Part Number: DS90UB940-Q1
Does the DS90UB940 send the MIPI short packets (e.g. frame start, frame end) on the same virtual channel as programmed in CSI_VC_ID, or are they fixed to MIPI virtual channel 0? I have a case where image capture only seems to receive the synchronization information when using virtual channel 0. Thank you.
We will check into this early next week and respond back to see if we see the same issue.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Casey McCrea:
Sorry for the delay - we are still looking into this issue and will work to get a response ASAP. Are you still seeing the same behavior?
This just hit my desk. I've looked into this with both the design and systems teams - this feature should be working. Please let me know the configuration of your set up so I can reproduce it in the lab.
In addition to your set up details, please let me know the following information:
- Which Ser/Des combination?
- How are you programming the 940? (via local i2c or BCC)
In reply to Bryan Kahler:
Haven't heard back from you in a few days - hopefully no news is good news and the issue is now resolved. If not, to help replicate the issue in the lab, please provide the following:
Which serializer do you have paired with the 940 in your test setup?
Thank you for the responses. We have since been able to determine that the MIPI short packets are indeed sent on the same virtual channel as programmed in CSI_VC_ID.
