      树莓派配置i2c引脚使用./camera_i2c_config命令给摄像头供电失败。 连接摄像头在树莓派设备列表找不到设备。

      使用(./rpi3-gpiovirtbuf s 133 1)能够给摄像头供电,但是树莓派每次重启都需要重新给摄像头供电,

      成功供电后,树莓派设备列表还是没有连接的摄像头设备,使用命令获取不到图像。

        是的。就是这样的。

        成功供电后,树莓派设备列表还是没有连接的摄像头设备。

        你这个是raw版本的imx462,支持legacy mode,就是不会有/dev/video0的。

        使用命令获取不到图像。

        看你的命令,没有看出错误。使用i2c-10是没错的,-c 1对应使用板子上的camera1。只是-t 1000只有1秒时间有点短。

        题外话:
        以上考虑都是基于官方CM4底板进行的。如果使用微雪的CM4-IO-BASE-B底板,我们帮你们公司搞过一次了。印象里微雪这个板子的i2c跟mipi接口的对应关系是反的。请问一下之前同事的经验。
        现在我们手上的样品上次被你们公司要求,全部买走了。所以我们无法复现验证。

              使用一些第三方库(如opencv)去调用摄像头时,无法调用成功

                @yhb 本来就没说支持。
                我们有带isp的版本。 VEYE-MIPI-IMX462是可以的。 你现在用的这个是raw的。
