你好，请问一下，加载.ko文件失败，提示“Invalid module format”，串口打印提示“disagree about version of symbol module_layout”，查看开发板运行版本和.ko版本一致，是什么原因引起的？

This error message means that the kernel and modules were compiled separately and from sources or configurations that were not same

You might want to examine this thread concerning how to match a kernel configuration prior to compile. The short answer is that a module of an incompatible configuration is attempting to load:

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

  1. jetson NX搭建环境，是用Ubuntu18.0.4，还是用Ubuntu16.0.4，还是两者都可以？我用ubuntu18.0.4的时候，在里面安装source insight后，菜单是乱的，因为这个问题，我换成了Ubuntu16.0.4，但是用Ubunut16.0.4的时候，打不开SDK Manager软件。

Are you asking this issue for your jetson NX or for your x86 PC host?

我之前用SKD Manager软件直接拉取Jetson NX镜像到开发板，克隆的linux内核代码是R32.6.1版本的，这两个是配套的吗，我用linux内核编译的.ko文件，加载.ko文件时，我用uname -r命令查看了开发板的版本是4.9.253-tegra，用modinfo命令查看.ko的版本也是4.9.253-tegra，为什么用inmod命令加载.ko文件出现“无效的模块格式”，这是两者的版本是一样的，为什么还出现这种加载失败的现象？如果是代码内核版本和开发板上运行的内核版本不一致，如果我用R32.6.1版本的内核源代码，需要用哪个配套的镜像呢？

Back to the basic question. Where did your “.ko” build? and where is your kernel coming from? Built by you? or directly provided by sdkmanager?
