 ### Flashing binaries with [esptool.py](https://github.com/espressif/esptool)
 
 Linux:
-```esptool.py --port /dev/ttyUSB0 write_flash 0x0 binary-file.bin```
+```esptool.py --port /dev/ttyUSB0 write_flash 0x0 firmware.bin```
 
 Windows:
-```esptool.py --port COM1 write_flash 0x0 binary-file.bin```
+```esptool.py --port COM1 write_flash 0x0 firmware.bin```
+
+With ESP32 it is a bit more complicated:
+```esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 460800 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_freq 40m --flash_size detect 0x1000 bootloader.bin 0x8000 partitions.bin 0x10000 firmware.bin```

+Get the bootloader here: [Arduino ESP32 bootloader](https://github.com/espressif/arduino-esp32/tree/master/tools/sdk/bin) The default bootloader is [bootloader_dio_40m.bin](https://github.com/espressif/arduino-esp32/raw/master/tools/sdk/bin/bootloader_dio_40m.bin)
