MIPI interface with Raspberry Pi

Follow
Irsvk

According to the release notes form September 2023 (https://github.com/IntelRealSense/librealsense/wiki/Release-Notes#pre-release-2521) support for a MIPI devices is available.

In the datasheet (https://dev.intelrealsense.com/docs/intel-realsense-d400-series-product-family-datasheet page 128-129), MIPI is also mentioned and how the routing is and the signal interface.

I'm very interested in using the REALSENSE with a Raspberry Pi and MIPI interface, but I can not find any information on how to connect them (cable, connector, ..) or guidelines.

Is this information available?

For a other device (instead of Raspberry) I was also not able to find information on how to connect them.

    Hi Irsvk  The MIPI support in RealSense SDK 2.52.1 onwards relates only to the D457 model of RealSense camera and its use on a type of connection called GMSL / FAKRA instead of USB.

    When this camera is used in GMSL / FAKRA mode, it requires the use of a separate hardware board called a deserializer and the use of a special MIPI driver.  Furthermore, this driver is designed for use with Jetson Xavier AGX computing boards and needs to be converted (ported) by the RealSense user for use on other types of computing board.

    I have not yet seen a case in which a D457 has been used with a Raspberry Pi board.

    Hi MartyG,
    Thank you for the explanation, it is very useful.
    Is the expectation that it be could/should possible to use the D457 with a Raspberry Pi board, when MIPI is used?

    I am not aware of a reason why it should not work with a Raspberry Pi.  And the Pi has Arm chip architecture like the Jetson board range does.  Until somebody tries it though then there is no way to know how well it would work with a Pi.  I would therefore approach it cautiously, keeping in mind the possibility that another type of board might have to be used.

     

    The ideal would be to use a Jetson AGX Xavier, as the RealSense MIPI driver is already compatible with it without having to make changes to it.
