i have an embedded linux device and an application that has to start after boot.
linux : Linux 3.12.10-ti2013.12.01 armv7l

at the end of file "/etc/init.d/rc" , i added this line:

cd /home/root/ && /home/root/ApplicationName

it gives error: "Permission denied"
if i run the application manually one time, then it works fine at every start up.

i tried the line below but it gives error "command not found"

cd /home/root/ && chmod +x /home/root/ApplicationName && /home/root/ApplicationName

how should i start the application?
note: startup does not have a login.
