1. 前言
这边使用Toshiba TC358748X 的DVP转MIPI的芯片，
通过排线连接到nvidia xavier平台，
通过移植官方通用驱动，调试过程需要一些问题
2. 硬件连接

5.分析track信息
kworker/0:3-1690 [000] …. 139.036764: rtcpu_nvcsi_intr: tstamp:4734276115 class:GLOBAL type:PHY_INTR0 phy:0 cil:0 st:0 vc:0 status:0x00000089
REG NVCSI_PHY_0_CILB_INTR_0_STATUS_CILA_0 of the TRM 从这里可以看出是lane control error
可能原因： 可能是CSI信号或时序不符合MIPI规范
6. 示波器查询CSI信号（1）Toshiba MIPI out , 不连接xavier主控接口
（2） Toshiba MIPI out， 连接xavier主控接口
看着CSI信号时序是正常的
7. 重新测试如下命令/yavta /dev/video0 -c1 -n1 -s1920x1080 -fUYVY -Fcam.raw
