Hello,

I was trying to run TIDL segmentation example provided in debian@beaglebone:/usr/share/ti/examples/tidl/segmentation using ./segmentation. but it is raising following error:

debian@beaglebone:/usr/share/ti/examples/tidl/segmentation$ ./segmentation

CMEM Error: init: major version mismatch between interface and driver.

CMEM Error: needs driver version 0x4150002, got 0x4160000

TIOCL FATAL: The cmemk kernel module is not installed. Consult the OpenCL UserGuide at http://software-dl.ti.com/mctools/esd/docs/opencl/index.html

My kernel version is:

4.19.94-ti-r36

I have updated kernel from 4.14. Is that causing problem?

How can I recompile the codes which use TIDL library?

If I try gcc main.cpp in same segmentation folder it raises

debian@beaglebone:/usr/share/ti/examples/tidl/segmentation$ gcc main.cpp

main.cpp:44:22: fatal error: executor.h: No such file or directory

#include "executor.h"

compilation terminated.

Also can we use TIDL in python?

Thanks.

Hi Prathamesh, I heard back that updating kernel without updating u-boot, fw among other things to the exact correct version is always a cause for issues. Could you update the whole PSDK to latest image and give a try?

thank you,

Paula

Hi Paula,

I think I already have latest version Debian 9.9 2019-08-03 4GB SD LXQT for BB-AI. http://beagleboard.org/latest-images . I heard that next image is supposed to be launched in April 20.

I tried reverting kernel back to 4.14 and that works. But compiling codes is still problem with that. Only pre-compiled files run.

Could you update the whole PSDK to latest image and give a try?

--> I followed steps given in https://beagleboard.org/upgrade for updating kernel. I am not sure how to do what you want me to do. Can you please help me out with steps to do that.

P.S : I am not trying to compile with cloud9. I want to do it for codes provided in /usr/share/ti/examples/tidl/.

Thanks,

Prathamesh.

Hi Prathamesh, as BB-AI uses Debian (and not TI's Linux PSDK) I would suggest to rely in Debian's community support. It seems to me as a kernel/driver mismatch, but not really sure how to guide you to fix it.

If you need to know how to get BB-AI community support, please let me know.

thank you,

Paula
