Usage Guidelines
When you enter the boot command without any arguments, the device attempts to automatically boot the
system by using the information in the BOOT environment variable, if any.
If you supply an image name for the file-url variable, the boot command attempts to boot the specified image.
When you specify boot loader boot command options, they are executed immediately and apply only to the
current boot loader session.
These settings are not saved for the next boot operation.
Filenames and directory names are case sensitive.
Examples
This example shows how to boot the device using the new-image.bin image:
