Can we remove these redundant directories to reduce the size ? 35007 1 jessica.zhang 2013-07-26 19:19:49 +0000 Hi Yi, This is meant to be this way. If you choose to use the populate_sdk option to go with build toolchain, that means you want to have target image library files to go into your toolchain sysroot directory. Otherwise, you can just build the toolchain and extract target image rootfs as your sysroot. toolchain + sysroot is fundamental for cross development. The gmae is legacy for including certain target libraries but it doesn't match your target image rootfs at all.
