DS90UB929-Q1EVM: DS90UB929-Q1EVM

Part Number: DS90UB929-Q1EVM
Other Parts Discussed in Thread: ALP

On connecting the DS90UB929-Q1EVM board via HDMI to the Notebook, Windows doesn't detect it as an additional display.

Analog LaunchPAD detects DS90UB929, but shows "Linked to Video Source : No", and HDMI Status --> HDMI HPD : False, Freq: Not stable.

As a result there is no video output from the DS90UB929 HDMI .

The behavior is the same on Windows 10 as well as Windows 11 Notebooks, also with only board connected via USB to the Notebook ( no other peripherals), as well as login with Admin account.

    Hey Manoj,

    Yes, in order to get an HDMI signal detection, you need to connect a Deserializer to the DS90UB929 EVM Serializer. Otherwise, without a Deserializer connection, you would need to set register 0x5C bit[6] high to force link detection without a Deserializer connection present. This is how the 929 HDMI state machine works.

    Fadi A.

    Hi Fadi,

    The results are same with Deserializer connected - No HDMI

    Hi Fadi, one more information.

    All 3 bad parts have the batch number #81054000xx, whereas the good part has #79921000xx

    Hi Manoj,

    On the "good" board, is it detecting HDMI now and showing on ALP? Are you following the same procedures for all of them?

    What else have you tried till now for testing? Did you try the pattern generator or end-to-end video with incoming HDMI on the serializer?

    Does a PDB reset or software reset on the DES (register 0x1[0]), or plugging and re-plugging ever get HDMI detection?

    Best regards,
    Ikram

    Hi Ikram,

    Q1. On the "good" board, is it detecting HDMI now and showing on ALP? Are you following the same procedures for all of them? A1. Yes exactly the same procedure is followed. see the status on good board.

    Q2. What else have you tried till now for testing? Did you try the pattern generator or end-to-end video with incoming HDMI on the serializer? A2. Pattern generation is working on all boards(good and bad)

    Q2. Does a PDB reset or software reset on the DES (register 0x1[0]), or plugging and re-plugging ever get HDMI detection? A3. No, plugging and re-replugging doesn't resolve the problem.

    Best regards,
    Manoj

    Hi Manoj,

    Could you please check the 0xC general status register? Or better, could you share a full register dump of working and not working boards.

    Are the mode selections for both cases the same?

    Could you also assert and deassert the HPD using ALP, and also set the HDMI Reset 0x1[4] bit.

    Best regards,
    Ikram

    Hi Ikram,

    Attached the register dump of working and not working boards.

    Can you please elaborate in detail , how to perform the other two steps ? 

    1. Are the mode selections for both cases the same?

    2. Could you also assert and deassert the HPD using ALP, and also set the HDMI Reset 0x1[4] bit.

    Regards

    Manoj

    Hi Manoj,

    It looks like in the not working case (register read), the BRIDGE_CTL register 0x4F[0] has EDID access disabled. Could you change this to 0. 

    Also, this is set by the mode selection straps, so could you check if the mode straps are the same for all these boards? Since this is tied to "EDID_SEL", check MODE_SEL0 DIP switch in particular.

    Best regards,
    Ikram

    Hi Ikram,

    After positioning the mode straps same as in the working boards, the boards are working.

    Thanks for the support !
