Bootcmd_usb0 not defined

[zjq]

Hello,

I am trying to reload the Toradex Easy Installer from USB stick, but when I tried to run bootcmd_usb0 in U-boot, I got the error message:

Verdin AM62 # run bootcmd_usb0

Error: “bootcmd_usb0” not defined

Could you please advise what should be the command for bootcmd_usb0?

I have Verdin AM62 on Ivy Plus Carrier board.

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.

The recommended and only fully supported method to reload the Toradex Easy Installer is by using Recovery Mode and OTG . . An alternative methods, not officially supported by Toradex. Tough in some cases it possible to load the Toradex Easy installer from an External Media (SD Card/USB Stick) this method required some prerequisites (like fully functional U_Boot with Distro boot support) which may not always be available.
