1、busybox
busybox is the lightest
1) Modify Makefile
CROSS_COMPILE ?= /usr/local/gcc-linaro-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-
ARCH ?= arm
2) 配置make menuconfig
Busybox Settings --->
[*] Build BusyBox as a static binary (no shared libs)
(/usr/local/gcc-linaro-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-) Cross Compiler prefix
3) Compile, install
#make
#make install
4) Copy the glibc library that Linaro Toolchain depends on
at https://releases.linaro.org/components/toolchain/binaries/latest/arm-linux-gnueabihf/
Find sysroot-glibc-linaro-2.25-2017.11-arm-linux-gnueabihf.7z, copy the usr and lib directories to the file system
5) Make a bootstrap file
slightly
2、buildroot
I use atmel sama5d3, it is enough to read this document How to build Buildroot for AT91
http://www.at91.com/linux4sam/bin/view/Linux4SAM/BuildRootBuild
This is a custom buildroot, and the general version usage is similar.
3、openwrt

Linaro Toolchain
Linaro provides monthly GCC source archive snapshots of the current Linaro GCC release branch, as well as quarterly releases of pre-built Linaro GNU cross-toolchain binary archives.
The following tables provide direct access to the most common Linux and bare-metal ABI variants of the Linaro binary cross-toolchain quarterly releases. Both x86_64 Linux and Mingw32 (MS Windows compatible) host binaries are provided:
