Hello,

The error message “bootcmd_usb0 not defined” indicates that your Verdin AM62 module’s U-Boot environment does not have a predefined command for booting from a USB stick. This is common if the environment variables for USB booting are not set by default.

To set up USB booting, you can manually define the necessary U-Boot environment variables. Here’s how you can do it:

  1. Access the U-Boot Console:

    • Power on your module and interrupt the boot process by pressing any key to enter the U-Boot console.

  2. Check Current Environment Variables:

    • Use the command printenv to display all current environment variables. Look for any related to USB booting.

  3. Define the USB Boot Command:

    • If bootcmd_usb0 is not defined, you can create it. A typical command might look like this:
      setenv bootcmd_usb0 'usb start; fatload usb 0:1 ${loadaddr} /boot/uImage; bootm ${loadaddr}'
saveenv
    • This command initializes the USB interface, loads the kernel image from the first partition of the USB stick, and boots it.

  4. Test the New Command:

    • After setting the environment variable, test it by running run bootcmd_usb0 in the U-Boot console.

  5. Adjust as Necessary:

    • Depending on your setup, you might need to adjust the paths or filenames in the command. Ensure your USB stick is formatted correctly and contains the necessary boot files.

If you encounter further issues, double-check the USB stick’s contents and formatting, and ensure the USB port on the carrier board is functioning properly.

I hope this helps you get the Toradex Easy Installer running from your USB stick.
