Part Number: PROCESSOR-SDK-DRA8X-TDA4X
Tool/software: TI C/C++ Compiler
I am working with PSDK_06_02_00_21 for TDA4x.
We have been provided with a custom patch over the PSDK_06_02_00_21 for a custom board.
We are working on an application which uses ISPless camera. Hence we have integrated VISS node in the application.
The application with only VISS node runs fine.
We then added AWB node for Auto White balance. When the application is now executed, it hangs.
We debugged further to understand the location of hang and found that it gets stuck in VISS node in the function tivxWaitEvent().
There are 2 parameters that are enabled for VISS node when AWB node is enabled which are :
1. a delay object of type tivx_ae_awb_params_t and
2. another object of type tivx_h3a_data_t
Enabling these objects used by AWB node is causing the VISS module to hang at fucntion tivxWaitEvent().
It seems that it is waiting for some event from the driver which is not getting generated.
Kindly provide more details on the events used by VISS module. Also how could we debug further.
Have you tried using vx_app_single_cam which comes packaged in the SDK?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Mayank Mangla:
I have referred vx_app_multicam application to develop the application.
In reply to Jyoti Patil2:
What is the resolution of the camera? Which DCC file are you using for your camera?
In reply to Brijesh Jadav:
Customer has configured a custom ISPless camera and its resolution is 1280*944.
We are the DCC files provided with the configured camera sensor.
The application runs with only VISS module integrated. Once we enable the AWB node, the VISS module hangs in tivxWaitEvent().
A couple of suggestions:
1. Please try single camera app
2. Do you have any of the supported sensors in the SDK (IMX390, AR0233, AR0820). If yes, please try AWB with that.
3. Do you have the XML source for the DCC files you are using? Please share with us if you can.
