Hello! Thank you for providing detailed information about your process and the error messages.

Your board is detecting the USB host controller and at least one device on the bus, but it is not recognizing your USB stick as a storage device. Here are some recommended troubleshooting steps for this scenario:

  1. USB Stick Compatibility
    Some USB devices are not fully compatible with the U-Boot USB stack and may fail to enumerate correctly (reference). Please try:

    • A different USB stick, preferably from another manufacturer.
    • Using a USB 2.0 stick instead of USB 3.0, as sometimes there are better results with simpler devices.
  2. Power Supply
    Ensure your board’s USB port provides enough power for the USB stick. Some sticks require more current, and insufficient power can cause detection failures (reference).

  3. USB Stick Preparation
    Double-check that your USB stick is:

    • Formatted as FAT32.
    • The TEZI files are unzipped and present in the root directory, not within a folder.
    • If you are following the external media loading method, make sure that you have renamed boot-tezi.scr to boot.scr (reference).
  4. Unsupported Method Caveat
    The method you’re using (external media loading with a USB stick) is not officially supported by Toradex and depends on “Distro Boot,” which does not always work reliably across all U-Boot versions (reference).

  5. Alternative - Official Method
    For the most reliable experience, it is strongly recommended to use the USB OTG recovery method.

    • Put your module in recovery mode.
    • Use the recovery script from the TEZI package on your host to load the installer over the USB OTG interface.
    • This method is supported and more robust for loading TEZI (reference).

Summary of recommended actions:

  • Test with a different, FAT32-formatted USB stick.
  • Check your power supply and USB port.
  • Ensure correct file preparation and naming.
  • If possible, use the USB OTG recovery method for best results.

Let me know if you need step-by-step instructions for the official OTG recovery method or further troubleshooting.
