LabVIEW FPGA Compile Worker Systemd Service not working

friml · ‎05-06-2022

Hi, I am trying to make LabVIEW FPGA Compile Worker Systemd Service work. I have installed, tested, and working NI-LVFPGA2020-LinuxVivado, Xilinx Vivado 2019.1 compilation toolkit (64-bit) on centos 7.9.2009. Launching compile worker after every restart manually by clicking into GUI is not an option for me, so I decided to try systemd service according to Official manual.

I came up with an installation script solving some typos present in the installation manual

#!/bin/bash
bold=$(tput bold)
normal=$(tput sgr0)
if [ "$EUID" -ne 0 ]
  then echo "${bold}Please run as root${normal}"
  exit
fi

echo "${bold}Installing prerequisities${normal}"
yum install -y Xvfb mono-core

echo "${bold}Copying required files${normal}"
cp start_nifpgacompileworker.sh /usr/local/natinst/nifpgacompileworker/
cp nifpgaworker.service /etc/systemd/system/

echo "${bold}Setting privileges to copied files${normal}"
chmod 664 /etc/systemd/system/nifpgaworker.service
chmod 774 /usr/local/natinst/nifpgacompileworker/start_nifpgacompileworker.sh

echo "${bold}Running CompileWorkerSetup${normal}"
cd /usr/local/natinst/nifpgacompileworker
sh cw_wrapper.sh mono CompileWorker.exe

kill -9 $(pgrep -f CompileWorker)

echo "${bold}Setting up systemd${normal}"
systemctl daemon-reload
systemctl enable nifpgaworker.service
systemctl start nifpgaworker.service

echo "${bold}Status of nifpgaworker.service${normal}"
systemctl status -l nifpgaworker.service | grep "Active:"
sleep 1s
echo "   $(systemctl status -l nifpgaworker.service | grep -o 'Connected.*"')"

echo "${bold}For more information use${normal} 'systemctl status nifpgaworker.service'"

Everything seems to work smoothly according to systemd logs, the worker is successfully connected to the compilation server, registering Vivado 2019.1.

$ systemctl status -l nifpgaworker.service

Compilation results in error while trying to synthesize using vivado

It seems that some HOME environment variable is missing according to Xilings log

I cannot provide more details from the compilation server, as an unobtainable Silverlight is required.

Summary: FPGA Compile Worker ran by systemd fails when synthesizing using Vivado. When the same worker is launched in GUI, everything works fine.

Any idea how to solve this issue? This is consistent irregardless of compiled FPGA VI.
