Hello,

Would you tel me about a limitation of frame periodicity?

I have tried to use OOB demo but a program halt with below error massage when there are moving targets.

{module#9}: "../objdetrangehwa.c", line 644: error {id:0x10000, args:[0x1b44c, 0x1b44c]}
xdc.runtime.Error.raise: terminating execution
[C674X_0] xdc.runtime.Main: "../objectdetection.c", line 1988: assertion failure
xdc.runtime.Error.raise: terminating execution

I show configure file used for this Demo.

The program work well when I change frame periodicity 16.7ms into 33.3ms. 

I guess a program halt when processing time exceed frame periodicity.

Is my guess correct?

I show my environment.
