loss connection to target when deploy project to rpi 4

[Kilwa]

Every time i try to deploy a project to raspberry pi 4 i have got a message about losing connection to target. here's a screenshot

i have tried to many things. like 

sudo schroot -c labview -d /usr/lib -- ln -s liblinxdevice_rpi2.so liblinxdevice.so

but none of theme works.

can any idea please? 

thanks in advance.

What version of LabVIEW and LINX are you using?

What version of Raspberry Pi OS are you using?

Does this happen both when connecting over a wired Ethernet connection and WiFi?

[Kilwa]

 version of LabVIEW 2020 community

version of Raspberry Pi OS : 10.7

this happen when connecting over wifi and Ethernet

Well it will be tricky to diagnose a WiFi issue as your setup could cause the issue.

Try a wired connection and does it work?

I post this before your update.  Well if the something happens over wired that is a different story.

the same thing does happens with wired connection!

i doubt about setting up Raspberry Pi with LabVIEW? 

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 lvrt20-schroot -y

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

 did i forget anything?!

Why are you setting it up manually?  Why not use the tool built into LINX and LabVIEW 2020?
