buildroot

I am trying to build a buildroot with kernel image, and after doing make menuconfig and make , I am getting: No kernel defconfig name specified, check your BR2_LINUX_KERNEL_DEFCONFIG setting I can set a string to the defconfig , but I don't know what to put there. My target system is an AT91SAM9RL board. edit : I found out there are some pre-made config files to some devices, actually not exactly matching to my target. You can issue the default configuration process by running make xxx_defconfig and that make target is a file in the folder arch/arm/configs/ . These default configurations are

详情请参考： http://www.buildroot.org/downloads/manual/manual.html 参考博客： https://www.cnblogs.com/arnoldlu/p/9553995.html Buildroot是一个为嵌入式平台构建一个完整Linux系统的工具，它可以生成交叉编译工具、文件系统、Linux内核和bootloader。 目录结构 ./buildroot$ tree -L 1 -d . ├── arch 目录存放CPU架构相关的配置脚本，如arm/mips/x86 ，这些CPU相关的配置，在制作工具链，编译boot和内核时很关键。 ├── board 存放了一些默认开发板的配置补丁之类的。 ├── boot ├── configs 放置支持的开发板的默认配置文件。 ├── dl 存放下载的源码包及应用软件的压缩包，第一次下载后，下次就不会再去从官网下载了，而是从dl/目录下拿开源包，以节约时间。本身下载通常都是很慢的，你可以手动找到相关包下载后放到这里就OK了，make时会自动检测这个目录。 ├── docs 存放相关的参考文档。 ├── fs 放各种文件系统的源代码；fs/skeleton：放生成文件系统镜像的地方，及板子里面的系统。 ├── linux 存放着Linux kernel的自动构建脚本。 ├── output

I am confused about some directories in rpmbuild. 1: buildroot: which should be used to store the files that are supposed to be installed when the binary package is installed by an end-user. Questions: how to control this directory? What does BuildRoot mean? $ cat 3.spec .. BuildRoot: /opt/abc .. %prep echo %{buildroot} echo $RPM_BUILD_ROOT whatever I set the BuildRoot to, I get the result which was defined in /usr/lib/rpm/macros . If I define %buildroot in ~/.rpmmacros , I will get the result from it. 2: How do I control the destination when we install the rpm package? For example: rpm -ivh

EDIT: This occurs when I am trying to use a separate partition with ANY mount point, not just /var . I am using Buildroot to build an embedded linux system. I am trying to use a separate partition for /var, but this occurs for ANY mount point. My init system is systemd, udev for device management. I've edited my fstab to: # <file system> <mount pt> <type> <options> <dump> <pass> /dev/root / ext2 rw,noauto 0 1 /dev/mmcblk0p4 /var ext2 defaults 0 2 proc /proc proc defaults 0 0 devpts /dev/pts devpts defaults,gid=5,mode=620 0 0 tmpfs /dev/shm tmpfs mode=0777 0 0 tmpfs /tmp tmpfs defaults 0 0

The make command build all targets, the first it build toolchain then packages and then rootfs and images of rootfs (tar, cpio ...). To rebuild rootfs I usually use make clean and then make. The make clean command removes all and including toolchain. So the first my question is: Is there some way to remake rootfs without building toolchain? It takes a lot of time. Also I am building linux kernel within buildroot.
