Running Linux Application on startup for LS1021a-twr?

datho — Wed, 06 Jan 2016 19:49:32 GMT

I'm trying to get the board to automatically run the .elf file, that was generated from the CodeWarrior Linux Application project, as soon as the Linux OS is finished booting. What is the best way to program the elf file onto the board and have it run at startup? I'm currently trying to look into how to do this on Yocto but I'm not familiar with the process.

Hello Dat Ho,

Please refer to the following method which I have verified on my target board.

1. In SDK 1.9, in the path sources/meta-freescale/recipes-extended/merge-files/merge-files/merge, create folder "usr/sbin/", "etc/init.d" and "etc/rcS.d".

Put your application file test.elf in usr/sbin/.

In the folder etc/init.d create a script "test" to execute test.elf, and add execution permission "chmod a+x test".

$ cat etc/init.d/test

echo "starting test.elf"

chmod a+x /usr/sbin/test.elf

/usr/sbin/test

In the folder etc/rcS.d, create a symbolic link for etc/init.d/test

$ln -s ../init.d/test S100test

2. Add "merge-files" in "IMAGE_INSTALL_append" of meta-freescale/recipes-fsl/images/fsl-image-core.bb.

3. Add MERGED_DST = "/" in build_ls1021atwr/conf/local.conf, and build rootfs image "bitbake fsl-image-core".

If you use SDK 1.8, the recipe paths are a little different.

merge-files:meta-fsl-arm/recipes-extended/merge-files/merge-files/merge/

core image: meta-fsl-networking/images/fsl-image-core.bb

config file:build_ls1021atwr_release/conf/local.conf

Have a great day,
Yiping

Thank you for replying Yiping, I did everything that you said to, but I ran into an error with the bitbake fsl-image-core command. I am running QorIQ SDK v1.8 and merge-files_1.0.bb (under recipes-extended/mergefiles) was throwing exceptions after I created all the folders and ran bitbake. I changed the maxdepth and mindepth to 4 to remove the exception that was thrown (they were both previously 1). I got the .elf file from CodeWarrior v10.0.7 for ARM v7.

After I programmed the ramdisk image into the board through u-boot and tftp, the board didn't have the .elf file anywhere. Instead the board just booted up like it did before, without any of the files from the merge-files folder.

From the merge folder I added:

*usr/sbin: UDP.elf

*etc/init.d: UDP (this is the script and its contents are below)

echo "starting UDP.elf"

chmod a+x /usr/sbin/udp.elf

/usr/sbin/udp

*etc/rcS.d: S100UDP

*contents of local.conf:

MERGED_DST = "/"

*contents of fsl-image-core.bb:

Hello Dat Ho,

No need to modify merge-files recipe, this package is just for users to add their own files.

Please refer to my merge-files folder in meta-fsl-arm/recipes-extended/merge-files/, which I have verified in SDK 1.8 environment.

Have a great day,
Yiping

datho — Tue, 12 Jan 2016 16:30:08 GMT

Your merge-files folder did work when I ran bitbake. The error I ran into only occurs when I try to add my own UDP.elf file from codewarrior. I noticed that one of the major differences between my UDP.elf file and the one you provided was that Ubuntu recognized your UDP.elf as a text based file and my UDP.elf file as an executable file. Have you been able to successfully bitbake a .elf file with executable code from a Codewarrior 10.0.7 Arm v7 Linux Application project?

Hello Dat Ho,

Please use the attached recipe to replace meta-fsl-arm/recipes-extended/merge-files/merge-files_1.0.bb, run "bitbake merge-files -c cleansstate", then build your rootfs filesystem.

Have a great day,
Yiping

datho — Wed, 13 Jan 2016 17:23:56 GMT

Using this .bb file, I'm able to add my own .elf and .cfg files to the RAM of the board. Thank you very much for guiding me to this point.

Is there a way to get the script to run automatically at startup though? I still have to log in as root and call the script myself.

Re: Running Linux Application on startup for LS1021a-twr?

yipingwang — Thu, 14 Jan 2016 12:11:58 GMT

In your previous description, you didn't edit the script UDP correctly.

*etc/init.d: UDP (this is the script and its contents are below)

echo "starting UDP.elf"

chmod a+x /usr/sbin/udp.elf

/usr/sbin/udp

Moidfy it as the following:

*etc/init.d: UDP (this is the script and its contents are below)

echo "starting UDP.elf"

chmod a+x /usr/sbin/UDP.elf

/usr/sbin/UDP.elf

If your problem remains, please provide the Kernel boot up log.

Thanks,

Yiping

datho — Fri, 15 Jan 2016 16:32:37 GMT

I did edit the script to replace udp.elf with UDP.elf but the issue was that I was still having to call the script myself after logging in as root. The files from the merge-files folder were placed in the root directory but not in the system locations. Instead of the folders being placed in /etc/init.d or /usr/sbin, they get created as etc/init.d and usr/sbin. I did edit the local.conf with MERGED_DST = "/", and it was previously blank.

Re: Running Linux Application on startup for LS1021a-twr?

datho — Mon, 18 Jan 2016 18:10:29 GMT

After looking through the QorIQ folder, I found another local.conf file and tried adding MERGED_DST = "/" to that folder instead. After I did this, everything was moved to the correct folders and the script began running at startup.

For QorIQ v1.8, the actual local.conf that you want to edit is actually under poky/build_ls1021atwr_release/conf/local.conf. I was editing the build_ls1021atwr_release/conf/local.conf that wasn't under the poky folder.

Thanks again for all your help Yiping.
