DS90UB954-Q1EVM: Sensor embedded line is not passed correctly over ub954

Dmitry Kuzminov

Part Number: DS90UB954-Q1EVM

When I'm using ub953+ub954 I can work correctly with sensor, however, when I'm using "embedded line" frame is broken.
Resolution is : 1280x800 10 bit

On Analog pad I do see the difference, when I'm configuring sensor to embedded line, I see that number of lines jumps from 800 to 801, however looks like embedded line is broken, when transmitted from ub954 to Jetson.

I previously opened issue in general support (CS0435520), I added screenshots there.

Hello Dmitry,

have you configured reg 0x4B on the 953 correctly?

But to be honest, the recieved number of lines looks correct in the 954. So, I think you need to contact the SoC vendor and ask them why the SoC is not able to detect the embedded extra line!!

So, I did progress with investigation.

What I see right now in Jetson, is that after ub954 new line is added to frame.

The moment I added to read one more line to Jetson controller, now I can see the image and no error from controller.

When I'm connecting CMOS directly to Jetson without ub954, with same sensor config, Jetson controller separates correctly embedded line from image and writes it to separate buffer, to the one that I provided.

So it looks like embedded line in mixed with frame, I'm now looking to frame to see what happens with line, is added to the end or at first line...
