DS90UB960-Q1: How to setting the DS90UB960 with Ser 913A

DS90UB960-Q1: How to use another port of DS90UB960

Part Number: DS90UB960-Q1

Hi teams

Recently, we are working on the DS90UB960,

We connect 4 camera sensor with DS90ub953 to DS90UB960.

The four cameras works ok.The data all output from port0 of DS90UB960.

They are video0-3,960 chip can mirror output data, we want to get the same data from another port, how should we use it?

Did I need to re register the new video node ?(Like video4-7)

BRs

thanks

    Hi Yingjin,

    Let me clarify, you have CSI port 0 outputting the 4 camera streams, and you'd like the same copy of data on CSI port 1 as well? If so, you can set reg 0x21[7] = b'1.

    Best,

    Hi Jiashow

    Yes,I had already config the reg 0x21 of DS90UB960 , The same camera data stream can be seen from the oscilloscope on port 1.

    What I want is On port 1, the data stream of single camera sensor can also be obtained.

    It like the port 0, data  stream as video0--snesorA  video1---sensorB video2---sensorC, video3---sensorD.

    1)   On port 1, Did I need to get a separate data stream from the driver.  ?

    2)  Just like register video4---snesorA  video5---sensorB video6---sensorC, video7---sensorD.Do I need to register a new driver node  ?

    Could I use like Q2  ?

    thanks

    Hi Yingjin,

    Do you mean:

    CSI Port 0: input stream from all four cameras

    CSI Port 1: input stream from just one of the four cameras

    If so, this is not possible. Each RX port can only be mapped to a CSI port (unless you do replication of CSI0 onto CSI1).

    Hi Jiashow

    What I mean is below:

    1 )  We only connect 4 sensors to 960 chip

    2)  We have set  960 reg 0x21[7] = b'1.

    3) Port1 can measure the mipi signal with an oscilloscope

    Q1 :  What I want to ask is that From cpu side,Can I also get data from four cameras separately in CSI B ?

             We have two applications that use data from four camera sensors at the same time.

    Q2:  Now,If the camera data obtained from this side of CSI B is also separate,in the driver should I register the video4-7 to get the same data  ?

    thanks

    Hello,

    CSI Port 0 and Port 1 are duplicates of each other in this case. You should be able to route CSI port 1 data to "CSI B". The data will be the same so it will be video0 - video3. 

    Best,
