DS90UB949A-Q1EVM: Will DS90UB949A-Q1EVM work TI 948

Hi Manoj,

Thank you for your question. it looks like you have lock between the SER-DES. For the 949A, could you please change the USB2ANY setup to UB949A instead of UB929. We need some more information about your setup:

- What modes are you using the SER-DES pair? These are covered in the "Device Functional Modes" of the datasheet.
- Could you use the display timings for the panel and use the pattern generator to get an output? You could try deserializer internal PatGen first. And then if that works, try the same pattern from the serializer side.

Let me know if this works or any observations.

Best regards,
Ikram

Hi Ikram,

I'm Madan, replying to behalf of Manoj.

We have change UB929 to 949, also trying the device in default mode. All default setting is done.

Prior to actual video source, testing the test pattern from serializer and deserializer side. Tested with the default pattern with color bar pattern and video control, using the internal timing control. Not seeing anything display on screen.

You can more details in attachment.

Also capture the register logs of serializer, deserializer.

Hi Madan,

Please use the Video Control section of the Pattern Generator tab on ALP to enter the display timings for the panel.  And also enable generator and color bars.



Best regards,
Ikram

Hi Ikram,

I have tried this setup but not seeing anything display over display.

Hi Madan, did you change the display parameters (Total Area, Active Area, Sync Width...) to match your specific panel? 

Hi Ikram ,

we continue the discussion in another thread.  Already another thread is going, so I'm closing this thread to avoid conflict.
