RS232 Terminal configuration
You will need a RS232 terminal emulator to communicate with U-Boot/Linux console. You can choose between:
- Kermit
- Minicom
- GtkTerm
We suggest you to use Kermit as Terminal emulator for RS232 connection. 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 RS232, then GTKTerm is the perfect choice ! (package gtkterm in Ubuntu)
TFTP server
In order to send your image files (U-Boot, Linux, rootfs or FPGA's firmware) at higher speed to your Armadeus board, you can use the Ethernet link and a TFTP server. Once the server started, the files located in the server shared directory (/tftpboot by default) will be accessible from the U-Boot/Linux TFTP clients.
TFTP server installation
- On *Ubuntu / Debian:
$ sudo apt-get install tftpd xinetd
or use Synaptic
- On Fedora:
# rpm -q tftpd xinetd
- Then create the directory that will contain all the files that the server will export (you have to be root to do that):
$ sudo mkdir /tftpboot $ sudo chmod 777 /tftpboot
Server configuration
- Edit or create the configuration file /etc/xinetd.d/tftp 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
- Put some files in /tftpboot
- To test it from U-Boot (if you already have the correct IP addresses, otherwise continue with Setup Basics here):
