DS90UB936-Q1: 0x7A, CSI_RX_STS[3:1] = '111'

Part Number: DS90UB936-Q1
Other Parts Discussed in Thread: ALP

Hi Team,

Our setup is 935+936

In 936, we find 0x7A[3:1] = 111. We understand there may be some errors on 935 input(CSI) side. But we are not sure the real root cause.

Can you help share your experience which reason may cause the issue? Thank you.


Regards,

Roy

    Hi Roy,

    The issue may be coming from the imager or PCB layout. Could you check the following registers on the UB935 device:

    If errors are detected at these registers, then there may be issues with the image sensors. Or there may be an issue with the PCB layout between the image sensor and UB935 device.

    Best,

    Hi Justin,

    In our cases, those UB935 registers mentioned above are all '0', we only see bits set at UB936 registers(e.g. CSI_RX_STS, CSI_ERR_COUNTER).

    We wonder how such situation could happen, is it possible that:

    1. After UB935 syncs errors/error-count to UB936(e.g. CSI_ERR_CNT -> CSI_ERR_COUNTER, CSI_ERR_STATUS -> CSI_RX_STS), those bits at UB935 registers will be automatically cleaned or
    2. The errors are actually occurring in the path of CSI packet processing/transmission procedure between UB935 to 936, instead of the path of image sensor to UB935?

    Regards,

    Roy

    Hi Roy,

    When reading the CSI-2 error registers on the UB935 device, could you try to read the register first, wait about 10 seconds, and then read them again? Since these registers are cleared on read, I want to make sure that no errors were accidentally cleared and that there are truly no issues with the CSI-2 data being sent from the imager to the serializer.

    If there are still no errors detected by the UB935 serializer, then I would suspect that errors are being introduced over the FPD-Link between the SER and DES. Could you read the following registers on the UB936 and provide the results?

    Best,

    Justin Phan

    Hu Justin,

    Thank you for your comments. My customer dumped all necessary registers of 935 and 936 every 300ms, please see the attached file for full logs. Can you help let me know your idea? Thank you.

    Hi, Justin,

         Thank you for your response.

         We have followed your comment to test and dump all necessary registers of 935 and 936 every 300ms.
    I capture some message in below.

    CSI packet errors happen at 1536ms:

    From above register dump, while CSI error packet happen but 935 related status register have no any error report.
    RX_PORT_STS2's line count change error would keep 600 msec from CSI_ERR_COUNT begin count.
    But there is no any lock change or other connection unstable message appear.

    Is it meaning this issue caused of SerDes deliver packet unstable?

    What's factor may cause it? Could you advice?

    Thank you.

    Hi Roy and Blake,

    It seems that the UB935 is not detecting any CSI-2 errors, even after repeating the register reads. But there are still CSI-2 errors being detected by the deserializer in registers 0x4D, 0x4E, 0x7A, and 0x7B. In that case, it is likely that an external influence is introducing errors to the CSI-2 video data when it's being transported from the SER to the DES.

    Possible causes are: 1) Poor quality Cable, 2) Poor PCB design, 3) Poor quality connector, 4) Poor PoC design 5) External Noise

    I also see that the UB936 detects that LOCK has been lost (reg 0x4D[0] = 0, means no LOCK at the RX Port). This is further evidence that the link between the SER and DES may not be optimal.

    Can you try to run the MAP tool in your UB935+UB936 setup and then post the results?

    Here is a guide on how to use the MAP tool in a tab in ALP: https://www.ti.com/lit/ug/snlu243/snlu243.pdf?ts=1647537660783&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FDS90UB936-Q1 

    Can you also try changing the cable between the SER and DES, to see if that improves the link quality?

    Best,

    Hi, Justin,

          Thank you for the sharing.

          Please ignore the unlock at 16873 in previous log message, that was caused of the image sensor of our device was removed by operator after duplicate CSI error packet issue at that time. From our real fail case, there is no unlock message then appearing CSI error packets.

           if don't consider unlock factor, do you think the possible root causes are still as the following?

    1) Poor quality Cable

    2) Poor PCB design

    3) Poor quality connector

    4) Poor PoC design

    5) External Noise

    We will run the MAP tool with various cables to see if it's cable quality issue

    Thank you,

    Best regards,

    --Blake

    Hi Blake,

    Even if you ignore the LOCK loss, I still suspect that there is a link issue between the SER and DES. I recommend running the MAP tool across various cables. The "easiest" solution is if the cable is bad, which is affecting the link quality.

    I also suggest using a shorter cable, to see if the errors stop appearing, and a longer cable, to see if more CSI-2 errors appear. This also indicates an issue with the link quality between the SER and DES.

    The S-parameters of the PCB traces can also be measured to see if they meet our channel specifications. The UB936 datasheet has the required S-parameters for Single-Ended PCB Traces.

    Some optimization is required, depending on where the issue lies.

    Best,
