Installing TFTP server
Contents
Background Information
Trivial File Transfer Protocal or TFTP is used to transfer files from machine to machine with less overhead that our protocols. For more information about TFTP see the following page: [ http://en.wikipedia.org/wiki/Trivial_File_Transfer_Protocol ]
Nearly all of the EMAC ARM based systems require a TFTP server to transfer the Linux kernel and file system to the board from a host PC. The boot loader will connect to the server and retrieve specific files and relocate them to SDRAM for programming on the target's flash.
Installing a TFTP server on Ubuntu
There are several TFTP server alternatives in Ubuntu. The tftpd or tftpd-hpa packages are recommend for install.
Installing tftpd
To install the tftpd package run the following:
sudo apt-get install tftpd
To configure the the TFTP server, create /etc/xinetd.d/tftp
with the following contents:
service tftp { protocol = udp port = 69 socket_type = dgram wait = yes user = nobody server = /usr/sbin/in.tftpd server_args = /tftpboot disable = no }
Run the following to create the TFTP server's base directory:
sudo mkdir /tftpboot sudo chmod -R 777 tftpboot sudo chown -R nobody /tftpboot
Once the configuration is complete the xinetd start should be restarted to enable the server:
sudo /etc/init.d/xinetd restart
The TFTP server is then ready to send/recieve files from /tftpboot.
Notes that the used directory can be changed to your needs by editing the server_args variable in /etc/xinet.d/tftp file. |
Installing a TFTP server on Windows
For Window's based systems, EMAC recommends the Tftpd32 server. The installation procedure is typical and should be self explanatory.
