ESP32FlashWriter

An easy to use GUI that you can use to connect with your ESP32 devices and update its firmware.

  1. Simply plug in your device(s) via USB/Serial cable to your Linux OS computer and select your device port and the baud (default baud is 11520 bps). The port selection will trigger the connection. In the event your ESP32 becomes unplugged after it is connected, the GUI will notify you to replug and reselect your device port.

  2. To update your ESP32 firmware, simply click on the folder icon to select your new firmware, decide if you want to erase the entire flash or not, and then click WRITE to update your ESP32 firmware.

  3. You can use your keyboard Tab key to toggle between the fields in the GUI. Pressing the Return key will select the field. To exit the selected field, press the Esc key. Scrolling within the Port and Baud fields can be done by pressing the and arrow keys.

This GUI script is a work-in-progress. I have used it to write firmware to a ESP32D0WDQ6(revision1) chip in a ESP32 DEVKITV1 board. Appreciate if you can share with me the type of ESP32 chip or board that you were able to use ESP32FlashWriter to connect with, and/or write firmware on. Thank you.

You can’t perform that action at this time.
