Then you should be able to execute the bootscript from the environment which loads the system from USB like run bootcmd_usb0 where the 'run' command executes command list from environment variable and 'bootcmd_usb0' is a command list predefined in the default environment. Random (unofficial) document that lists u-boot commands is here: https://www.digi.com/resources/documentation/digidocs/PDFs/90000852.pdf Note that the availability of commands depents on compiled-in features. There might be an official u-boot manual but it is notoriously hard to find. In case of problems you might want to use the usb command to determine if your storage device has been detected (or if you happen to have more than one in which case you may need to specify number other than 0 in the above).
