        @lin 你好,gc8034这个我们不清楚。 我们自己的相机模组有配置好的dts,你可以作为参考。

            @lin 一般来说,这东西取决于/boot/extlinux/extlinux.conf的配置。

              但是内核打印信息
              cf1c6546-4904-4a31-a6ee-3a8f1a01f415-image.png
              使用的设备树文件是roc-rk3588s-pc-mipi101-M101014-BE45-A1-v12.dtb,这是为什么?

                @lin 我感觉v12.dtb和没有这个后缀的dtb是一个。你可以看看。
                这东西是firefly在基于rk的系统上封装的,你也可以问问firefly的工程师。

                  相机的reset是低电平有效,为什么给的例子中设备树写的是高电平有效?

                    @veye_xumm
                    这个gpio_set_value_cansleep()函数将reset_gpio赋值为1,是让reset有效?pwdn_gpio该如何赋值呀?

                      @lin 实际上我们的mv系列相机只有一个ENABLE引脚,高电平使能相机,低电平相机将断电。

                      firefly的软件有两个引脚,实际我们的转接板也只用了一个。
