英伟达团队你们好！
我在xavierNX（32.4.3）上使用2x4 CSI-2，首次使用v4l2开启某路stream时，概率性会出现阻塞的情况，重启应用后恢复（只有第一次开启stream时概率性出现）。不具有个例性，每个摄像头基本是独立复现（比如只开启摄像头或同时开启多个，都有可能会出现）。

尝试了以下方式提高jetson端时钟频率但没用。

#!/bin/sh

提供问题触发时的dmesg和trace.log

请帮我分析下问题可能的原因，我现在对排查方向没有头绪。
如需要额外的信息或描述，可以随时提供。
感谢帮助！

Did you confirm the clocks set to max?
Looks like signal problem like the ecc error and paylod CRC error.

感谢回复！
我的时钟默认就是最大值，这点可以确认。即上电后/sys/kernel/debug/bpmp/debug/clk/vi/rate的值就是/sys/kernel/debug/bpmp/debug/clk/vi/max_rate，其余三个也是如此。而且我在开启摄像头之前，执行了最上面提高系统时钟的脚本。

有个关键点是：系统启动后，只有第一次开启通道会概率性出现这个问题，之后不管开关通道多少次都是正常的。从这个现象能不能说明是硬件稳定性的问题，或者是驱动bug？

Suppose it could be the sensor initialize timing problem.

您是指打开stream时的sensor初始化时序有问题，而不是加载驱动时的初始化，我理解的对吗？
因为我这个现象是概率性出现，拿示波器去抓十分麻烦。还是想得到更多的外围信息，尽可能缩小问题的范围。
有没有可能与pix_clk_hz 或者serdes_pix_clk_hz 相关？

  1. Yes.
  2. From the trace log looks like doesn’t matter with the *pix_clk_hz.
