CSI Camera pinout are **NOT** RPi 5 cable compatible

Hello,

I see the polarity is reversed for RPi5 22-pin connector on the board. The real RPi5 is

Whereas your datasheet mentions

Could you explain? My camera is detected with qcom-camss with upstream linux but refuses to stream.

HI

Our silkscreen marks define Pin 1 as 3.3V, which aligns physically with Pin 22 on the RPi5. Therefore, their actual pin definitions are identical. On Rubik Pi3, the marked Pin 1 also connects to Pin 22 (3.3V) of the module. We will revise the silkscreen mapping for Pin 1 in future revisions to avoid confusion.

How can you say pin definitions are identical when Pin 1 connects to Pin 22 (3.3V) ? Isn’t this inherently wrong?

How do you expect Sony IMX219 to work without pin remapping of the MIPI CSI2 connector with upstream linux? Does the qcom-ubuntu does it in firmware?

As shown in the figure, the corresponding physical location can be viewed in this way.
The NO. * marked on silk screen is just a mark, and the sorting of physical interfaces is the same.
