This article talks about the commands and steps needed to set up a TFTP server in Ubuntu Linux.

TFTP is a simple file transfer system widely used in embedded development. It will also be needed when dealing with PetaLinux. First, we will have to install tftp-hpa as well as tftpd-hpa. The command is as follows:
sudo apt-get install tftp-hpa tftpd-hpa
TFTP requires a folder in order to store files. We can create a folder named tftp in the root directory, which would have the directory of /tftpboot. This is because PetaLinux defaults to this directory, thus making our lives easier in the future when everything is installed. The commands are as follows:
sudo mkdir -p /tftpboot
sudo chmod 777 /tftpboot
Note how we used 777 in the second command, which gives it permissions to read, write, and execute for all users; we want to help set up the permissions for the tftpboot folder for future usage.
Finally, we will go on to configure tftp. We can create and open /etc/default/tftpd-hpa by using the following command:
vi /etc/default/tftpd-hpa
We will proceed to fill it out as follows:
# /etc/default/tftpd-hpa TFTP_USERNAME=“tftp” TFTP_DIRECTORY=“/tftpboot” TFTP_ADDRESS=“/tftpboot” TFTP_OPTIONS=“-l -c -s”
Finally, we will enter the following command to restart the tftp server, and thus finish building it.
sudo apt-get install nfs-kernel-server
