All float-point operations are done in software not using the ARM hardware VFP. Correct ? If I want to build FreeBSD 11 with hard float support can I do this already ? Do we support hard float ? And how should I compile things ? # setenv ARCH armv6hf (is this correct ?) # make buildkernel KERNCONF=RPI2 Thanks, [1] http://download.raspbsd.org/FreeBSD-armv6-11.0-RPI2-286947.img.gz -- Stefan Parvu
