i.MX25 unit tests

albert_arquer — Mon, 17 Oct 2011 11:25:02 GMT

Hi, this might be a bit of silly question but here it goes.

When i build the kernel using the Linux-Target-Image-Builder (ltib) for the i.MX25 PDK a directory called "unit_tests" is created on the root directory. I assume these are tests probided by freescale to test the i.MX25 peripherics and this kind of stuff.

The thing is that I am very intereted on the source code of these test files but I can't seem to find them anywhere in the file system nor in the /ltib/ directory.

Anyone can tell me where they are located???

Thanks a lot in advanced :)

You can unpack them using:

./ltib -p mxc-misc -m prep

The source code will be available at <ltib directory>/rpm/BUILD/misc/test

To build and install you can do:

./ltib -p mxc-misc -m scbuild

./ltib -p mxc-misc -m scdeploy

Hi, I hate to bother you again but this morning I tried what you said first thing and I got the following error. I looked at google but I guess it is too specific. Following I am pasting the last chunk of the output where I think the error seems to be.

Hi Albert,

As already said by Rogerio, Install the supported packages, in the sequence. that itself is a solution.

You might need to be a root, if you want to install the mxc-misc package.

Hi,

You need to add the kernel headers.

Call ./ltib -c and mark "Include Kernel Headers" option.

You can try to build the unit tests again.

Rgds,

Rogerio

Rogerio, I already had the option "Include Kernel Headers" active all along. It still gives me the same error.

However, I have find another package called imx-test which seems to include even more testing programs than mxc-imx. Do you happen to know the difference between them?

Also, I don't quiet get the ltib tool. For example if I type "./ltib -p imx-test -m clean" it says that "imx-test is not installes" even if I have just run "./ltib -p imx-test -m install" right before.

I also don't get the difference between the option "prep" and "install". I mean, either way the package is getting uncompressed in /rpm/BUILD/ right?

I hate to ask fot all this trivial things, I would really appreciate it if you could point me to a tutorial or document where I could learn these answers myself.

Thanks a lot once again.

Hi Albert,

Don't hesitate to ask. This is the right place for trivial or not trivial questions.

imx-test is the newer test package, so if your BSP already has the imx-test package, please use this one instead imx-misc.

The prep option only unpack the package at rpm/BUILD/<package folder>, so to install a specific package you have 2 options:

1 - use prep, scbuild and scdeploy as mentioned before

2 - use: ./ltib -p <pakage name> -f (it will prep, build and deploy in a single command)

If you want to clear, you can simply remove the folder rpm/BUILD/<package name> . It will not clear the content of your rootfs.

Rgds,

Rogerio
