Hi teams

Recently,we are working on 960 deser chip.When I preview the picture,there is some problem.

I use the sensor of 953 ser  1920x1080

It use Internally generate frame sync.

The reg I set as below:

i2cset -f -y 8 0x3d 0x4c 0x01
i2cset -f -y 8 0x3d 0x58 0x5e
i2cset -f -y 8 0x3d 0x5c 0x30
i2cset -f -y 8 0x3d 0x5d 0xda
i2cset -f -y 8 0x3d 0x65 0xba
i2cset -f -y 8 0x3d 0xb0 0x1c
i2cset -f -y 8 0x3d 0x70 0x1e
i2cset -f -y 8 0x3d 0x72 0x00
i2cset -f -y 8 0x3d 0x6e 0xAA
i2cset -f -y 8 0x3d 0x6F 0xAA
i2cset -f -y 8 0x3d 0x1f 0x00
i2cset -f -y 8 0x3d 0x32 0x01
i2cset -f -y 8 0x3d 0x33 0x03
i2cset -f -y 8 0x3d 0x32 0x13
i2cset -f -y 8 0x3d 0x33 0x03
i2cset -f -y 8 0x3d 0x20 0xFC
i2cset -f -y 8 0x3d 0x20 0x0C
Is there any problem ?  Could you  give some advise about it ?
BRs
thanks

    Hello YingJin, 

    I do not think you need to write to register 0x70 since you are using CSI mode. 

    It look like you are also sending BC GPIO to 4 953's. Is this correct? 

    Section 7.4.24.2 goes over internal frame sync and the registers to set and section 7.4.24.2.1 includes example code for a 50 Mbps BC and 4 SER attached. You can likely use this as a starting point. Let me know if that works for you. 

    Thanks, 
    Sally

    Hi Sally

    thanks for your  reply.

    1)  I  had comment the 0x70 reg write  it same as before.

    2) Yes, I use 960 generate the internal framesync signal pass through it by BC GPIO to 953 input gpio,then the 953 send it to the imager  sensor.

    the details as below:

    TI_F_SYNC   recevied the signal and send to the  imager sensor.

    3) I change the code as Section 7.4.24.2,The final effect is as follows

    There is one channel did not output.the other three is abnormal as  upside  Previous photos  of I sent.

    the code as below:

    Hello Yingjin, 

    Please make sure you are also configuring the GPIO on the 953 to also receive BCGPIO0/1/2/3 from the 960. Can you then also probe the GPIO on the scope to make sure you see the frame sync signal on all the 953's? 

    Thanks, 
    Sally

    Hi  Sally 

    thanks for your reply.

    I have try it.

    It still occur The image flickers

    If use another type sensor of 953,it does not need the trigger signal from 960,it display normal.

    If I use the type sensor of 933,which also did not need trigger signal,it also  works.  ok.

    Our poc hardware design can be uesd for 933 and 953.Will this have an impact  ?

    This scene of The image flickers only happened on 953 which  need trigger signal type sensor.

    BRs

    thanks

    Hi  Sally 

    The works fine sensor as below:

    It also 953  ser  which did not need trigger signal

    There's no flicker when I shake the camera

    BRs

    thanks

    Hi Yingjin, 

    I'm glad that there is no more flicker. Did you decide to remove the frame sync completely ?

    Thanks, 
    Sally

    Hi  Sally

    Finally,we will use the type which use trigger signal one.

    For now,we can sure the poc hardware has some affect.

    But I did not know how to chang it.

    Could you give me some design photo about the 953 

    BRs

    thanks

    Hello, 

    Can you send me your POC circuitry? The image you attached earlier in the thread does not show me the POC circuitry, so I cannot advise you. 

    Thanks,
