1 概述

FPD-Link SerDes III是由TI提供的视频流同轴远程传输方案。我们设计了FPD-LINK3-TX和FPD-LINK3-2RX电路板，可以实现1或2路MIPI图像的同轴远程传输，传输距离可达10米。

在Jetson Nano和NX平台上，采用1组FPD-LINK3-TX和FPD-LINK3-2RX电路板，即可提供1路摄像头的远传，采用2组则可以提供2路摄像头的远传。FPD-LINK3-2RX上，fpdlink通道为port0(J3)到J9。

在Jetson TX2和Jetson AGX Xavier平台上，采用1组FPD-LINK3-TX和FPD-LINK3-2RX电路板，即可提供2路摄像头的远传。FPD-LINK3-2RX上，fpdlink通道为port0(J3)和port1(J4)到J7,J7为一个4lan的mipi接口，通过虚拟通道技术，支持两路独立的摄像头数据传输。

在Jetson TX2平台，采用3组FPD-LINK电路板，配合1个ADP-N2，即可提供6路视频的远传。在Jetson AGX Xavier平台，采用4组FPD-LINK电路板，配合一个ADP-N3，即可提供8路视频的远传。

在应用层看来，FPD-Link通道支持所有MIPI摄像头功能，包括图像、i2c通信、同步IO、触发IO。
在使用CS-FPD-CAM时，必须要参考如下文章：

2 硬件准备及安装

Jetson NX connect with CS-FPD-CAMs(the same with Jetson Nano)
AGX XAVIER connnect with CS-FPD-CAMs
TX2 connect with CS-FPD-CAMs


注：FPD-LINK3-2RX需要12V供电。

3 更新Jetson系统

与更新Jetson Nano, Jetson TX2，AGX Xavier和Xavier NX系统步骤基本一致，注意dts、dtb、均采用fpdlink后缀的版本即可。driver源代码和Image，兼容FPD-Link和MIPI接口摄像头。

3.1 Image和DTB更新成功了吗？

3.1.1 对于Image

ls /sys/bus/i2c/drivers/

应当有 veye327 csx307 cssc132 i2c-ds90ub954 目录的存在

3.1.1.1 对于DTB

DTB在不同的平台和不同的摄像头模组都会有所不同。

- Nano A02

ls /proc/device-tree/host1x/i2c@546c0000/

- Nano B01

ls /proc/device-tree/cam_i2cmux/i2c@*

- TX2 Devkit

ls /proc/device-tree/i2c@3180000/tca9548@70/i2c@*

- AGX Xavier

ls /proc/device-tree/i2c@3180000/tca9548@70/i2c@*

- Xavier NX

ls /proc/device-tree/cam_i2cmux/i2c@*

应当可以发现摄像头型号和ds90ub954。
