Linux/DS90UB964-Q1: DS90ub964 sync forward mode, how to continue to forwarding, when one camera disconnected?

Hi,
you can use two options:
1. when working in sync. mode, for any camera port is plugged out, you can set register 0x20 to disable the CSI2 forwarding, other 3camera ports can be mapped in the CSI2 port;
2. set UB964 at RR mode. disconnecting any camera port do NOT impact others.

best regards,
Steven

Hi Steven:

1. when I disable the channel of the disconnected camera 【cam2】, the buf 5120x720buf [ cam1,cam2,cam3,cam4] will change to [cam1,cam3,cam4,....]，this is not a good practice.

2. I used the glsdk 7 04 00 03, but the bsp can't make RR mode for 4 camera work well. 

thanks.

Can you processor support VC of CSI2? if yes, the sequence "cam1, cam3, cam4" still can work as your processor identity camera channel through VC.

when sync mode, cam1 cam2 cam3 cam4 will sync base by cam1.
processor dra725 is support VC for CSI2, but the driver is not ready for multiple VC ID independent in sync mode;

when sync mode, cam1 cam2 cam3 cam4 will sync base by cam1/2/3/4 as all cameras are in synchronization. UB964 also can support 3cameras inputs in sync mode, so when you un-plug any camera input, you can set UB964 work at 3camera inputs with sync. mode.

best regards,
Steven

yes, I can use the 3 camera inputs with sync mode.
Is there any other method make the buf mem 5120x720 like [cam1,cam2,black,cam4] when the cam3 is un-pluged?
