Xavier AGX Jetpack4.6不能刷入MPI327相机驱动

[wudecao]

AGX+原装0001主板，刚刚使用SDK Manager刷入的4.6系统，什么软件都没有安装
写入Image等3个文件到boot，并添加FDT命令，但无法找到驱动，
降级为4.5.1则驱动刷入正常

这是4.6系统的刷入截图

更奇怪的是把boot文件夹改为boot.old后系统仍能启动，怀疑是4.6系统的双rootfs功能启动了

但无论如何都无法刷入驱动，刷4.6安驱动失败，降级4.5.1安驱动成功，再次刷4.6安驱动，还是失败，（都是下载的对应版本的Image文件，具体可见图中的md5sum），搞了10多个小时了，精疲力尽

@wudecao
您好，如之前讨论过，你的操作是没问题的。而且你的系统中/boot/删掉都可以正常启动，很可能是jetpack4.6新的机制——rootfs冗余机制引起的。
请参考一下nVidia的文档：
https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-3261/index.html#page/Tegra Linux Driver Package Development Guide/rootfs_custom.html#wwpID0E06E0HA

进一步排查一下，期待update进展。

@veye_xumm我查阅资料，并使用命令：

sudo nvbootctrl -t rootfs get-current-slot

提示双rootfs并未开启（默认是不开的，需要手动配置），目前不知道删除boot还能正常启动的原因

@wudecao
这个问题暂时我没有思路。你如果愿意，可以把你的agx寄到我公司，我尝试追踪解决一下。
私信我，会给你邮寄地址。

@veye_xumm 已解决，使用host PC方法刷入固件，更新成功。Jetpack 4.6包含rootfs的备份隐藏分区，需要在host PC上使用flash -k命令才能同步更新隐藏分区。

@veye_xumm Oh No！出现错误

@veye_xumm 但是，虽然报错。
使用命令：gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! "video/x-raw(memory:NVMM),format=(string)UYVY, width=(int)1920, height=(int)1080" ! nvvidconv ! "video/x-raw(memory:NVMM),format=(string)I420" ! nvoverlaysink sync=false

相机是能够工作的...

@wudecao
这个不能算是错误，因为你并没有插入6个摄像头。所以会提示有的摄像头检测到，有的检测不到。
