+ 4. Release the **RST** button
+ 5. Release the **BOOT** button (If there is no **BOOT** button, disconnect IO0 from GND.)
+ 6. Upload sketch

+
+### Use command line
+
+
+If system asks about install Developer Tools, do it.
+
+```
+python3 -m pip install --upgrade pip
+python3 -m pip install esptool
+```
+
+In order to launch esptool.py, exec directly with this:
+
+```
+python3 -m esptool
+```
+
+For ESP32 use the following command to write
+
+```
+esptool --chip esp32  --baud 921600 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_freq 80m 0x0 firmware.bin
