Transfers files to and from a remote computer running the TFTP service.
TFTP [-i] host [GET | PUT] source [destination]
-i Specifies binary image transfer mode (also called octet). In binary image mode the file is moved literally, byte by byte. Use this mode when transferring binary files. host Specifies the local or remote host. GET Transfers the file destination on the remote host to the file source on the local host. PUT Transfers the file source on the local host to the file destination on the remote host. source Specifies the file to transfer. destination Specifies where to transfer the file.
Linuxでは、つぎのようなコマンドが使えます。

使い方は簡単なのですが、セットアップには、いくつかのピットフォール（落とし穴）があり、
そう簡単には動きませんでした (^_^;)
まず、Raspberry PiにTFTPサーバーをインストールします。
つぎのコマンドでインストールできます。
sudo apt-get install tftpd-hpa
ところが、なんということでしょう～
結果は、つぎのように、TFTPサーバーはエラーで起動しませんでした！
