      1 VEYE-MIPI-IMX385在Raspberry Pi 4 Model B 4GB上的测试是OK的:

      1.1 软硬件环境:

      • 镜像版本:为了保留Raspicam apps,特意下载了最新的Buster版本:2021-12-02-raspios-buster-armhf,如下图所示:


      下载地址:https://downloads.raspberrypi.org/raspios_oldstable_armhf/images/raspios_oldstable_armhf-2021-12-02/2021-12-02-raspios-buster-armhf.zip

      • 应用软件版本:于2021年12月12日Clone到本地,属Github上的最新版本https://github.com/veyeimaging/raspberrypi

      • 硬件版本:Raspberry Pi 4 Model B 4GB

      1.2 硬件连接:

      1.3 软件测试过程截图:

      1.4 测试结果:

      可以看出,Raspberry Pi 4 Model B 4GB成功驱动了VEYE-MIPI-IMX385,并拍摄了一个12M大小的视频,该视频导出Windows后可以正常播放。

      说明VEYE-MIPI-IMX385本身是没问题的

      2 VEYE-MIPI-IMX385在Raspberry Pi Zero 2 W上测试是有问题的:

      2.1软硬件环境:

      • 镜像版本:为了保留Raspicam apps,特意下载了最新的Buster版本:2021-12-02-raspios-buster-armhf,如下图所示:


      下载地址:https://downloads.raspberrypi.org/raspios_oldstable_armhf/images/raspios_oldstable_armhf-2021-12-02/2021-12-02-raspios-buster-armhf.zip

      • 应用软件版本:于2021年12月12日Clone到本地,属Github上的最新版本https://github.com/veyeimaging/raspberrypi

      • 硬件版本:树莓派官方最新出的:Raspberry Pi Zero 2 W

      2.2硬件连接:

      2.3 软件测试过程截图:

      2.4 测试结果:

      在调试过程中:

      通过Raspberry Pi Zero 2 W的CSI接口已经成功驱动了树莓派官方摄像头OV5647,可以排除是Raspberry Pi Zero 2 W硬件的问题;也通过前面1.4章节排除了是VEYE-MIPI-IMX385硬件本身的问题;也更换过其它软排线,排除了软排线的问题;总而言之,已经排除了是硬件问题。

      软件测试过程也反复执行了多次,安装的还是Buster版本的镜像,带Raspicam apps的,但还是在Raspberry Pi Zero 2 W上得不到VEYE-MIPI-IMX385的图像。

      可以看出,VEYE-MIPI-IMX385目前在Github上提供的程序暂不支持Raspberry Pi Zero 2 W,希望可以早日支持。

      2.5 怀疑出问题的地方:

      新出的Raspberry Pi Zero 2 W在CSI摄像头接口那个地方的I2C引脚与老版本的不一样,而VEYE-MIPI-IMX385的驱动程序依然使用老版本的I2C引脚。

      当然上面仅仅是一种猜想,我们更相信官方的研发实力以及技术支持,期望VEYE-MIPI-IMX385早日支持Raspberry Pi Zero 2 W

        你好,在树莓派zero 2w上,camera的power on 使能引脚,需要单独执行:

        raspi-gpio set 40 dh
        

        完成之后,就可以在i2c-10总线上检测到摄像头了。

        i2cdetect -y 10
        

        能发现0x3b设备,并且脚本可以读写摄像头参数了。

        完成以上步骤,就可以正常使用veye_raspicam系列软件。
