Part Number:TDA4VM
Our camera stream is OVX3C—>Gw5200(ISP)—->UB935(SER)——>UB960—–>TDA4 CSI
During Debuging ,I have some problems :
1. When I set one camera work , the camera is working successful,and the dispaly has image.But I try two cameras with UB960 , the dispaly is nothing,and the vx_app_multi_cam is hanged .
=========================
Demo : Camera Demo
=========================
s: Save CSIx, VISS and LDC outputs
p: Print performance statistics
x: Exit
Enter Choice: x
2. In the camera config with one ,I set the Ub960 CSI speed 1600 {0x1F,0x00,}
and the TDA4VM CSI 1600{captureObj->params.instCfg[id].laneBandSpeed = TIVX_CAPTURE_LANE_BAND_SPEED_1500_TO_1750_MBPS; },
they will be not working ，and the vx_app_multi_cam is also hanged .
Here is my config for ub960：
One camera config：
