LINX on the Raspberry Pi 2, 3 and 4 running Raspbian Buster

Question

Hi everyone,
LINX can be installed on the Raspberry Pi 4.

The LINX 3.0 Target Manual Install Process (https://www.labviewmakerhub.com/doku.php?id=learn:libraries:linx:misc:target-manual-install) did not work due to changes in the latest version of Raspbian.

Here is the procedure that I used to install LINX. The procedure also works on the Raspberry Pi 2B, Pi 3A+, Pi 3B and Pi 3B+ running Raspbian Buster.

1. Setup the Raspberry Pi using the latest Raspbian Buster Image.
2. Change the default password for the Pi account on the Raspberry Pi.
3. Setup a WiFi or Ethernet connection from the Raspberry Pi to your router.
4. Enable SSH on the Raspberry Pi.
5. SSH into the Raspberry Pi or open a terminal window on the Raspberry Pi desktop.
6. Check that the Raspberry Pi can access the Internet by entering the command

ping -c 4 raspberrypi.org

7. Enter the commands shown in bold below. 
Note: The text may wrap due to the web browser window size. I recommend copying the text into a text editor to see the original formatting. The commands are in the attached file linx_install_commands.txt

# Enable i2c and spi
sudo raspi-config nonint do_i2c 0
sudo raspi-config nonint do_spi 0
# Update Raspbian
sudo apt-get update
sudo apt-get dist-upgrade -y
# Install LINX
sudo sh -c 'echo "deb [trusted=yes] http://feeds.labviewmakerhub.com/debian/ binary/" >> /etc/apt/sources.list'
sudo apt-get update
sudo apt-get install -y lvrt-schroot
# Move the nisysserver.service and labview.service files to the systemctl folder
sudo mv /etc/systemd/system/multi-user.target.wants/nisysserver.service /lib/systemd/system
sudo mv /etc/systemd/system/multi-user.target.wants/labview.service /lib/systemd/system
# link liblinxdevice.so to the Raspberry PI device driver file liblinxdevice_rpi2.so
sudo schroot -c labview -d /usr/lib -- ln -s  liblinxdevice_rpi2.so liblinxdevice.so
# Enable the nisysserver.service and labview.service to start on boot
sudo systemctl enable nisysserver.service
sudo systemctl enable labview.service
# Start the nisysserver.service and labview.service
sudo systemctl start nisysserver.service
sudo systemctl start labview.service

You should now be able to connect to the Raspberry Pi from the LabVIEW Project Explorer.

Cheers,
Andy.

Hey just found your guide as i was having the exact same problem on RPi 4. Thank you so much! If i wanted to run a Project using AD2 on Boot, do i need to enable digilent runtime on boot as well?

I have a Raspberry Pi 4 B running Rasbian BUSTER.

I attempted this procedure, but it failed when I entered the following commands:

sudo sh -c 'echo "deb [trusted=yes] http://feeds.labviewmakerhub.com/debian/ binary/" >> /etc/apt/sources.list'
sudo apt-get update

the following errors occur:

E: Conflicting values set for option Trusted regarding source http://feeds.labviewmakerhub.com/debian/ binary/
E: The list of sources could not be read.
 

I apologize for not being very familiar with Linux, but it seems that the issue was that it could not find the source list?

Any help would be appreciated.
