Ansible Configuration Scripts

This is meant to be ran on a fresh image and will setup all necessary packages and configurations to tie it into the SpectrumX platform.

Usage

• Create /opt/radiohound
• Copy the ssh key to /opt/radiohound/.ssh/id_rsa. See Randy for more info.
• Copy .env.docker to /opt/radiohound/.ssh/.env.docker. See Randy for more info.
• Clone the following repo to /opt/ansible

GIT_SSH_COMMAND='ssh -i /opt/radiohound/.ssh/id_rsa -o IdentitiesOnly=yes' git clone [email protected]:spectrumx/ansible.git

• Run the following:

python3 /opt/ansible/run.py

What's managed?

• Icarus, the application that manages connection to the SpectrumX sensing platform
• Ensures Ansible runs nightly
• Installs dependency packages (Radioconda/GNURadio, Docker, Mosquitto)

To build Jetson image with A608 Carrier Board

Physical setup:

• Ubuntu 2204 machine
• Jetson booted in recovery mode, once booted remove jumper
• Ubuntu machine connected (via USB-A) to Jetson (USB-C)
• NVME drive in a USB-C drive chassis, connected with USB-A adapter to the Jetson
• Confirm Jetson is connected by running lsusb and looking for Nvidia device

Software setup on Ubuntu machine:

sudo apt install unzip bzip2
sudo tar xpf jetson_linux_r36.3.0_aarch64.tbz2
sudo tar xpf tegra_linux_sample-root-filesystem_r36.3.0_aarch64.tbz2 -C Linux_for_Tegra/rootfs/

cd ..
unzip 608_jp60.zip
sudo cp -r ./608_jp60/Linux_for_Tegra/* ./Linux_for_Tegra/

Add files to rootfs before building the image

cd /home/rherban
git clone [email protected]:spectrumx/id_rsa.git

cd Linux_for_Tegra/rootfs
mkdir opt/radiohound
cp -r /home/rherban/ssh opt/radiohound/.ssh    # MUST GET KEYS FROM RANDY
chmod 600 opt/radiohound/.ssh/id_rsa

cp /home/rherban/ansible/files/setup_ansible.service etc/systemd/system/
cp /home/rherban/ansible/run.py root/setup_ansible.py
chmod 755 root/setup_ansible.py
ln -s etc/systemd/system/setup_ansible.service etc/systemd/system/multi-user.target.wants/setup_ansible.service

cd ..
sudo ./tools/l4t_create_default_user.sh --accept-license -u mep -p <REDACTED> 


cd ..

Run this command to build image and flash the Jetson

TODO:

• Add separate /data partition
• Fix Icarus' virtualenv path
• Add SDS pip package

Additional tips

• Add ssh key for git commands: export GIT_SSH_COMMAND="ssh -i /opt/radiohound/.ssh/id_rsa"
