-
在firefly板卡中安装
fireflydev。sudo apt update sudo apt install fireflydev
-
在firefly板卡接上容量较大的移动硬盘（空间大于30G），使用
ff_export_rootfs导出根文件系统。sudo ff_export_rootfs /mdedia/firefly/your_dev/your_path
-
将生成的文件重命名为
rootfs.img。 -
在另一台PC上下载打包工具
firefly-linux-repack。 -
从官网下载固件，解压后名称改成
update.img，放到firefly-linux-repack路径下，执行解包脚本./unpack.sh，（注：RK3588需要RKImageMaker使用v2.0以上版本）。# 版本过低会报错： $ ./unpack.sh start to unpack update.img... ********RKImageMaker ver 1.66******** Unpacking image, please wait... Error:Check update.img failed! Press any key to quit:
正常输出如下：
$ ./unpack.sh start to unpack update.img... ********rkImageMaker ver 2.0******** Unpacking image, please wait... Exporting boot.bin Exporting firmware.img Unpacking image success.

解包完成后，
output/Image目录下会生成以下文件：
-
将步骤3生成的
rootfs.img替换掉output/Image/rootfs.img，然后执行打包程序./pack.sh。$ ./pack.sh start to make update.img...

完成之后会在
firefly-linux-repack目录下生成new_update.img，即为可刷机镜像。
注：
- 如果生成的镜像无法给新板卡刷机，可能是因为镜像太大了，删除部分无用的软件/库，重新生成
rootfs.img文件。
