[imx-tests] Compile mxc_vpu_test

a_alquézar · ‎08-05-2015

Hi everybody,

I downloaded the imx-test-3.10.17-1.0.0 and I would like to compile the mxc_vpu_test, but I can't.

output:

cc -Wall -O2 -c main.c -o main.o

In file included from vpu_test.h:24:0,

from main.c:26:

mxc_ipu_hl_lib.h:96:23: fatal error: linux/ipu.h: No such file or directory

compilation terminated.

make: *** [main.o] Error 1

And If I try to tell the compiler -I<path-of-kernel-source-with-drivers-installed>, always I have problems with a lot of libraries...

I wouldn't use the ltib tool or similars... I only want compile mxc_vpu_test using its Makefile.

And I try to do the things of the readme.txt file... but nothing :smileysad:

readme.txt:

"

2. Build Steps

==============

To build all the tests and bootloaders, run make as shown:

make PLATFORM=MXC27530EVB LINUXPATH=/home/marsha/LINUX2.6/linux \

KBUILD_OUTPUT=/home/marsha/LINUX2.6/kbuild/mxc27530evb \

CROSS_COMPILE=/opt/montavista/mobilinux/devkit/arm/v6_vfp_le/bin/arm_v6_vfp_le-

Note that you have to specify 4 things: PLATFORM, LINUXPATH, KBUILD_OUTPUT, and CROSS_COMPILE.

The build results will end up in the platform directory.

To build a single test add the test dir name to the above like:

make PLATFORM=MXC27530EVB LINUXPATH=/home/marsha/LINUX2.6/linux \

KBUILD_OUTPUT=/home/marsha/LINUX2.6/kbuild/mxc27530evb \

CROSS_COMPILE=/opt/montavista/mobilinux/devkit/arm/v6_vfp_le/bin/arm_v6_vfp_le- \

mxc_mu_test

"

How can I install -lpu and -lvpu in my compiler poky 1.7.1, and all the necessary libraries? Any idea?

Thank you so much,

Best rgrds,

Boadrius

Hi everybody,

Thanks a lot for all the replies

Finally I used bitbake to compile the mxc_vpu_test and the compilation works successfully, although it takes some time

$ time bitbake -c compile -f imx-test

real 4m36.702s

user 1m45.368s

sys 2m31.600s

$ time bitbake imx-test

real 0m36.152s

user 0m8.360s

sys 0m19.020s

I edit the main file under the PATH:

'fsl-release-bsp/build/tmp/work/wandboard_solo-poky-linux-gnueabi/imx-test/1_3.14.28-1.0.0-r0/imx-test-3.14.28-1.0.0/test/mxc_vpu_test/'

And I found the bin 'mxc_vpu_test.out 'under the directory:

'fsl-release-bsp/build/tmp/work/wandboard_solo-poky-linux-gnueabi/imx-test/1_3.14.28-1.0.0-r0/image/unit_tests'

After this two commands, I used

$ bitbake core-image-base

to generate the image with the new binari for my wandboard-solo.

Before running 'bitbake core-image-base' I edited the file 'fsl-release-bsp/build/conf/local.conf' to add the following packages in the image:

CORE_IMAGE_EXTRA_INSTALL_append = " \

gstreamer \

gst-meta-video \

gst-plugins-good-udp \

gst-plugins-good-rtp \

gst-plugins-good-rtpmanager \

gst-plugins-good-video4linux2 \

gst-fsl-plugin \

glib-2.0 \

nano \

openssh \

ethtool \

libstdc++ \

imx-test \

imx-lib"

Well... up to this point seems all right... but I have one problem that I can't understand...

When I execute the test 'mxc_vpu_test.out' in my wandboard-solo I found this error in the output:

[INFO] VPU test program built on Aug 26 2015 08:46:56
[ERR] Error in opening firmware binary file
[ERR] Please put bin file to /lib/firmware/vpu folder or export VPU_FW_PATH env
[ERR] VPU Init Failure.

So I export the environment variable but doesn't work... and the folder /lib/firmware/vpu doesn't

exist... it seems like the imx-lib described in the local.conf not exists in the image (I think so, but I don't know...)

So I executed the command:

$ bitbake -s > PACKAGES-BITBAKE

to try to find if imx-test is installed in my image:

$ cat PACKAGES-BITBAKE

...

imx-lib 1:3.10.53-1.1.0-r0

imx-test 1:3.14.28-1.0.0-r0

imx-uuc :0.5-r0

imx-vpu 1:5.4.28-r0

...

and yes it's installed.

