修改配置文件:可以使用ROOTFS_POSTPROCESS_COMMAND参数来指定在构建过程中对rootfs进行处理的命令。可以通过编辑local.conf文件并添加自定义的命令来修改配置文件。 构建系统镜像:完成配置文件的编辑后,可以使用Yocto提供的构建命令来生成定制的嵌入式Linux系统镜像。运行构建命令后,Yocto会自动下载和构建所需的软件包,并将修...

进一步跟踪定位发现,所以IMAGE_FEATURES如果设置为read-only-rootfs那么fstab中将设置为只读。 1 2 # Tweak the mount options for rootfs in /etc/fstab if read-only-rootfs is enabled ROOTFS_POSTPROCESS_COMMAND += '${@bb.utils.contains("IMAGE_FEATURES", "read-only-rootfs", "read_only_rootfs_hook;...
在根文件镜像上运行的优化过程包括了mklibs, prelink和其他的后期处理命令,这些命令定义在ROOTFS_POSTPROCESS_COMMAND变量中。mklibs会优化库文件的大小,而prelink会通过优化共享库的动态链接来减少可运行文件的启动时间。 在根文件系统被构建好之后,对最终镜像的处理就会从do_image任务开始。构建系统会运行定义在IMAGE_PR...
在镜像中运行的优化进程包括mklibs、prelink和ROOTFS_POSTPROCESS_COMMAND命令变量定义的任何其他后处理命令。mklibs进程优化库的大小,而prelink进程优化共享库的动态链接,以减少可执行文件的启动时间。
ROOTFS_POSTPROCESS_COMMAND Added by classes to run post processing commands once the OpenEmbedded build system has created the root filesystem. You can specify shell commands separated by semicolons: ROOTFS_POSTPROCESS_COMMAND += "<shell_command>; ... " ...
2. Installing the scripts in ROOTFS_POSTPROCESS_COMMAND in the my image recipe that includes the core-image-minimal. I got some license checksum problem by doing this: ... ERROR: my-image-1.0-r0 do_populate_lic: QA Issue: my-image: Recipe file fetches files and does not have license ...
To remove them at a later action might be possible. like write <recipe>.bbappend which does remove work. What should I do in the bbappend file? Did you intend to use ROOTFS_POSTPROCESS_COMMANDS in the bbappend file? 0 Kudos Reply Post Reply About...
其中Buildroot功能强大，使用简单，而且采用了类似于linux kernel的配置和编译框架，所以受到广大嵌入式开发...
