Install Linux OS on development host and build cross compiler development environment. Do
the main job on Windows PC. Use JTAG for building boot image. As processing speed of JTAG
is very slow, download executable images through Ethernet network once boot loader is under
operation on the development board. BOOTP and TFTP are used in this process. BOOTP is
used in order to get an IP on the development host and TFTP is program used in order to
download real image from it. Using terminal emulator (HyperTerminal, etc), these programs
provide the environment to see message from boot loader on device or execute command. And
they provide console windows after Linux system starts. NFS allows embedded device, which
does not have large-capacity memory, to share files on the host after Linux kernel starts on the
device. Samba allows Windows client to share files on Linux machine that is the development
host.
