[Camera] RPI-CAM-MIPI can't be loaded.

[dpcivl]

Hi, everyone.

I'm working on a project with the iMX93 EVK board and tried testing my RPI-CAM-MIPI camera. However, I encountered the following problem:

```sh
root@imx93-11x11-lpddr4x-evk:~# dmesg | grep -E 'ap1302|mx8-img-md'

```

Here are the details of my workspace:

- DISTRO: poky
- Bitbake image: core-image-base

I've followed the RPI-CAM-MIPI QSG document thoroughly and ensured I did everything as instructed.

Is there any problem with my DISTRO setting or image configuration? I would appreciate any advice or suggestions.

Thank you.

Hi,

Thank you for your interest in NXP Semiconductor products,

What revision is your board?

Does the issue repeat when using prebuilts from nxp.com?

NXP colleagues used the i.MX93-EVK prebuilt image downloaded from the NXP website, followed the release notes and downloaded the firmware using git clone.

This should be OK since they have successfully run this.

$ gst-launch-1.0 v4l2src device=/dev/video0 ! autovideosink

I'm trying to build my own BSP with Yocto Project. I know that you provide pre-built image and I could build it. For my learning, I just want to make layers for my project. Though I'm building 'imx-image-full' right now, I was curious about how I could use RPI-CAM-MIPI with poky distro in Yocto Project.

Probably it's due to the driver is not built with core image, let's see if this is reproducible on the full image.
