ESP32 Forum

Is there a SW tool that would allow me to upload from the ESP32 memory?
Maybe something like the flash_download_tools_v3.4.4 , just in the other direction and that would allow me to also read the fuse settings.
I'm working off a Intel PC running WIN 7 using a DOIT v.1 development module.

Hi agkirk,

There isn't a GUI tool that I know of, but there is a command line tool - esptool.py is included in ESP-IDF and can do both these things.
https://github.com/espressif/esptool

"esptool.py read_flash" can read flash contents to a file.

The bundled espefuse tool can read out efuse contents and also burn efuses.

If you're using ESP-IDF on the MSYS command line in Windows, you can run "source add_path.sh" in the IDF directory and esptool.py and espefuse.py will be added to your path.
