Luckfox Pico ProMax适配TC358743问题咨询
Posted: 2025-04-06 18:37
TC358743是一款HDMI-CSI的采集卡芯片，PiKVM里用的是Geekworm的C790
我想在Pico上适配这个采集卡，于是画了个转接板连接这两块板子，然后修改dtsi并在内核中开启TC358743选项
系统启动后，用media-ctl和v4l2-ctl对查看相关设备，显示如下的一些信息
想问下这样是可以还是不可以？还需要另外做什么驱动上的操作吗？我用v4l2-ctl -d /dev/video11 --set-fmt-video=width=800,height=600,pixelformat=NV12 --stream-mmap=3 --stream-skip=10 --stream-to=a.bin --stream-count=1 --stream-poll 等进行抓图显示VIDIOC_STREAMON returned -1 (Invalid argument)这样的错误
