Let's Control It

Hi

I did a flash bith blank 1MB but still wifi , config and rules are on the ESP stored.
How to completely erase the flash?

btw: is the SPIFFS inside the 1MB?

Thanks

I also want to flash completely. Did you find any solution yet? If yes, please let me know

You could try with the esptool.py script. It is a Python script so you must have Python installed.

It has an option to erase the flash chip not by writing data to it, but to actually call the internal flash commands of the chip itself to perform an erase on all blocks.
It should also be faster to erase a complete chip.
