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!


Commands Used in This Project

1. Read Flash Size:
esptool.exe port COM3 baud 921600 flash_id

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
