The most commonly used build version is arm-linux-gcc-3.4.1 and arm-linux-3.3.2, now embedded development basically use these, 3.4.1 is used to compile 2.6 kernel, and 3.3.2 is commonly used to compile busybox, if the compilation version does not work well with bootloader (u-boot), errors may occur. Therefore, you must select a compiled version. If this version d

What is a cross-compilation toolHttp://elinux.org/Toolchains to explain the cross-compilation tool, we first need to understand three basic concepts:
Compile platform: Refers to the platform on which the compiler is compiled
Compile host: on which platform the compiler runs
