I have a question for you. Do you know of a way to install a OS from a keyboard like the Ensoniq EPS Classic or old Akai MPC drum machines on an ESP 32?
I need to read memory from esp32-wrover-e which is not connected to a development board. What programming cable will work and what peripherals do I need in order to read and write?
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.
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?
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?
Nice Video! But i have a problem, the download stop to 16%. With the error: 679936 (16 %) A fatal error occurred: Packet content transfer stopped (received 3974 bytes). can you tell me what could be the reason for this?
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?
Is it possible to convert the download file of the esp 32 or esp 8266 to the Arduino ide sketch ino file Means convert.bin file to .ino file Please respond if it is possible
I am trying to do ,but after uploading the file error is coming ,in error esp8266tool.exe file not showing. Secondly from note book copy portion pasting in windows and press enter, direct command window is opening.
Sir agar muje esp32 ke andar ka code copy karna ho without lost code jo ki us esp me already upload hai to mai kaise karu mere ek project me maine code upload kiya tha but vo laptop mese Delete ho gaya aur muje vo code urgent chahiye isliye aapko pucha please bataiyega sir 🙏
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.
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!
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?
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
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
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
There are ways to protect your ESP32 code from being read or cloned, though the ESP32 is not as secure as some microcontrollers that are specifically designed with code protection in mind. Here are some methods to help secure your code: 1. Flash Encryption ESP32 supports flash encryption, which encrypts the contents of the flash memory. This makes it difficult for anyone to read or clone the code directly from the flash memory. You can enable flash encryption using the ESP-IDF framework. This feature ensures that all data written to the flash is encrypted, and it can only be decrypted by the ESP32 itself. To use flash encryption, you need to configure it during the initial programming phase. Note that it can impact performance slightly due to the encryption and decryption processes. 2. Secure Boot Secure Boot is another security feature provided by the ESP32. It prevents unauthorized code from running on the device. With Secure Boot enabled, the ESP32 verifies the integrity of the firmware using a digital signature before executing it. This prevents anyone from modifying or uploading unauthorized code to the device. To enable Secure Boot, you will need to use the ESP-IDF framework, as it is not available through the Arduino IDE. 3. One-Time Programmable (OTP) Memory ESP32 has OTP memory, which is used to store keys and other security data that cannot be changed once programmed. You can use this to store a unique identifier or encryption key that ties the firmware to a specific device. You can also set certain bits in the OTP memory to enable security features permanently, such as flash encryption or secure boot, making the device much more difficult to reprogram. 4. Disabling the JTAG Interface The ESP32 includes a JTAG debugging interface, which can be a security risk if left enabled. Disabling the JTAG interface prevents anyone from accessing the chip for debugging or code extraction. You can disable JTAG using software commands or by burning a specific OTP bit to permanently disable it. 5. Firmware Update with OTA (Over-the-Air) Instead of programming the ESP32 through USB each time, you can set up Over-the-Air (OTA) updates, which can be password-protected. This allows you to control when and how firmware updates happen without exposing the device's flash memory. 6. Preventing Multiple Flash Writes While the ESP32 does not natively support a "write-once" feature, you can simulate it by setting a flag in flash memory after the initial upload. For example, during the first-time setup, your code can write a unique flag to a specific flash sector that the bootloader checks on each startup. If the flag is present, the bootloader can prevent further reprogramming attempts. Combining these techniques, especially Flash Encryption and Secure Boot, will make it considerably more challenging for anyone to clone or tamper with your code on the ESP32. Keep in mind, however, that while these steps will increase security, there is no method that can provide absolute protection.

how do i re-edit the edited bin file
it is not possible
Thank you🎉
How to view a .bin file means coding statements programed by someone.
You cannot do that
Is there any way to prevent that, I don't want any One to use My code
