GMSL方案，还是记录一下吧，调试过程中随手记录
比较杂乱，没有整理，随便看看吧

本发明提供了一种基于PCIE和摄像头同轴传输技术的多摄像头同测装置，其包括依次连接的图像采集及PCIE发送模块、同轴远距离传输模块、数字电源模块，所述图像采集及PCIE发送模块包括互相连接的PCIE接口和FPGA，所述同轴远距离传输模块包括用同轴电缆互相连接的芯片max9295A和芯片max9296B，FPGA通过I2C总线连接芯片max9295A，芯片max9296B通过I2C总线连接数字电源模块，每路摄像头分别连接数字电源模块，并通过MIPI接口和I2C接口与芯片max9296B连接。本发明的优点是：一个测试电路能够完成几十个摄像头的同时检测，大幅提升测试效率；模组通过同轴电缆实现摄像头MIPI数据的远距离传输，有效解决了MIPI数据远距离传输的问题，通过由MIPI信号转换为同轴再转MIPI，保障了MIPI信号的完整性。
问一下 MAX9295 对端用什么片子解串比较好
客户做ADAS（高级辅助驾驶系统）
模组这边是 MAX9295出来的
我需要一个解串芯片？
开始测试 MAX96705+MAX9286 画质不能满足要求，
Maxim的吉比特(千兆)多媒体串行链路(GMSL)方案可以对数字视频和音频数据进行串行转换，然后通过一对双绞线串行传输。另外，集成双向控制通道可以使能单个微处理器©对串行器、解串器和所有连接外设编程。在典型应用中可以省去远端微处理器及相关器件，如：时钟源/晶体和低压电源。此方案不但简化了远端设计，而且降低了系统成本、尺寸和功耗。但是，有些情况下，考虑到GMSL之外的特殊需求，系统中仍然在链路的两端驻留了μC.这篇应用笔记描述了如何连接两个μC，控制GMSL.

//MAX9288
The audio channel supports L-PCM I 2 S stereo and up to
eight channels of L-PCM in TDM mode. Sample rates of
32kHz to 192kHz are supported with sample depth up to
32 bits.
The GMSL
supply is 3.0V to 3.6V, the MIPI CSI-2 supply is 1.7V to
1.9V, and the I/O supply is 1.7V to 3.6V.

Mid f SCL range:
(I2CMSTBT 101, I2CSLVSH = 01) > 100 400
High f SCL range:
(I2CMSTBT = 111, I2CSLVSH = 00) > 400 1000
I2CSEL I 2 C Select. Control channel interface protocol select input with internal pulldown to EP. Set I2CSEL =
high to select I 2 C interface. Set I2CSEL = low to select UART interface.
//寄存器 0x1C
Set the I2CMSTBT (register 0x1C) to set the remote I 2 C
bit rate. If using a bit rate different from 400kbps, local- and
remote-side I 2 C setup and hold times should be adjusted
by setting the I2CSLVSH register settings on both sides.

新板子adsp影响调试的话，可以先在kernel下drivers\soc\qcom\subsystem_restart.c文件中，在"subsys->desc->sysmon_pid = -1;“后面加上一句"subsys->restart_level = RESET_SUBSYS_COUPLED;”，忽略subsystem异常，以便看能否先调试其它功能。adsp的异常再进一步分析
