TFTP Netbooting
Setting up a TFTP server(Host PC)
Install the following packages on your host PC
$ sudo apt install xinetd tftpd tftp
Create file “/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
}
Create directory `/tftpboot/' (this matches the `server-args' above) and set its permissions:
$ sudo mkdir /tftpboot/ $ sudo chmod -R 777 /tftpboot/ $ sudo chown -R nobody /tftpboot/
Restart the `xinetd' service:
$ sudo service xinetd restart
Test the server by creating a simple `test' file in `/tftpboot/': <coe host> $ cd /tftpboot/ $ echo “this is a test” > test </code>
Get the IP address of your host PC via “ip addr”, then from another system:
$ tftp <host_pc_ip_address> $ tftp> get test $ Sent 159 bytes in 0.0 seconds $ tftp> quit $ $ cat test $ this is a test
Copy your kernel and dtb binary into the “/tftpboot” folder.
