U-Boot Commands
7.1 Overview
The SAM1411 uses U-Boot version 2010.06 to initialize Linux on the PPC.
When power is applied to the SAM1411, U-Boot initializes the RAM and downloads the kernel
image to memory. It also provides support for Ethernet protocols like TFTP, that makes it
possible to download images from network servers. Before U-Boot starts decompressing the
Linux kernel, you have a few seconds to pause the process and execute some of the commands
that U-Boot provides to check or modify the system.
