Segmentation fault when training

[Wesley-Lin]

Hi Sir,
I think that my issue is related to platform, I mean ORK has some problem is ARM. Because the ORK can run on my x86 desktop properly, however, that happen in Tegra TK1 (ARM).
I post the gdb message.

gdb --args python ./training -c rospack find object_recognition_linemod/conf/training.ork --visualize

Hi,

Given the debug message, it seems that it relates to OpenCV. Did you try to
ask OpenCV forum about this?

Regards,
Ha Dang.

Hi @hris2003

I have not asked OpenCV forum yet, I will do it soon.
Would you mind tell me which OpenCV version is more suitable ? On my TK1, the OpenCV version is 2.4.11.
Thanks again for your reply, the issue bothered me for a few days.

[hris2003]

For what I know, ORK under indigo works best with OpenCV 2.4.11.

Backtrace stopped: previous frame identical to this frame (corrupt stack?)
(gdb)

Could you please give me some advise ?
Thank you

[hris2003]

Well, from the error message, it seems that linemod was trying to copy/get
the the image to build its modality layers. Maybe the image encoding on
ARM is different than on a traditional linux?

Do you think you can provide a rosbag of the training data on your ARM
processor? Or just make a rosbag on the ARM machine and run ORK with that
rosbag on a traditional linux?

Have you tried contacting OpenCV? Given that linemod is part of OpenCV,
they might have a better idea about the error.

Regards,
Ha Dang.

Could you please give me some advise ?

Can I ask another question ?
Is there no ones use ORK on ARM platform ? I think it is obvious issue, but I don't see such issue in issue list.
Thanks

Hi @hris2003

I had solved the issue, but I encountered another issue.
Now I can training at first, but it would stop during loading image, the error log is "NVMAP_IOC_FREE failed: Bad file descriptor".
Then I run program in gdb, there is no useful information. Please give me some suggestions.
