And the next step is to make some changes to the kernel. I want to make some modules to serve this purpose. The freeBSD system ported to the BeagleBone somehow cannot make the module, it says cannot find the source tree. So I tried to make the module on the freeBSD 9.1 running on the virtual box 4.2.6. The virtual box runs on i386 PC. I tried to change into cross compile through:

The source code at projects/armv6 is very out of date; everything from
that branch was merged into head months ago.  Use either stable/10 or
head (best support is currently on head).

When cross-building for Beaglebone use TARGET_ARCH=armv6
