TDA4VM: Illegal instruction error while trying to run vision apps.

Hi Sundarraj,

Currently our engineer is out of office. He will be back tomorrow, so please expect a delay of 1~2 business days in response.

Hi,

Is the application being run on the PC emulation mode?

if yes, Do you have the j7_c_models downloaded?

This is happening in PC emulation mode. yes j7_c folder is available.

The program builds fine. But we keep getting this illegal instruction error in some Ubuntu PCs while others work just fine. We are not sure how to resolve this issue as it occurs selectively in only some PCs

Since, it is not seen in all the Ubuntu PC, the software is fine. 

I am not aware of stvRun.sh. Is this created by you?

For PC emulation, you would have to execute vx_app_stereo_depth from the vision_apps/out/J7/A72/LINUX/release/ folder

Are you doing the same? If yes, then you would have to check what is the difference between the working and non-working setups

We are using 18.04 version with ti-processor-sdk-rtos-j721e-evm-08_04_00_02

stvRun is a shell script created by us to run the vx_app_stereo_depth. We don't see such folder in our setup, vision_apps\out\PC\x86_64\LINUX\ where we get the binary.  "vision_apps/out/J7/A72/LINUX/release/" there is not j7 folder.

Sorry, yes, the above folder is correct.

In that case, I do not see an issue with the SW. Please check your Ubuntu PCs and see if there are any differences or try doing a fresh setup of the PC emulation mode on the non-working PCs.
