OMAP4430 : Ducati exception with OV5640

Frédéric COIFFIER
Prodigy 50 points

On our custom OMAP4430 board (based on the PandaBoard), we're using an OV5640 sensor.

To support it, we're using the last Ubuntu 12.04 with the ti-ubuntu-3.4.0-1490.11 Linux kernel. We have build the last gstreamer0.10-openmax_0.10.0.4+ti1.6.7.3-1_armhf.deb from the Git repository.

And thanks to our NDA, we've got a copy of the Ducati firmware source code OPBU_Ducati_GLP1.6.7.zip.

Our purpose is just to take photos with the OV5640. So, we modified the Ducati firmware for the Panda platform to support the OV5640 (which is already supported by the Blaze platform).

Thanks to the following command, we succeed to take a photo :

gst-launch omx_camera mode=3 device=0 num-buffers=1 focus=2 focus-mode=1 focusweight=1 iso-speed=200 qfactor=90 name=cam cam.imgsrc ! queue ! "image/jpeg, width=2592, height=1944" ! filesink location=/tmp/test.jpg

Unfortunately, if we try to take several photos, the Linux kernel crashes :

This exception occurs in the auto_white_balance_delete_stereo() calling awb_alg_dcc_tuning_dcc_bin_free() calling TIMM_OSAL_Free() : in fact, the function tries to free an invalid pointer.

But this code can work during the first 12 taken photos and can crash at the 13th. So, this problem can be due to a memory corruption or an erroneous code in awb_alg_dcc_tuning_dcc_bin_free() which tries to free a not initialized pointer.

But the source code in auto_white_balance_delete_stereo() and awb_alg_dcc_tuning_dcc_bin_free() isn't provided with Ducati source code : only the subs.aem3 library.

So, we have several questions :

  • Is it a known problem for the Ducati development team ?
  • Can it be due to a bad initialization of the OV5640 (in fact, there is no DCC for AWB algorithm with this OV5640 sensor) ?
  • Is there a way to get an update Ducati source code or the source code of the subs.aem3 library ?

Regards,

Frédéric

    OV5640 is a SoC sensor which means that AWB runs on the sensor, not OMAP. Also, auto_white_balance_delete_stereo library does not get involved unless there is a stereo 3D usecase. As I understand your usecase is single camera. Please double-check if the crash is originating somewhere else.

    I double-check by putting a debug message before and after the call to pBalance->deallocate(pBalance->handle_stereo); in sys3aDestroyAlgorithms() (where pBalance->deallocate = auto_white_balance_delete_stereo). So it's really this function which generates the exception.

    Maybe the stereo algorithm is allocated even if it's not used with the current sensor.

    I've found how to change the default sensor in Ducati but is there something else to change to specify there is only 1 camera ? Do you think this Ducati release is safe for using it with our Linux version ?

    Mono camera and stereo camera is selected by the app on A9. I am not sure which test app you are using. In omapdrmtest, 0 = primary camera, 1=secondary camera and 2=stereo camera. Default is 2 which means that if you want to use just primary camera you need to pass the correct argument.

    Thank you for your answer.

    As mentionedin my first post, I'm using gstreamer with omx_camera :

    gst-launch omx_camera mode=3 device=0 num-buffers=1 focus=2 focus-mode=1 focusweight=1 iso-speed=200 qfactor=90 name=cam cam.imgsrc ! queue ! "image/jpeg, width=2592, height=1944" ! filesink location=/tmp/test.jpg

    I am not sure where gst plugin for OMX camera came from. In TI recent releases this was not supported. Only way to test camera is omapdrmtest application. This is most likely as gst plugin issue.

    You may be right : I've found a second issue with Gstreamer but at Linux kernel side. Each time, I take a photo, ~11MB of shared memory seems to leak.

    But regarding omapdrmtest, where I can find the corresponding Ubutun package to test it ?

    Do we have to build a git version like this one ?

    That's correct.. you will need to download and build it.

    Thanks Mayank for your answer and I'm sorry to disturb you again.

    I succeeded to build omapdrmtest and now, I have the corresponding omx_cam_test binary.

    As my initial purpose is just a take a JPEG photo, how can I use this omx_cam_test application to achieve it ? It seems to only be an unitary test application. Do I have to modify it ? If yes, do you think that we can obtain a result in a reasonable time ?

    Currently, omx_cam_test gives me the following output :

    Currently omapdrmtest is designed to support very basic preview functionality. You can add more features like JPEG capture by referring to CameraHAL implementation in android.

    I am using the same camera and facing similar problem but kernel stack trace is different (can see in thread http://e2e.ti.com/support/omap/f/849/p/288060/1004862.aspx).

    Is there any solution to this problem?
