Hi, I'm using DS90UB853EVM，But I cannot find the ovt_1280_1080_30fps_REMOTE.py file. Any one can help me?

    Thank you Steven. I saw the 954_953_sensor_setup.txt file.  I initialized 953-954 and camera with this script(coax RX1).  The camera register is initialized successfully( can see the signal). But no signal is output from 954 mipi interface. What may be the possible reason?

    please check:
    1. reg. 0x73/74/75/76? are they correct to match the sensor video format setting (line number and line length)?
    if yes, forwarding 2., if NOT, please check UB953 and its sensor setting correct or not? and the link status such as Lock indication.
    2. check whether the CSI2 forwarding is correct or not?

    My camera sensor resolution is 1920*1080， I checked register 0x73/0x74，its value is 1080(dec) and 0x75/76 is 2880(dec). Line number is correct and line length is not correct. Sensor setting is correct( I use another tool tested it, the image and resolution can be displayed on PC). LOCK led is off. What is the CSI2 forwarding ?
    Additionly. I have an OVT10460 Camera module(bought with 953EVM), I want to try this first and figure out what registers should I set for 953 and 954. I find no detailed imformation about this sensor. Just like the link below:
    e2e.ti.com/.../673258

    Could you provide some scripts to get this working? Thank you very much?

    From the reg. 0x75/76, the setting of sensor video output format is 12bits? (2880/1920 x8 =12)
    please check your setting of sensor, is it correct?

    regards,

    Sorry to reply you too late. Yes, the setting of sensor video output format is 12bits. Any problem?

    What's the difference between CSI-2 mode and RAW mode?  My sensor data format is 12bit, should I choose RAW 12 mode? The defalult mode is CSI-2,when I try to change it to RAW 12 LF/HF mode. The link is broken. What should I do?

    TI__Mastermind 30515 points
    the raw mode is used when paired with UB933/913A.

    Thank you for your reply.  Two more questions.

    1. I use 953 to generate 1920*1080 30fps RGB888 pattern, the 954 shows line length is 5760(1920*3), It regards RGB888 as three pixel, not one pixel. Its this normal?

    2.When I use 953 to generate pattern, there is no mipi signal in CSI TX port. When I use 954 generate pattern, I can measure the mipi signal.  I2C signal between 953 and 954 is OK. It seems the video cannot transmit from 953 to 954. What should I check?

    Any help would be much appreciated !

    Bruce,
    1. yes, it record the Byte number.
    2. do you set the forwarding mode in the UB954? this must be set. if yes, please check reg. 0x73~0x76 of UB954?

    regards,
    Steven

    Yes, I already set the forwarding mode in the UB954. The reg. 0x73~0x76 of UB954 is correct. Now I can see the mipi signal in CSI TX port with oscilloscope(using color bar or camera sensor). But I found that the signal from camera sensor is different from UB954. Is this normal? Which tools can I use to see the color bar or camera image?

    data lane signal from sensor:

    the csi2 output is dependent on the video format, not relied on sensor or internal pattern gen. basically the output is correct. I don't see any issues here.

    OK，Thank you very much.
    Now I want to change Coax mode to STP mode. After changed the hardware to support STP, the LOCK and PASS led can light. But ALP software shows link speed is 20M(Coax is 100M). Is this normal?

    yes, you should configure the bc rate reg. (please check d/s) in your case if you want to get higher bc rate.

    I use a tool box attached to UB954 to see the color bar or camera image. It can't display. The manufactory technical support says the wave signal from 954 is not correct. I don't know what to do next. Could you please give me a correct script to get 953/954 working?

    I can't understand your issue. can you have one block diagram here? and what is the issue?
    in TI's ALP tool, we have some refer. script for diff. setting in the link of UB953 and UB954.

    1. it could test issue, please make sure that your scope is set correctly. it sounds the ch1 is set as AC coupling also bandwidth is not good enough. please refer to TI's test plot in d/s.
    2. please refer to UB954 d/s on the CSI2 forwarding, or you can refer to TI's pattern gen. script in the installed ALP file (last version).

    Yes, you are right. Now, the 953-954 and camera is working well(Coax with synchronous mode and STP with asynchronous mode). I can see the image from display. Thank you very much!

    One last question. STP with asynchronous mode can work well now. How can I use STP with synchronous mode?

  • 0 in reply to Bruce Li
    TI__Mastermind 30515 points

    well done.

    you can check reg. 0x58[2:0] to set the correct back channel data rate (change the default 'b100 in STP strap mode to 'b110). then UB953 is set as sync. mode as well (same as the default coax sync. mode).

    best regards,

    Steven
