因为NX MIPI接口与相机线序不同（刚好相反），使用转接板进行线序转接。</p>
<p dir="auto">（2）软件环境<br />
NX系统：ubuntu 20.04<br />
NX使用系统内核版本：# R35 (release), REVISION: 4.1, GCID: 33958178, BOARD: t186ref, EABI: aarch64, DATE: Tue Aug  1 19:57:35 UTC 2023<br />

RAW-MIPI-AR0234M驱动版本：nvidia_jetson_veye_bsp v1.29</p>
<p dir="auto">(3)问题描述<br />
① 使用“nvidia_jetson_veye_bsp v1.29”源码编译支持4 lanes的“dbt”文件，编译生成了“egra194-p3668-all-p3509-0000.dtb”文件，将“egra194-p3668-all-p3509-0000.dtb”文件更新到NX板子上，相机无法采图，使用“./mv_mipi_i2c.sh -r -f maxfps -b 9”命令输出最大帧率60fps,如图：<br />

是的，qv4l2拿到图像，进行转码，搬移，预览，做了很多工作。整个pipeline的冗长和软件效率的问题导致预览无法达到相机的输出能力。</p>

我们安装您的方法（修改“bus-width”为4；修改 “num_csi_lanes”为“8”），也将固件升级到1.09，<br />
但是4 lanes依然只能找到相机，而无法采集到图像<br />

这个文件，指的就是在dts dtb\RAW-MIPI-AR0234M目录下的对应文件。</h2>
<p dir="auto">我依然建议你先搞通2lane的。 如果你用你的底板搞不通，建议你用一下官方开发板的那个底板先。</p>

并将生成的“tegra194-p3668-all-p3509-0000-4lanes-v2.dtb”进行更新：<br />

2、使用“./mv_mipi_i2c.sh -r -f lanenum -b 9”确认输出为4 lanes，最大帧率120fps。<br />
<img src="/assets/uploads/files/1724295752731-5116f45e-200a-44fc-9afb-7a813233935a-image.png" alt="5116f45e-200a-44fc-9afb-7a813233935a-image.png" class=" img-fluid img-markdown" /></p>
<p dir="auto">3、问题依然</p>
<p dir="auto">4、“v4l2-ctl”和“vlc”都试过，无法采集图像；“sudo dmesg”没有报错。<br />

5、指的将“num_csi_lanes = ”改为“num_csi_lanes = &lt;8&gt;”？</p>
<p dir="auto">6、是使用的........\dts dtb\RAW-MIPI-AR0234M\路径下的dtsi，但是自己编译的dtsi，并没有“RAW-MIPI-AR0234M”路径，有个疑问是我们自己编译的“dts”文件怎么就能确定是与“RAW-MIPI-AR0234M”匹配？在编译过程中并没有发现与““RAW-MIPI-AR0234M””绑定的相关操作</p>

</ul>
<blockquote>
<p dir="auto">因为NX MIPI接口与相机线序不同（刚好相反），使用转接板进行线序转接。</p>
</blockquote>
<p dir="auto">看不清楚你接插件的具体样子。这种情况不需要做转接板。FFC线用同面线或者异面线就能实现完全的信号反序。 当然，你用转接板也是可以的。</p>

<p dir="auto">相机无法采图，使用“./mv_mipi_i2c.sh -r -f maxfps -b 9”命令输出最大帧率60fps,如图：</p>

<p dir="auto">写lanenum之后，读取出来确认一下。</p>

<p dir="auto">使用“vlc”采集图一直没有图像：</p>
</blockquote>
<p dir="auto">你现在这个阶段，建议先调通v4l2-ctl取图，然后再尝试vlc.</p>

</ul>
<blockquote>
<p dir="auto">疑问：在NX平台型下使用2 lane和4lane,都无法采集图，而使用i2c命令可以找到相机。</p>

<p dir="auto">无法采图时，可以另起一个命令行终端，用sudo dmesg命令，看看有没有什么报错。</p>

<blockquote>
<p dir="auto">具体编译过程见下图（修改所有的“bus-width”为4）：</p>
</blockquote>
<p dir="auto">改成4lane，tegra194-camera-rbpcv2-veye_mvcam.dtsi中，除了bus-width,还有一个地方需要改。<br />
<code>num_csi_lanes = &lt;8&gt;;</code></p>
<ul>
<li>6<br />
对于RAW-MIPI-AR0234M,需要使用下面这个路径下的dtsi来编译。<br />
........\dts dtb\RAW-MIPI-AR0234M\</li>
