1. 前言

上一篇是完成了驱动移植；
这里主要是记录驱动调试过程

2. 调试如下

（1）dmesg

...
[    7.108554] ov5693 2-0036: probing v4l2 sensor no i2c.
[    7.109445] ov5693 2-0036: tegracam sensor driver:ov5693_v2.0.6
[    7.109486] tegra194-vi5 15c10000.vi: subdev ov5693 2-0036 bound

Xavier无法捕捉画面。
/dev/video0成功出现后，尝试了tegra194-camera-e3326-a00的各种编辑，但捕获结果都是相同的。

（2） v4l2-ctl --list-formats-ext

尝试捕获时的输出显示了以下“无回调”和“无应答”消息，以及[RCE]消息。只要捕获的v4l-ctl命令处于活动状态，“no reply”和[RCE]消息就会重复。

从上面的trace信息看 MIPI没有接收到图像信号；

需要检测发送端是否有正常发送图像数据

（7）修改CSI发送lane数

通过示波器检测FPGA发送端的CSI信号，是正常的，默认设置的是4lane；
这里尝试将发送端修改为单lane，发现图像可以正常采集

【这里需要修改FPGA的发送lane数配置，以及xavier接收端与lane相关的配置】

（8）修改发送lane为4lane

由于实际使用是4lane的CSI通道，这样传输的分辨率和帧率才可以达到使用需求；
所以这里继续调试4lane配置；

将lane相关的配置恢复成4lane，调试如下
