Xilinx changed their default toolchain provided by XSDK to arm hard float in a recent version (v2016.1?). As such meta-xilinx also switched (krogoth and newer) to defaulting to hard-float as there was no longer a need to default to soft-fp for compatibility. You can read a bit about it here: https://lists.yoctoproject.org/pipermail/meta-xilinx/2016-February/001466.html > > The solution is to use the same toolchain for everything.

This is definitely recommended, you can build an "SDK" with Yocto if you need the toolchain for standalone development.
