          @hxm 把硬盘去掉就可以了。
          你这个硬盘是个启动盘。烧写的时候你说如果用不到,就不需要接硬盘。现在系统是在tx2本身自带的EMMC中的。
          如果你开发程序需要硬盘做扩大存储,建议你把硬盘接到电脑上重新格式化一下。或者更改tx2的系统启动盘优先级,改为emmc有限。——跟电脑改启动盘的方法类似。

              @veye_xumm 然后输入:dmesg | grep mvcam 命令后,输出还是为空,麻烦您看看

                你这个启动日志还是不对啊。

                [    0.000000] Booting Linux on physical CPU 0x100

                刚才这个日志是断电,拔掉硬盘之后,重新上电输出的吗?
                有没有做过类似什么系统恢复的操作? 或者看没看到过系统recovery的提示?

                  @veye_xumm 您好 自从贵店烧录系统后,我回来除开加了个SSD后,没有经过其他任何操作。下面这个是reboot后的日志log.txt

                                            @hxm 这个相机本身并不具备内存和整帧缓存。因此相机本身是的延迟是微乎其微的。 你所说的延时应该是播放软件的帧缓存的整体延迟。你可以看看有没有配置降低缓存的buffer数量的地方。
                                            如果你自己写程序去处理数据,缓存完全就是你自己控制了。
