Linux/TDA2PXEVM: IPC error

Part Number: TDA2PXEVM

Tool/software: Linux

Hi, 

I run in HLOS and my usecase is below.

// Capture
IssCapture -> IssM2mIsp -> VPE -> Dup_algPd -> Merge_algPd

// Drawing and Display
Dup_algPd -> Alg_FeaturePlaneComputation (EVE1) -> Alg_ObjectDetection (DSP2) -> Merge_algPd -> Sync_algPd -> Alg_ObjectDraw-> Display_Video

But, when I run the application the error happens.

[HOST] [IPU2 ] 60.400567 s: SYSTEM: NOTIFY: Send Event to [IPU2][9] failed !!! (status = -14)
[HOST] [IPU2 ] 60.400658 s: Assertion @ Line: 233 in system_ipc_bios_ipc.c: (Bool)FALSE : failed !!!

The usecase is something wrong?

Regards,

Heechang
