树莓派5 一个mipi接口连接相机无法识别问题

[sqf121]

你好，我在使用两个imx-642相机，
用 https://wiki.veye.cc/index.php/V4L2_mode_for_Raspberry_Pi 安装了驱动。
用树莓派5 CAM1可以打开并设置相机，但是CAM0口找不到相机。

尝试更换了相机，单独插在CAM0口上还是识别不了。

mipi接口是i2c-11和i2c-12吗？这两个接口好像是正常的。

这个情况是接口坏了还是漏了什么东西没有设置？

Hi, I had similar issue with another camera vendor and it was related to overlay file which was from RPi4.

And fixed by replacing :
cam0 = <&i2c_frag>, "target:0=",<&i2c_vc>
to
cam0 = <&i2c_frag>, "target:0=",<&i2c_csi_dsi0>

Did you install driver from "release" folder or built it manually from source code?
if manually you need use dts(dtbo) file from rpi-6.1.y-bookworm folder.

Correct camera location should be:
/axi/pcie@120000/rp1/i2c@88000/veyecam2m@3b
/axi/pcie@120000/rp1/i2c@80000/veyecam2m@3b

As I see your second camera on ic2@70000 similar as I had with wrong overlay file.

Thank you for your reply.

I used the script from the release folder to install the driver, and the operating system version is 6.6.20-1+rpt1.
So, while installing the driver, I think the DTS file used by the script is raspberrypi_v4l2/driver_source/dts/rpi-6.6.y/veyecam2m-overlay.dts, which already has cam0 = <&i2c_frag>, "target:0=",<&i2c_csi_dsi0>.

I compiled the source code, and now both cameras are recognized!
