TDA2EXEVM: UTILS: MBX: Utils_mbxSendCmd(): Msg Alloc Failed (0)!!!

Hi sir,

I ran tidlOD use case with a 1280x720 resolution model.

I modified resolution relating part in tidlOD.c (such as display, grpxSrc) to fit my model.

I also modify vpeLink_drvCommon.c according to this thread ().

The detected process will be hung after starting detection process for a few seconds.

1. Here is the error message when detected process stops,

[DSP1  ]     46.671628 s:  Assertion @ Line: 782 in tiop/tiopLink_algPlugin.c: freeId != -1 : failed !!!
[DSP1  ]    169.284572 s:  UTILS: MBX: Utils_mbxSendCmd(): Msg Alloc Failed (0)!!!

2. Here is the inBufStats status in AlgorithmLink_tiopProcess() before error,

[2020-03-12 17:29:38.765] [DSP1  ]     80.356981 s: inBufStats 0 1
[2020-03-12 17:29:38.796] [DSP1  ]     80.357042 s: inBufStats 1 1

[2020-03-12 17:29:38.796] [DSP1  ]     80.357073 s: inBufStats 4 0
[2020-03-12 17:29:38.796] [DSP1  ]     80.357073 s: inBufStats 5 0
[2020-03-12 17:29:38.796] [DSP1  ]     80.357103 s: inBufStats 6 0
[2020-03-12 17:29:38.859] [DSP1  ]     80.453760 s:  Assertion @ Line: 782 in tiop/tiopLink_algPlugin.c: freeId != -1 : failed !!!

If I'm not misunderstanding, the buffer 2-6 are still available, but the error (tiop/tiopLink_algPlugin.c: freeId != -1) shows there is no free buffer can be used.

3. All things will be fine if I run with 768x320 model.

Can you suggest me how to fix it?

Thank you,
Gary

Hi Gaviraju,

Here is the debug log 4645.logs.txt

I found that when the error happened, the tiop buffer couldn't be released properly.

And this was due to incorrect bufferID in tiopReleaseLockedBuffer() ( tmpId = -2010018329)

This error will usually happen when the capture sense changed.

Please suggest me what can I do next.

Thank you,
Gary

Hi,

Any suggestion?

In my further testing , the tmpID should be positive.

[2020-03-16 13:08:36.081] [DSP1  ]     33.191453 s: released tiopReleaseLockedBuffer in tmpID 2284948968
[2020-03-16 13:08:36.112] [DSP1  ]     33.191484 s: released tiopReleaseLockedBuffer out tmpID 2284948967

Thank you,
Gary

Hi,

You mentioned, "All things will be fine if I run with 768x320 model". So remove all your changes did for 1280x720 model then run the lowe resolution model( < 768x320) & let's see you will face the same issue or not.

Thanks

Hi,

No, it runs correctly when removing changes.

Can you advise the correct way to run tidlOD usecase with a 1280x720 model?

Where should I change?

Thank you,
Gary

Hi Gaviraju,

I temporary solved this issue by lower deploy.prototxt "keep_top_k" value from 20 to 10.

But 10 objects are not enough for my application.

So I still need your help to find the root cause.

How to deal with 20 or more objects at a time in my case?

Do you have any idea?

Thank you,
Gary
