How to make my app automatically run on startup (Leopard Board Ti DM 368 )

Problem is regarding leopard board (tms320 dm368 processor).
(Please ignore if i sound weird at some places as i am a complete newbieee in Leopard Board/LINUX )

I have a leopard board (tms320 dm368 processor)and
i want to run an app, automatically after boot up instead of manually typing the command in terminal.
So, I created the script file (named vcc_app) as follows

#!bin/sh
echo "My app is here"
/helloworld # The application

1 .after creating the script file i copied it in init.d
2. I gave the command

chmod +x /etc/init.d/vcc_app

(vcc_app is the name of script which I have created)
3. Then I gave the command

ln -s /etc/init.d/vcc_app /etc/rc.d/vcc_app

(rc.d is the run level directory i guess...b/c there is no rc1.d or rc2.d etc...not even rc.local)

Now, when i reboot the board nothing happens (Some times it says vcc_app not found..). Is there anything wrong .
Please help me out !

Many Thanks !

Which distro is running on your leopardboard?

Does your program work correctly if started from the command line (/etc/init.d/vc_app)? Does it start the board?

In general, it is not recommended to put your own code in /etc/init.d. Rather, make a startup script into a standard executable directory (like /usr/local/bin or $HOME/bin) and add the corresponding line into /etc/rc.local (although it may depend on the distro).

If you want to start your program by the init system in the way you're planning you have to make sure:
- it can run from /bin/sh
- it does NOT require any lib or program not yet started (e.g. programs running on other runlevels)
- it refers to full paths (not relative)

Its not a distro, i just have a bootloader(uboot,kernel and rootfs.(i am successfully booting it from SD card)
Just for more info:
There are no runlevel dirs like rc1.d or rc2.d etc. rc.local is also not present.All i have is rc.d

Yeah thats correct, but my app just prints "hello world"
When em running it manually from terminal it works fine.

2. There are neither runlevel dirs like rc1.d, rc2.d etc nor rc.local. i only have rc.d

Not all the scripts in rc.d and init.d are started just because they have tha run flag set!
What's inside your /etc/rc.d and /etc/init.d folders?

Here is the details of my init.d and rc.d
init.d

In a nutshell, if you look at the rc.d directory the S means start. Processes are started in order i.e S00xxx - S99xxx. Creating the link /etc/rc.d/S99your_app should run your hello world program automatically.
