How to add a user-defined shell script ro run in DM8168 with DVRRDK 4.0?

Check the permissions of both files. You can rename S99reset.sh as S99zreset.sh (to execute late) or move S99zreset.sh itself to /etc/rc5.d. We have added S99synccmd script as part of dvr rdk packaging which gets executed.

I have checked the permission of both files.It is OK.

As the above photo,the S99reset have been put into /etc/rc5.d folder.

What is the procedure of adding S99synccmd as part of dvr rdk packaing which gets executed after power up?

Is there any difference with the operations we have?

Confirm your runlevel is 5 by typing runlevel in the target shell prompt. Try remanimg to S21reset .One of the earlier shell scripts could have caused error

I have typed runlevel,it appears:"N 5"

And I have relink reset.sh to S21reset.

and it's the same:reset.sh have not run.

No matter I link reset.sh to S99reset or S21reset.

I find that the reset.sh is executed after I type "reboot" in the shell.It seems that it is executed in a unexpected time.

Still puzzled.

It is because there is a K99reset in /etc/rc6.d

I can add a symlink in /etc/rc6.d to run when reboot.

But I can NOT add a symlink in /etc/rc5.d when power up.

Still puzzled.

It seems that I find the problem.

My reset.sh is 

echo "hello from dm8168"

but everytime boots up,there is no corresponding character printed from console.

So I add another command:

rm /testest

Then I reboot the board,I found that testtest in root path disappear.It is deleted by S99reset.

But the print will fail.Maybe it is because that I have modified the  issue.net and issue file in /etc folder,so every time it will print our company's logo:Maybe it is not a good modification.
