starting script during boot process of Am335x EVM

Nina Weber

Hello,

I have added a script program.sh containing "cd /home/root/app && ./program" to the /etc/init.d folder, put a symbolic link to this script in the /etc/init.d folder (ln -s ../init.d/program.sh S99Program)

When I run ./S99Program my program starts. But when I reboot my AM335x nothing happens. I set all the rights of program.sh and S99Program with chmod 777 so there should be no problem there.

Can someone please help me?

Hi,

I will ask the SW team to look at this.

Hi Nina,
Take a look at this article(www.tldp.org/.../boot.html), you have to do:
ln -s /etc/init.d/program.sh /etc/rc.d/
in order to work.
Regards,
Boyko

update-rc.d -v program.sh start 99 5 .  #is also a variant which does the same as above.

Thanks for all your replies, I found out what was my problem. The method described in my first post works in general, but some libraries I used in my program didn't load until after booting, so adding the exporting of the Library path to my script did the trick.
My script now looks like this, where my additional libraries are located in /opt/lib:

"export LD_LIBRARY_PATH=/opt/ethercat/lib:/opt/SIU/lib:/opt/lib:$LD_LIBRARY_PATH
cd /home/root/app && ./program"
