问题描述及复现步骤:
本帖最后由 music1913 于 2022-6-22 15:24 编辑
在 firefly 的官方云盘中，可供下载的debian 10的文件包内容如下：
AIO-RV1126(1109)-JD4\Debian10\debian10_2021_0429_1902\debian10\
![]()
我将上述文件与路径 AIO-RV1126(1109)-JD4\Buildroot\AIO-RV1126_RV1109-JD4_IPC_2021_1206_1919\ 下的固件包先进行了合并，然后再通过RK_Dev_tool整体刷入主板的，所以最终的刷入主板的官方固件包结构是这样：
![]()
刷入后，主板系统启动后一切运行正常。在主板系统启动后，安装包括python的一些package, 各类配置文件等，通过pip install ... 和拷贝等方式，安装至系统中。
到手一个 32G 的U盘，插入windows pc, 下载 DiskGenius 将其 format 成 ext4 格式：
插入U盘至rv1126主板，并加载（映射）U盘至本地文件夹：
- sudo mount /dev/sda1 /media/usb_drive
2.导出当前固件
用工具 ff_export_rootfs 进行 export:
firefly@firefly:~/Download/ff_export_rootfs_buildroot$ sudo ./ff_export_rootfs /media/usb_drive/
MEDIA FREE SPACE SIZE 55975 MBytes
EXPORT IMAGE SIZE 8568 MBytes

find: '/proc/896/net': Invalid argument

sync finish
Export rootfs to /media/usb_drive//Firefly_ext4_202206170232.img Success
可见生成的文件Firefly_ext4_202206170232.img有file size达到9G。
压缩镜像文件：
- firefly@firefly:/media/usb_drive$ sudo /sbin/e2fsck -p -f Firefly_ext4_202206170232.img
到7G。
3.unpack官方固件
官方的未解离的固件文件存在于： AIO-RV1126(1109)-JD4\Debian10\shao_merge\pack\AIO-RV1126-JD4-BE-45-GPT-20211206-1919.img 将此文件重新命名为 update.img，并拷贝至一台安装了firefly-rk3399-linux-repack 工具的 Ubuntu PC机上，并运行
,可以看到运行结果：
shawn@DESKTOP-9NG0VFK:~/Downloads/firefly-rk3399-linux-repack$ sudo ./unpack.sh

在此 Ubuntu PC 上，可以看到 unpack后的文件夹位于： xxxx\Downloads\firefly-rk3399-linux-repack\output\Image\ 其中的文件结构如下：
将之前私有定制后export出来的Firefly_ext4_202206170232.img 重新命名为 rootfs.img 并覆盖替换上图中的同样文件(size 490.34M),所以现在文件夹结构为(其实仅一个文件被更换了)：
回到 Ubuntu PC 命令行中，进行重新（repack)打包：

得到文件结构：
将上述文件包刷入板子中：
因rootfs.img较大，此次写入需要10几分钟，完成后，通过串口连进去板子，看到如下错误，且系统进入了initramfs模式：

请问上述步骤是有哪里不对吗？
