It's time for deployment. The kernel data needs to be transferred to the target. This can be done with JTAG tools or in-circuit emulators. A more convenient way would be to have a good working boot loader on the target. The example uses TFTP (trivial file transfer protocol), a UDP protocol which will extract the image from our host system by Ethernet. The host system you are using, Windows or Linux, will need a TFTP server running. The image should be placed in the tftpboot directory. Having done that, the boot loader can issue a command which would take that image and put it into memory, the one million hex location in the example here. The boot loader is smart enough to realize that this is an elf image, and inside that elf image will be the layout of the final target system. A bootelf command tells it to inspect the image, place everything, and execute it.
