Tool/software:
Hi experts,
We have previously successfully used one DPI to output a set of camera data.
Now we intend to use dual DPI to output two sets of camera data.
I enabled ENABLE_DSS_DUAL in the app_cfg_mcu2_0.h file.
However, from the comments in ENABLE_DSS_DUAL definition, it is known that HDMI and EDP are enabled by default.
I made the following modifications to adapt to the dual DPI.

However, when running the application, it was found that the vxVerifyGraph interface was stuck, and there are no error logs.
Before running the application, I first run "source ./vision_apps_init.sh", and there were the following errors.
Could you please help me check if there are any problems or omissions in my modifications?
Thank you!
