Beginner's tutorial step 6

Now that you have built and "installed" the Armadeus SDK (based on Buildroot), we will show you how to transfer the generated images to your board.

At this stage, you should have something looking like that (IP addresses may change):

Serial Terminal configuration

You will need a Serial terminal emulator to communicate with U-Boot/Linux console. You can choose between:

• Kermit
• Minicom
• GTKTerm
• Screen
• Microcom
• Nanocom

We suggest you to use Kermit as Terminal emulator. Minicom was sadly reported to have problems when communicating with U-Boot (ZModem data transfer). If you just need a simple serial console and not to transfer data through the serial link, then GTKTerm is the perfect choice ! (gtkterm package in Ubuntu)

Note: Your terminal should now be configured with: 115200 bauds 8N1 parameters

TFTP server

In order to send your image files (U-Boot, Linux, rootfs or FPGA's firmware) at higher speed (than serial port) to your Armadeus board, you can use the Ethernet link and a TFTP server. Once the server configured, the files located in the server shared directory (/tftpboot by default) will be accessible from the U-Boot/Linux TFTP clients.

TFTP server installation

Install packages

* On *Ubuntu / Debian: $ sudo apt-get install tftpd xinetd or use your preferred graphical package manager

* On Fedora: $ rpm -q tftpd xinetd

* On OpenSUSE 11.3: sudo zypper install tftp yast2-tftp-server sudo yast2 tftp-server Choose Enable to start the TFTP server. It might be required to open the TFTP port in your firewall. For more details see: YaST TFTP Server on OpenSUSE site

Create server's directory

• Then create the directory (/tftpboot/) that will contain all the files that the server will export:

$ sudo mkdir /tftpboot
$ sudo chmod 777 /tftpboot

Server configuration

• As root user edit or create the /etc/xinetd.d/tftp configuration file and modify/add it the following lines:

# default: off
# description: The tftp server serves files using the trivial file transfer
#       protocol.  The tftp protocol is often used to boot diskless
#       workstations, download configuration files to network-aware printers,
#       and to start the installation process for some operating systems.
service tftp
{
       socket_type             = dgram
       protocol                = udp
       wait                    = yes
       user                    = root
       server                  = /usr/sbin/in.tftpd
       server_args             = -s /tftpboot
#       disable                 = yes
}

• Restart xinetd service:

$ sudo killall -HUP xinetd
