Flash with esptool (Ubuntu)

• Install esptool:

  git clone [email protected]:espressif/esptool.git
  cd esptool/

• Download the newest release.
• Connect a microUSB cable directly to the ESP32 (the USB-C port at the case is only for charging the battery)
• Detect the correct port:

  ls /dev/ttyUSB*

• Run the flash command:

  ./esptool.py \
    --chip esp32 \
    --port /dev/ttyUSB0 \
    --baud 921600 \
    --before default_reset \
    --after hard_reset write_flash \
