...
Second, set DIP-SW (boot-select switch) to “boot from USB”. For example, if you are using SP7021 Ev Board, please set DIP-SW to OFF-OFF-OFF-OFF-ON-OFF (1-1-1-1-0-1) for booting from USB flash drive. Refer to picture below, DIP-SW is set to OFF-OFF-OFF-OFF-ON-OFF.
...
Refer to Selection of boot devices of SP7021 (Plus1) for details of boot selection of SP7021.
...
Now, you are ready to boot SP7021 Linux from SPI-NOR flash. Turn on power of SP7021 board to boot system.
Refer to log (from u-boot to kernel) of booting from SPI-NOR (JFFS2):
