DEVELOPMENT
5.1 Host Network Preparation
For various tasks involving a network in the Bootloader, some host services are required to be set up. On the
development host, a TFTP, NFS and DHCP server must be installed and congured. The following tools
will be needed to boot via Ethernet:
host:~$ sudo apt install tftpd-hpa nfs-kernel-server kea
5.1.1 TFTP Server Setup
• First, create a directory to store the TFTP les:
host:~$ sudo mkdir /srv/tftp
• Then copy your BSP image les to this directory and make sure other users have read access to all the
les in the tftp directory, otherwise they are not accessible from the target.
host:~$ sudo chmod -R o+r /srv/tftp
• You also need to congure a static IP address for the appropriate interface. The default IP address
of the PHYTEC evaluation boards is 192.168.3.11. Setting a host address 192.168.3.10 with netmask
255.255.255.0 is a good choice.
host:~$ ip addr show <network-interface>
Replace <network-interface> with the network interface you congured and want to connect the board
to. You can show all network interfaces by not specifying a network interface.
• The message you receive should contain this:
inet 192.168.3.10/24 brd 192.168.3.255
• Create or edit the /etc/default/tftpd-hpa le:
# /etc/default/tftpd-hpa
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/srv/tftp"
TFTP_ADDRESS=":69"
TFTP_OPTIONS="-s -c"
• Set TFTP_DIRECTORY to your TFTP server root directory
