The Flash Download Tool Flashing in conjunction with Espressif’s official flashing accessories can be used for automated deployment and mass production flashing.

• Flashing baseboard (one module flashed at a time)

• Fixture (4 modules flashed at once)

Flashing process using Espressif’s official fixture

1. Relay power supply

   The adapter is connected as shown in the figure to power the relay; the relay serves as a delay to ensure that the module is powered on after the fixture handle is pressed down stably.

   

2. The fixture baseboard serial port is connected to the computer through the HUB

   Use a USB cable to connect the 4 mini USBs on the two baseboards under the fixture box to the HUB. The HUB needs to be independently powered to ensure that each serial port provides sufficient power to the module; then connect the HUB to the computer. (The fixture can be connected to the computer for single serial port download)

   

3. Download

   Select the firmware to be downloaded, set the serial port; place the modules in the four positions on the fixture, press down the handle, and click START to start downloading. For detailed steps, refer to: Using the Flash download tool Flashing Process
