Start applications using WP7609

Hello guys! I build a new image for WP7609 board. I add some applications for this new image, like lighttpd and net-snmp. I would like to know how can I start this applications at boot? I tried add some scripts in /etc/init/d and /etc/rcS.d, and both paths I can’t initialized them.
I’m too tried create a simple script to start in boot using /etc/init.d/ but It can’t started. Now, my board not initialize. How can I recovery it?
Someone could help me about this?
