TDA2EXEVM: TIOP Link error. Utils_mbxSendCmd(): Msg Alloc Failed (0)!!!

Hi,

Can I know the SDK version? & also share a complete logfile in the text file.

Please share your input files, we will debug & get back.

Thanks

Hi Gaviraju

I trained two TIDL model(ssdJacintoNetV2) with different training set. One of them was ok, while the other one got this error.

In the same way, I temporary solved this issue by lower deploy.prototxt  "keep_top_k" value from 20 to 10.

>>>>> SDK version: 0307

>>>>> logfile &  prototxt used for import model: logfile.zip

Hi Gaviraju

"keep_top_k = 10" can not satisfy our application.

So I still need your help.

Thank you

Hi Gaviraju

I think this error mainly due to TIOP Link recive too many bboxes (up to 20).

Any suggestion?

Any updates?

Hi,

Can you increase the threshold value & see the result

Thanks

Gaviraju

consistently 

Hi Gaviraju

I increased the threshold from 0.3 to 0.5 in model import ( threshold = 0.5, keep_top_k = 20), but the inFreeBufIDs[0] still got a negative value after a while.

However, i temporary solved this issue by add the below code snippet in file tiopLink_algPlugin.c:

if (outArgs.iVisionOutArgs.inFreeBufIDs[0] < 0)
{
   Vps_printf("outArgs.iVisionOutArgs.inFreeBufIDs: %d \t freeId: %d", outArgs.iVisionOutArgs.inFreeBufIDs[0], freeId);
   outArgs.iVisionOutArgs.inFreeBufIDs[0] = 2 - freeId;
}

Besides, i found that threshold = 0.5 will be much stable than threshold = 0.3. In other words, threshold = 0.5 will produce less negative value.

• threshold = 0.3 with  code snippet
• threshold = 0.5 with  code snippet

Can you offer an offical solutions for this issue?

Thanks

Hi,

Please do the below changes & see the result.

1) Set "threshold" = 1 & see the result.

2) file: vision_sdk/apps/src/rtos/alg_plugins/objectdetection/objectDrawLink_algPlugin.c

function: AlgorithmLink_objectDrawSetMetaDataBuf

for(bidx = 0; bidx < 20; bidx++)

file: vision_sdk/apps/src/rtos/alg_plugins/tiop/tiopLink_algPlugin.c

function: tiopCreateAlgInstance

pAlgCreateParams->numInDetections = 20;

In the above functions, the parameter is hardcoded to 20.

So can you play with the values 5, 10, 15, 25, 30 then see the observation

Thanks

Hi Gaviraju

I removed my code snippet in file tiopLink_algPlugin.c and ran my model with tidl_OD usecase.

Coressponding run time informations are shown in the table.

Thanks for your help.
