To get started with the DAO package on Ubuntu, first set up the root file system for octeon platform, then follow the step-by-step instructions for installing and configuring the DAO package, ensuring a smooth and efficient setup process.

2.2.1. Preparing ubuntu root file system

To access the Ubuntu root file system from the Octeon platform, prepare the file system first and then enable Network File Sharing (NFS), thereby facilitating seamless cross-platform file access and management.

# mkdir ubuntu_base
# cd ubuntu_base
# wget https://cdimage.ubuntu.com/ubuntu-base/releases/22.04/release/ubuntu-base-22.04-base-arm64.tar.gz
# sudo tar xvfp ubuntu-base-22.04-base-arm64.tar.gz

2.2.2. Setting up the ubuntu environment

Once the octeon board is UP with above ubuntu rootfs

  • Setting up the environment by updating and upgrading ubuntu distro.

# echo "185.125.190.36 ports.ubuntu.com" >> /etc/hosts
# apt-get update
# apt-get upgrade

  • Installing required packages:

# apt-get -y install initramfs-tools init dbus iproute2 sudo nano openssh-server netbase
# apt-get -y install libnfs-utils nfs-common iputils-ping curl gpg
# apt-get -y install apt-utils dialog locales vim
# locale-gen en_US.UTF-8

  • Set Root password

# passwd

  • Enable root login by updating sshd_config

# vim /etc/ssh/sshd_config
Update PermitRootLogin to yes

  • Reboot the board

  • Resolving DNS

# vim /etc/systemd/resolved.conf

Above file should contain following stuff
--
[Resolve]
DNS=1.1.1.1 8.8.8.8
--

# systemctl restart systemd-resolved

# hostnamectl hostname <hostname>

2.2.3. Update ubuntu repository to download dao packages

# curl -fsSL https://www.marvell.com/public/repo/octeon/dao/cn10k/ubuntu/v2204/release/dao.gpg | sudo gpg --dearmor -o /etc/apt/keyrings/dao.gpg
# curl -SsL -o /etc/apt/sources.list.d/dao.list https://www.marvell.com/public/repo/octeon/dao/cn10k/ubuntu/v2204/release/dao.list
# sudo chmod 644 /etc/apt/sources.list.d/dao.list
# sudo chmod 644 /etc/apt/keyrings/dao.gpg
# apt-get update
