    Have you tried running the script in standalone, instead from systemD, did it run ? Can you check and change the permission of the /home/Colors -platform as you did for the script. Also check & is being passed as an option and hence the executable fails

    Hi Dwarakesh, thanks for your great support.
    issue fixed with below script.

    vi /etc/init.d/1sysconsole_app.sh

    #!/bin/sh
    # Important System Environment Variables
    SCRIPTS=/etc/profile.d/*.sh
    for f in $SCRIPTS
    do
    source $f
    done

    echo "********************Hello World!"
    /home/root/Colors -platform linuxfb:/dev/fb0 http://localhost:80


    thank you.
