无法获取csi摄像头的图像

[tiancai1234]

我们使用ORIN NX 8G，jetson版本为35.3.1，MAX9286进行四路摄像头的调试，在A底板上可以出图，更换到B底板上后，进行了设备树的匹配，发现无法出图，日志如下，请问我们能从日志获取到什么信息么？

hello tiancai1234,

that kernel messages reported means it cannot fetch camera frames.
may I know the difference between these two boards.

电路原理都是一样的，只是PCB板层叠厚度有变化；摄像头的滤波方案没有变化，和摄像头厂商确认是符合要求的。[quote=“JerryChang, post:3, topic:267140, full:true”]

Hi, please check and compare your A/B designs to find out the root cause since it is caused by different board design.

您好，我们发现正常的A底板csi0 CLK是200M，但是到了B板子变成了100M，请问这一块可能是什么问题呢

No idea. It could be the layout quality issue that cause data rate reduced.
