（急！！！）JETSON TX2 + CS_TX2_XAVIER_1CAM_IMAX327 怎么正常启动？

[hello]

@veye_xumm

4.1步骤/dev/videoX检查设备节点，显示没有文件或目录，这个是怎么回事呢？

进行4.2.1视频预览测试没有出现预览：

[hello]

根据文档4.2的说明，一个摄像头对应video0，继续/dev/video0检测，结果：Permission denied，这个是咋回事呢？

当然，这个是设备文件，不能直接执行。你可以稍微补习一点点linux基础知识。 学习一下ls的用法。
现在你的系统检测到了。

这个有一点奇怪。你可以执行完preview命令之后，dmesg看看系统报什么错误。
另外建议你使用我们新版本的驱动，veyecam2m。做法就是用VEYE-MIPI-CAM2M下面的dtb文件。

[hello]

@hello

“另外建议你使用我们新版本的驱动，veyecam2m。做法就是用VEYE-MIPI-CAM2M下面的dtb文件。”
关于这个提供下下载的链接吧？
目前使用的是根据文档3.3.4中说明的版本：tegra186-quill-p3310-1000-c03-00-base.dtb
下载来源如下：

这个不是最新的吗？

另外使用新的dtb做法是直接拷贝覆盖吧？可要烧写步骤呀？

[hello]

@hello
下载如下的dtb

开启recovery模式，在host pc上重新烧写更新dtb（参考文档3.6.3）

烧写更新完成后发现摄像头sensor都检测不到了？？？

[veye_xumm]

@hello

1. 你重新烧过的系统，好像不是L4T 32.5.1吧？所以为什么要用这个Jetpack4.5.1下面的呢？
2. 用veyecam2m,dmesg就不要grep veye327了啊。

dmesg | grep veye

3. 请检测一下你的排线有没有插歪了的情况？

[hello]

@veye_xumm

之前的系统是32.5.1的，上次新烧的版本号为R32(release) Revision:6.1

用Jetpack4.5.1下面的原因是根据摄像头型号327，根据code的版面支持说明用的这个版本

[veye_xumm]

@hello 请用正确的版本，也就是jetpack4.6的版本

[veye_xumm]

@hello 请问解决了吗？

@hello 请问解决了吗？

你好，非常感谢答疑与帮助，目前可以摄像头视频图像已经调试出来了，抱歉回复有点晚

新的问题是这个视频图像出来后，窗口就退不出来了，全屏是视频窗口（想退出或缩小化），退回到终端或桌面不知道怎么操作?

谢谢

你在终端杀掉gst-launch-1.0进程也是可以的

现在全屏都是预览的摄像头画面，退不出来，进不了终端

[veye_xumm]

@hello 这个是由nvoverlaysink 这个sink决定的，它是个默认全屏的。

1. 你可以查查nvoverlaysink 的属性，增加个显示范围之类的参数。
2. nvv4l2camerasrc可以加一个帧数的参数，这样会定时退出。比如nvv4l2camerasrc num-buffers=300
3. 你可以从pc上ssh到jetson上，启动预览，ctrl+c就退出了。
