RTOS/TDA3XEVM: One camera fail in SRV

kenshow

Part Number: TDA3XEVM

Tool/software: TI-RTOS

Hi,

In the SRV use case, if one of the four cameras can not be connected, SRV will start with all cameras unable to be displayed. I want to improve so that it works with three cameras. How can I improve that way?

I would like to change the program step by step, but please advise first which sources to look at.

I use PSDKV3.05 and usecase “3D SRV 4CH ISS capture + ISS ISP + DeWarp + Synthesis (DSP1) + Display” with TDA3x RVP board.

You can look at the usecases @

vision_sdk\apps\src\rtos\usecases

The use case you are referring to should be in the 'iss_mult_capture_isp_dewarp_3dsv_tda3xx' and the primary file is chains_issMultCaptIspDeWarp3dSv_Display.c

Hi Shashank,

Yes. However, It seems that this code is not the cause of not being able to display all the cameras.

Which code is actually a bottleneck? Is it related to ISS setting or process?

Hi Kenshow-san,

I understand the issue that you facing, the issue is due to Sync link and down stream modules, as it expects 1 frame from each camera. Since one of camera failed, the Sync link will not forward composite frame.

This can be resolved with select link & merge links.
