in CMD

[@praveenb9048]

Hi, I am using a Raspberry Pi for development. The path to esptool points to a Python file, esptool.py. I tried to do "python esptool.py -version" etc, but it throws an error. Any ideas how to use the python version of esptool? Thanks!

[@praveenb9048]

I tried running esptool.py in the same original folder, and the 'version' command works ok. Is it safe to use from this location for the rest of the process?

[@praveenb9048]

OK, I just copied all other stuff from the same folder along with esptool.py to another folder, and it works.
