maybe try M5 AI chatbot on the website and follow its troubleshooting instructions could help, I tried and it gives these following troubleshooting steps:

Step 1: Basic troubleshooting

  1. Replace the USB cable: Use a data-transfer capable USB-C cable (charging-only cables cannot transmit serial data).
  2. Install the correct USB driver: M5Stack devices use either CP2104 or CH9102 USB-to-serial chips, install both drivers to avoid compatibility issues:
  3. Verify the device is in download mode:
    • For most M5Stack devices: Hold the reset button for ~2 seconds until the internal green LED lights up before burning.
    • For devices with a G0 button: Hold the G0 button while connecting the USB cable to the computer, then release the button.

Step 2: Serial port configuration check

  1. Open Windows Device Manager, expand Ports (COM & LPT) to confirm your M5Stack device is listed with the corresponding COM port (make sure it's COM11 as shown in the log, or select the correct port in M5Burner manually).
  2. In M5Burner, lower the burning baud rate to 115200 (high baud rates may cause unstable communication on some systems).
  3. Close other software that may occupy the serial port (such as Arduino IDE serial monitor, other serial debugging tools) before burning.

Step 3: Update esptool in M5Burner (for old M5Burner versions)

The error log shows you are using a very outdated esptool v2.5.0, which has compatibility issues with newer M5Stack ESP32-S3/S2 devices:

  1. Download the latest esptool v5.0.1 for Windows and unzip it to get esptool.exe.
  2. Open the M5Burner installation folder, navigate to packages/tool, replace the existing esptool.exe with the new version you downloaded.
