The following are some common issues that have been seen in the past.
In the rare instance that things get really bad, you may need to reflash your jetson. Should this be the case, the next few sections will guide you through this proccess.
1 - System Setup
Your Jetson should already have the operating system installed and configured for you. These instructions are provided in case you need to wipe your Jetson and start fresh.
Initial Setup
Note
If using a serial connection, all the navigation here on out will be done via your keyboard. Use the arrow keys and Tab to move the cursor, and Enter to confirm options.
Select “Ok”
Scroll through agreement and select “Ok”
Select your language
Select your country
Select your timezone
Allow clock to be set to UTC
Creating your account
Enter a name, such as your school’s name
Choose a username, such as “avr”
Choose a password
Retype your chosen password
When asked about resizing the partition, leave the default.
Network Configuration
Setting up a network connection is not needed at this time. To bypass this, select “dummy0” and let the autoconfiguration fail.
Go ahead and select “Do not configure the network at this time”.
Final Setup
Select an appropriate hostname for your Jetson. “drone” is a good choice.
Choose the “MAXN” power mode.
Let the installation finish. Once it’s done, reboot your Jetson.
2 - Installing VMC Software
Internet
In order to install the AVR software, your Jetson needs to have an internet connection. The easiest way by far is if you have ethernet available. If so, just plug an ethernet cable into your Jetson and you should be good to go.
If you don’t have ethernet, you can use a WiFi connection. First, you can list the available networks with:
nmcli device wifi list
Example:
WiFi network list
Hit q to exit the list.
If the Jetson is already connected to a WiFi network, you can disconnect it with:
sudo nmcli device disconnect wlan0
To connect to a WiFi network, run:
# with a password
sudo nmcli device wifi connect <network name> password <password>
# without a password
sudo nmcli device wifi connect <network name>
such as:
sudo nmcli device wifi connect "WI do drones FI" password "Flying_Is_Fun"
If your network name or password has a space or other special characters, you’ll need to wrap it in quotes as shown above.
Install
git clone --recurse-submodules https://github.com/bellflight/AVR-2022 ~/AVR-2022
cd ~/AVR-2022/VMC/scripts
chmod +x setup.py
./setup.py
This clones the software repo, changes directory into the repo you just cloned, makes the setup script executable, and then executes the setup script.
Setup script starting
This setup script will automatically install and configure everything needed on your Jetson to get it ready for competition. This script does do operating system updates, so depending on your internet connection, it may take a while to run.
At the end of the setup script, it will perform a few self-tests to make sure everything is configured properly.
Self-tests passing
Once this is done, please restart your Jetson. Some system settings were changed that require a reboot to take effect.
Reboot prompt
After this, you should be ok to continue on with the setup per the updating per Updating VMC Software
