NXP RPI-CAM mipi not recognized

OlivierG — Wed, 05 Feb 2025 09:37:06 GMT

I have a RPI-CAM mipi conected with a IMX93 evk card

https://docs.nxp.com/bundle/UM11933/page/topics/rpi-cam-mipi_overview.html

This camera is not recognized by yocto : /dev/video not mounted

Is there a LED on the RPI-CAM mipi board ?
Is there a jumper or a switch to set on the IMX93 evk card to power the RPI-CAM mipi ?
Is is a DTB prebuild file to configure the mipi_csi port

Greetings

Olivier

Hi @OlivierG!
Thank you for contacting NXP Support!

The default device tree should work to work with the RPI CAM.
The RPI cam has a led that indicates that is working (See the attached image).
Are you connecting correctly the RPI Cam?
I don´t have issues ussing the RPI CAM by my side

Best Regards!

In the imx93-11x11-evk.dts i have the following block

&mipi_csi {

status = "okay";

port {

mipi_csi_ep: endpoint {

remote-endpoint = <&ar1302_mipi_ep>;

data-lanes = <2>;

cfg-clk-range = <28>;

hs-clk-range = <0x2b>;

bus-type = <4>;

};

This block is not for RPI CAM MIPI "ar0144" camera but for ar1302

what are the dts parameters for "ar0144" camera ?

greetings

Hi @OlivierG!

The ar0144 is managed by ar1302 (see the attached image), and there is not necessary any extra configuration for ar0144, but you need to download the firmware as we mention in UM11933.

Best Regards!

it works I must precise that there is a led on the MIPI board It didn't turn on because the MIPI connector was not well plugged This connector is very ambiguous
