| Ticket Name: RTOS/TDA2: No result for new use case | |
| Query Text: | |
| Part Number: TDA2 Tool/software: TI-RTOS Hi, we reference "vip_single_cam_lane_detection" and "null_src_dec_display" two use case and create a use case we call "null_src_lane_detection" Now, we reference "null_src_lane_detection" and "tidl_OD" two use case for our new use case I got the output below,but It looks have no result Can you tell us where is wrong? BR Allen | |
| Responses: | |
| Hi Allen, Please verify if all the usecase and algo parameters are set . As the default usecase works there will be no issue in algo or framework, Please re verify the usecase Regards Chetan.M | |
| Hi, I think I set all parameters I can run these two use cases separately but when I integrate these two use cases It have no result Is there anything I didn't notice? BR Allen | |
| Can you please send the usecase flow what is all connected in the chain | |
| Hi The below document is the use case I create chains_tidlODPrimax.txt UseCase: chains_tidlODPrimax | |
| NullSource -> Decode -> VPE -> Dup -> Merge_alg | |
| //TIDL_OD | |
| Dup -> Alg_tidlpreproc (A15) | |
| Alg_tidlpreproc (A15) -> Alg_tidl_Eve1 (EVE1) | |
| Alg_tidlpreproc (A15) -> Alg_tidl_Eve2 (EVE2) | |
| Alg_tidlpreproc (A15) -> Alg_tidl_Eve3 (EVE3) | |
| Alg_tidlpreproc (A15) -> Alg_tidl_Eve4 (EVE4) | |
| Alg_tidl_Eve1 (EVE1) -> Merge_OD (DSP1) | |
| Alg_tidl_Eve2 (EVE2) -> Merge_OD (DSP1) | |
| Alg_tidl_Eve3 (EVE3) -> Merge_OD (DSP1) | |
| Alg_tidl_Eve4 (EVE4) -> Merge_OD (DSP1) | |
| Merge_OD (DSP1) -> Alg_tidl_Dsp (DSP1) -> Merge_alg | |
| //LD | |
| Dup -> VPE_LD -> Alg_ImagePreProcess (EVE1) -> Alg_ImgPyramid -> Alg_LaneDetect (DSP1) -> Merge_alg | |
| //Display | |
| Merge_alg -> Sync_alg (DSP1) -> Alg_ObjectDraw (DSP1) -> Display_alg | |
| //GrpxSrc -> Display_Grpx | |
| Can you verify the output of each algorithm , And also the alg_draw parameters Regards Chetan.M | |
| Hi, Can you explain it in more detail? So, Is the problem occurred in the flow below? the pic below is the linking flow Is it has any problem? | |
| Hi, Have any update? BR Allen | |
| Allen , can you print the usecase stats 'p' and share it , Not able to suspect on the issue with the available inputs. Regards Chetan.M | |
| Hi, It is the use case stats below 2438.session.log BR Allen | |
| I see many times there are complete frame drops , Some times there is output but not consistent can you share the img file of the usecase . ? Regards chetan.M | |
| Hi, It is the img file of our use case below BR Allen | |
| Hi, Have any update? Is our flow wrong? BR Allen | |
| Hi Allen , What is the load of each core , Is the system overloaded and dropping the frames . Do you have a local TI FAE .? So that we can arrange for a call and see how we can debug further .? Regards Chetan.M | |
| Hi,Chetan Our FAE told to us we can't use the flow below is it really? he told us to another flow but I got errors after we try We'll post a new question for the error but, we want to know the answer about this. Is really true we can't use this flow for our customized use case? | |
| Hi, Have any update? Is really true we can't use this flow for our customized use case? BR Allen | |
| Allen , We will need to debug and find why the usecase is not up , There can be timing issue which is causing algo not to update . Can you try reducing the fps of read to 5 and try . Regards Chetan.M | |
| Hi, Chetan I am not getting your answer. Can you please elaborate? BR Allen | |
| Allen, In the usecase there are multiple paths from source (file read) to display, One of the path operates at lower fps then the frames are dropped , If you change the sync threshold to a high value then sync link will not synchronize the frames and hence it might be dropping many frames. We can debug this issue with a lower pfs , Reduce the read FPS to 5 and try running the usecase . Regards Chetan.M | |
| Hi, Chetan We try to reduce the read FPS to 5 but we got the same result Is right what I did? It is the use case stats below 5008.session.log BR Allen | |
| Hi, Chetan Have any update? If we change something setting wrong, please tell us BR Allen | |
| No the settings look correct, In this usecase many links are utilized and there might be delay in some links which is causing the usecase to fail , You will have to debug this and route cause the slower link Regards Chetan.M | |
| Hi, Chetan I am not getting your answer. Can you please elaborate? BR Allen | |
| Hi Allen, You will have to debug each path of the usecase by adding a null terminator in each path and check the output. Then keep the entire usecase running bypassing the algo and ensure chain is up Regards Chetan.M | |
| Hi, Did you able to resolve your issue. can you close this thread if resolved. Regards, Anuj | |
