• Usually Espruino doesn't load code if a button is pressed at boot, but unfortunately it looks like on the normal ESP32 build no pin has been defined for this, so I'm not really sure there's a way.

    You could always boot to the bootloader mode and then erase the first page of Storage (at 0x320000 I think?)

  • Any hints how to set-up a "button" pin?

    I ended up checking for certain pin in my code which I short or pull up when needed.
