<p><b>Neue Seite</b></p><div>TFTP server is used for transferring files onto embedded devices. For example, most boot loaders support loading a Linux kernel image via TFTP at boot. This is very useful during development.<br />
<br />
== Install a TFTP server ==<br />
<br />
The following is tested on Ubuntu 9.04 and 10.04.<br />
<br />
*Install the package '''tftpd-hpa'''.<br />
<br />
*Configuration file '''/etc/default/tftpd-hpa''':<br />
RUN_DAEMON="yes"<br />
OPTIONS="-c -l -s /tftpboot"<br />
<br />
*Configuration file for newer versions of ''tftpd-hpa'' (this example is from a Ubuntu 10.04.1 installation):<br />
TFTP_USERNAME="tftp"<br />
TFTP_DIRECTORY="/tftpboot"<br />
TFTP_ADDRESS="0.0.0.0:69"<br />
TFTP_OPTIONS="-c -s"<br />
<br />
The TFTP server’s root directory is /tftpboot/ in this example. Place files there that should be accessible via TFTP. Of course you are allowed to create subdirectories. If you have problems with downloading a file, try changing the permissions of the /tftpboot directory and/or files to 0777:<br />
chmod 777 /tftpboot<br />
<br />
== Load a file with U-Boot ==<br />
<br />
In U-Boot, to load the file "uImage" to address 0x1000000, type the command:<br />
tftp 0x1000000 uImage<br />
''Note: This example is valid for Blackfin U-Boot bootloaders. (Load address may differ on other platforms.)''<br />
<br />
== Load a file with Redboot ==<br />
<br />
In Redboot, to load the file "zImage" to address 0x100000, type the command:<br />
load -r -b 0x100000 zImage<br />
''Note: This example is valid for SBC-i.MX51.''<br />
