Hello,

Now I setup Multi camera driver on TDA4,and now Multi camera driver can be found by APP,but can not get frame.

How to debug the Multi camera case,when I add new Multi camera driver does the Multi APP need modify?

How does the Multi APP select CSI channel?I used the CSI1 channel deserialiser and connect two cameras.

Plz give guide

Hello xu ji,

multi-camera example assumes that when the number of camera is 4 or less, it uses CSIRX instance0 and for more than 4 number of input cameras, it uses both the CSIRX instances. You would need to slightly change this logic. You could change the capture instance to 1 in the configure_capture_params in the ti-processor-sdk-rtos-j721e-evm-08_00_00_12\vision_apps\modules\src\app_capture_module.c file, when number of cameras are less or equal to 4. In this file, You could also change the other capture parameters like number of lanes, lane ordering, lane speed etc..

Please change the configuration in this file, as we have brought up the camera on the other thread and then check multi-cam example. it should work fine.

Regards,
