SOLVED 在Xavier-NX定制载板上使用sc132
-
您好，
我在NX的定制载板上使用sc132。之前已经在改载板上配置了RPI Camera V2 相机，可以正常使用。我根据sc132的配置信息，修改了dts文件，但是没有识别sc132相机。以下是log信息。帮我看看是哪里有问题。

还是i2c不通。
按照log，您修改的dts文件，应该是按照- i2c总线1和8访问摄像头，这个需要您确认跟硬件的设计一致。
- 摄像头的device address，您配置为0x10,这个跟我们模组不一致。我们模组的i2c地址是0x3b。

安装您说的，我修改成0x3b,现在正常了。用什么命令打开相机呢,是用nvgstcapture1.0打开相机吗？

可以先试试这个。其他的参考上面的这个链接。gst-launch-1.0 v4l2src ! "video/x-raw,format=(string)UYVY, width=(int)1280, height=(int)1080, framerate=(fraction)45/1" ! nvvidconv ! "video/x-raw(memory:NVMM),format=(string)I420" ! nvoverlaysink sync=false
