ESP32 Firmware Backup Assistance
Budget: $30 – $250 AUD
I need a reliable, step-by-step walkthrough for pulling a complete firmware image off my ESP-32 over USB so I can keep it as a safety backup. The board is powered up and reachable, but I’m still undecided on which utilities or drivers to install.
Here’s what I’m looking for: guide me in choosing and installing the right tools—esptool.py, Espressif’s Flash Download Tool, or any other method you know works—then walk me through the exact commands to read the entire flash and save it locally. Once the dump is complete, help me verify its integrity so I’m confident the backup can be flashed back later if needed, and assist with flashing new device.
The deliverables are simple:
• A verified binary file containing the current firmware
• Clear, repeatable instructions I can follow on my own next time
* Assist with flashing new ESP32 device with firmware
If you’re fluent with ESP-IDF, esptool, and USB-to-UART drivers, I’d love your help.
