The full binary also contains a bootloader and partition scheme needed to properly boot the ESP32.
Before starting the flash process you have to put the ESP into flash mode:

GPIO0
is connected toGND
- Start the flash process
The actual procedure to flash the ESP32 depends on the tool used. Click on the tab below that matches your flash tool.
