Hi,
I am trying to generate test pattern using DS90UB954.
I am getting a pink color pattern.

It should be generating pattern in 8 different colors.
How to solve it ?
Thank you in advance.

Sorry that we didn’t try this test pattern generator before. What is the expected result?

Any requirement for this generator? For example, specific format or color space.

Hi @WayneWWW ,
I am using the ov5693 camera driver to generate pattern from The Deserializer(DS90UB954). I used the Exact registers given by the vendor to generate csi mipi data at RAW10 1080p 60fps.
The pattern capture was success but the pattern is only in pink color, it is expected to show 8 different colors.
Like this…

Can you identify whether this issue happens on csi side or the HDMI output side?

Hi @WayneWWW ,
The issue is at the csi side.

What’s the result without DS90UB954?
Did you check the RAW image captured by v4l2-ctl?

Hi @ShaneCCC ,
The pattern itself is being Generated by DS90UB954, I don’t know how to check the result without it.

This is what I got for “v4l2-ctl --device /dev/video0 --all”

I mean bypass DS90UB954 and enable ov5693’s test pattern to clarify it.
Also check the RAW image captured by below command.

v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=BG10 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=1 --stream-to=test.raw
13

When I ran the v4l2-ctl command you gave I got the following output

test.raw (4.0 MB)

14

I check the raw image by 7yuv and get below result by RGB565 format.
Maybe DS90UB954 output pixel format didn’t correct.
