Restoring Bootloader

The first step in restoring the boot loader is the ability to write to the boot loader.

  1. Attach power to the ESP32-S T-Display microcontroller.
  2. Press and hold the "Boot" (left) button.
  3. While holding down the "Boot" button, press and release the "Reset" button.
  4. Now release the "Boot" button.
  5. Launch Adruino IDE
  6. Select Tools -> Board -> esp32 -> ESP32S3 DEV MODULE
  7. Select Tools -> Port -> cu.usbmodem14601
  8. Select Tools -> Programmer -> esptool
  9. Select Tools -> Burn Bootloader

Loading Code onto ESP32-S T-Display Microcontroller

The first step is downloading a program built for the esp32-s t-display microcontroller.

  1. Launch Adruino IDE
  2. Load the code into the Adruino IDE
  3. Select Tools -> Board -> esp32 -> ESP32S3 DEV MODULE.
  4. Select Tools -> Port -> cu.usbmodem14601 (Note, If you find the Port is toggling between not being accessible and being accessible, try the following: Hold the "Boot" button then, press and release the "Reset" button and finally release the "Boot" button.
  5. Select Sketch -> Verify/Compile
  6. Select Sketch -> Upload
  7. Note: Sometimes after a load it's necessary to press the reset button to begin the execution of the new code.
