        这个是Image不正确的缘故。你可以检查一下是否替换了正确版本的Image和Image.sig到/boot下面

          @veye_xumm 是的,我用的这个8946f332-2987-46af-844d-dfcbb4de2e88-image.png
          已经把Image和Image.sig 放到了/boot

            感觉比较奇怪,像是Image没有生效。
            你可以试试

            dmesg | grep xumm
            

            如果是我们编译过去的kernel,应该会有信息。

                说明我们的kernel并没有生效。
                nx上最近有两个客户也反馈类似的问题。我们这边没有复现出来。客户那边后来通过重新烧写标准镜像再替换Image的方法就可以了。
                正常我们编译过的Image生效的话,dmesg是可以看到版本号的。
                Linux version 4.9.201-tegra (xumm@ubuntu) (gcc version 7.5.0 (Ubuntu/Linaro 7.5.0-3ubuntu1~18.04) )

                建议您要不也烧一下子再换吧。

                  @veye_xumm 是重新烧写nx的系统镜像吗?

                        之前你提的现象,主要是Image没有生效,跟dtb还不是一回事。
