SK-TDA4VM: How to let 2x CSI RPI cameras preview + AI running demo on the SKEVM?

HI Champs:

I have modified the new yaml.

1 is only enabled the #2 CSI cam.

1 is enabled #1+#2 cam.

Both are running without error logs.

But, There is no display onto the kmss (HDMI LCD), please help.

Hi Rio,

A bit confused about the issue here now.

In the previous thread, you had mentioned that you The rpiV2_cam1_example.yaml test with /dev/video2 still runs correctly, and the ISP, AE etc seems to operate correctly. when running the rpiV2_cam2_example.yaml test with /dev/video18, the camera display looks very dark, as if the ISP is not operating, or the AE is not functional. Again here I am just trying to run CAM1 or CAM2 when both are connected to the TDA4VM SK

Is this issue not seen anymore? The current issue now seems to be as mentioned below

Could you tell me how was it being on display before?

Few queries on the yaml script shared:

1. In flow 1: [960,1000,640,360] : here Ypos + height : 1000 + 360 = 1360 > 1080 (if you are using a 1080p display)
    Could you test input 1 with [320,180,640,360] ?

2. I see that both input0 and input1 are having subdev 2. Could you please check what the subdev is for both the devices?

3. Could you please share the setup script logs where the cameras are detected?

Hi Rio,

Thank you for the update. Could you please let me know what the issue was? 
Was it because of subdev or the display parameters [960,1000,640,360]?
