Hi ,

I am working IMX6ULL EVK , I have develop my application,

how I can auto start my application at startup before login ?

I see forums that modify /etc/inittab file, but in my file system this file there isn't.

I compile my SD image with 'core-image-base' option.

Do I must append other modules ?

At the moment I put the start of my application inside /etc/profile, but at startup I must put login and than the application start.

Can someone help me ?

Sergio

Please try to add starting your application into /etc/rc.local file.

Alternativelly you can place your script into /etc/init.d

root@imx8qmmek:/etc/init.d# cat test.sh
#!/bin/sh
echo test > /file.txt
root@imx8qmmek:/etc/init.d# ls -l test.sh
-rwxr-xr-x 1 root root 22 May 25 18:50 test.sh
root@imx8qmmek:/etc/init.d#

and add it into exact runlevel:

root@imx8qmmek:/etc/init.d# runlevel
N 3
root@imx8qmmek:/etc/init.d# cd /etc/rc3.d/
root@imx8qmmek:/etc/rc3.d# ln -s ../init.d/test.sh S50test.sh
root@imx8qmmek:/etc/rc3.d#

Hi Victor,

your example work well, the file .txt is create at start up automatically.

But when I add or substitute with "echo ./test_software" the program not start. (if I lunch ./test_software after login the program start well).

Have you other suggestion ?

Sergio.

"echo ./test_software" seems to be wrong.
The command echo does not execute its parameter. It only prints it.
You need to use something like "/bin/bash ./test_software" or simply "./test_software".

Hello Victor,

I have done ./test_software but nothink happening..... 

Have you test this suggestion ?

What permission must have the test_software file ?

Have you tried running the program by typing its full path? For example instead of ./test_software, try /path/to/binary/test_software.
