How to run executable after bootup automatically in linux

chandraevolute — Wed, 10 Aug 2016 06:10:09 GMT

I am using poky build toolchain for imx6ulevk board. Using kernel version 3.14.38 and poky version 1.8. I am able to run the application manually after bootup with command ./Executable. But the application needs to be ran after bootup automatically. Is there any way to do it.

Hi chandra,

Sure! The simplest way to do that is to add this command in /etc/rc.local script, so that it will be executed automatically during startup.

For example, you can add:

cd /usr/bin (where you put your application file)

./your_application

If you want it running in background, you can use ./your_application &

You need to add the application into some startup script like /etc/rc.local.

However you need to make sure that all required services of the system are already running at the time the application starts.

Have a great day,

How can I put the application in /usr/bin as i develop application outside the build. I want it to be a part of my image build. So when I do bitbake core-image-base my application should compile generate executable and sit in /usr/bin and I will write the start up script as you suggested. Do i need to add a layer for that??

I need one more help also where to get the set_image_autologin() function??

Hi Chandra,

Sorry for the delay!

If you are just testing your application on the board, then actually there are a lot of methods to put your application to /usr/bin. For example, if you are using SD card as file system, then you can cp the application to /usr/bin. If you are using eMMC, then maybe you can try scp, or unpack rootfs.tar.gz, cp your application to /usr/bin, repack it to rootfs.tar.gz, and then use mfgtools to download it to eMMC.

But if you are providing your application to your customers, then the answer is yes. To create a new layer in Yocto, you can refer to Yocto Project Development Manual

For auto-login function, you can refer to Reg: Auto-Login and run a script Automatically

Best regards,

Danwei Luo
