%SECTION0{NAME=UserInterface}% User Interface U-Boot uses a simple command line interface (CLI), usually over a serial console port. Two different command interpreters are available: * simple CLI * Bourne compatible shell (HUSH shell from Busybox) Configuration parameters and commands / command sequences (scripts !) can be stored in "environment variables" which can be saved to non-volatile storage (flash, EEPROM, NVRAM, etc.)
