DS90UB936-Q1: Support needed for issues with Configurations of Ti936 and Ti935

Part Number: DS90UB936-Q1

Hello ,

We  are noticing issues with video buffer getting repeated in Valeo ECU for the camera connected through link from Ti 936 and Ti935   with 2  embedded line enabled . The issues are not noticed when embedded line are not enabled in the Ti936 . But we will need to support the embedded lines , The register 0x4B  is set to 0x92  . I am attaching the register dump of Ti936 and Ti935 can you check what possibly could be wrong in the configurations of Deserializers and Serializers

  • Hi Anith,

    There's no CSI, parity, or CRC errors in the link, and there's valid CSI output from the 936 (indicated by register 0x35). The configuration looks correct to me. Could you check the SoC side to see if the embedded data is forwarded?
