DS90UB960-Q1: use replicate mode after working

Hello Elec, 

Thank you for your question. I want to clarify if you are planning to CSI-2 forwarding enabled.  This means you will have CSI data coming out of the port 0.  Is my understanding correct?

Hi Glenn,

Let me clarify in detail. Initially, the four RX port are mapped to CSI port0 and TDA2 receives CSI signal well. At this time, replicate mode is not enabled and CSI port1 is enabled. Now they want to enable the replicate mode, by setting setting 0x21 bit7 as 1. This happens after initialization, which means the system works for a while. So they want to know if this action is possible. If yes, how long is the latency between setting 0x21 bit7 as1 to 960 CSI port1 output signal?

Elec,

Thank you for your clarification. I will look into this.

It’s best practice to follow the sequence of disabling/enabling forwarding then configure replicate.

May you explain more details? Currently they enable the forwarding, then after a while configurate replicate mode. The time interval might be long. Is that applicable? Thanks.

Elec,

Don't understand your question. For replicate mode must be set before enabling forwarding. If you enable replicate mode after forwarding errors can occur.

Hi Glenn,

Understood,. Do we have related description in d/s? Thanks.

May you specify what error may occur? Thans.

Hi Elec, 

We looked error counter; this just give us an overall look at the errors.