The source code where fails is in the main.c

err = vpu_Init(NULL);
if (err) {
     err_msg("VPU Init Failure.\n");
     return -1;
}

And I don't find the source code of the function vpu_Init. I guess this function is included in some compiled library.

Anybody knows what is happening? What's the matter?

Why does it appear this error message?

[INFO] VPU test program built on Aug 26 2015 08:46:56
[ERR] Error in opening firmware binary file
[ERR] Please put bin file to /lib/firmware/vpu folder or export VPU_FW_PATH env
[ERR] VPU Init Failure.

I'm going crazy trying to solve this problem... Any idea?

Thank you so much!

Best rgrds,

Hi everybody,

Thank you very much for all the answers but this isn't what I'm looking for.

All that I want is edit the source of this test, mxc_vpu_test, and compile it using the Makefile, without use Bitbake... only using my arm compiler (poky 1.7.1).

Any idea?

dhavalvadhar · ‎08-19-2015

Hi Boadrius,

Are you able to build mxc_vpu_test without using bitbake i.e. using Makefile?

I want to build mxc_v4l2_test sameway. Can you please help me ?

@Biyong,

I have tried to follow the steps you have mentioned to build. But getting errors.

Appreciate your quick reply.

Thanks,

Dhaval

BiyongSUN · ‎08-19-2015

The compile error issue is a case by case issue to resolve.

If you don't have cross compile skill, please use the cross compile system yocto.

Yuri · ‎08-06-2015

Your idea to "edit the source of this test, mxc_vpu_test, and compile it using the Makefile,
without use Bitbake" is clear, but it is not so easy because of dependensies.

Regards,

Yuri.

I use the sdk, which has no imx_lib for vpu in the SDK. can not prove to you the build of mxc_vpu_test.

please make sure. you have create a correct SDK, which contains the imx_lib.

This is a basic concept of yocto development with SDK. you can refer to yocto document and submit you question to yocto, too.

Yuri · ‎08-05-2015

Boadrius, hello !

Under Yocto there is imx-test recipe. Please use it to build the tests.

$ bitbake imx-test

Have a great day,
Yuri

Hi Yuri,

Where the compiled binaries will be available after running the 'bitbake imx-test' command?

Does it include directly to the rootfs?

Thanks,

Dhaval

Yuri · ‎08-12-2015

The build result files may be found in

<build_dir>/tmp/imx6qsabresd-poky-linux-gnueabi/imx-test/<release>/image/unit_tests

Regards,

Yuri.

Yuri · ‎08-06-2015

Dhaval,

yes, finally, the binaries are deployed to rootfs : /unit_tests

Also

source code for LTIB unit tests

Regards,

Yuri.

dhavalvadhar · ‎08-06-2015

Hi Yuri,

So do I need to run the command 'bitbake core-image-minimal' after running 'bitbake imx-test', to add these binaries in the rootfs? Because I checked after building the imx-test, the timestamp of rootfs wasn't changed. So those binaries weren't included into the rootfs.

I also ran 'bitbake -c deploy imx-test', but got following error:

*****************************************************************************************************

NOTE: Preparing runqueue

ERROR: Task do_deploy does not exist for target imx-test

Summary: There was 1 ERROR message shown, returning a non-zero exit code.

*****************************************************************************************************

Thanks,

Dhaval

BiyongSUN · ‎08-11-2015

"also ran 'bitbake -c deploy imx-test', but got following error:"

bitbake imx-test-c deploy

please read the yocto document carefully then launch the command.

dhavalvadhar · ‎08-11-2015

Hi Biyong,

Thanks for your quick reply!

I have tried 'bitbake imx-test -c deploy', but getting following error:

**************************************************************************************************************

NOTE: Preparing runqueue

ERROR: Task do_deploy does not exist for target imx-test

Summary: There was 1 ERROR message shown, returning a non-zero exit code.

Also, can you please let me know how to build imx-test without using 'bitbake' i.e. using toolchain?

Thanks,

Dhaval

imx-test has no deploy task.

Hi Biyong,

Thanks for your reply!

I tried with that command and it build the imx-test successfully. But the compiled binaries weren't added in the final image.

Also, it would be great if you can help me to build these test apps without using bitbake.

Thanks,

Dhaval

BiyongSUN · ‎08-17-2015

I have replied before. You can use this way to compile one by one. By you need to resolve the cross compile by yourself.

Hi,

Can someone please help me on this? How to deploy the binaries of imx-test onto final image?

Thanks,

Dhaval

Hi Boadius

You can build mxc_vpu_test using yocto "bitbake imx-test".

It will build your test successfully.
