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.

Configure boot.ini file.

Comment out the changes to boot from primary partition /media/boot/boot.ini file.

# fatload mmc 0:1 ${initrd_loadaddr} uInitrd
# fatload mmc 0:1 ${loadaddr} Image
# fatload mmc 0:1 ${dtb_loadaddr} meson64_odroidc2.dtb

And Replace these with following

# Booting via tftp server configuration
# setting up the tftp parameters
setenv tftpImage Image
setenv tftpFdtfile meson64_odroidc2.dtb
setenv tftpuInit uInitrd
setenv ipaddr 192.168.0.3         # client ip address
setenv serverip 192.168.0.2 	    # server ip address
