I use an usb ethernet = device and usb disk with the root filesysteem. Compiling and running = ports works, but a build world fails randomly with a memory access error = eg after running 15 minutes. Sounds possibly similar to TARGET_ARCH=3Dpowerpc 's stack-handling SVR4 = ABI violation when world is built by clang 3.8.0 (bad clang code = generation). To get to the point of buildworld going through I had to = change the kernel to provide a so-called "red-zone" on the stack during = signal handling to protect the stack from being trashed. buildworld gets = extensive signals (SIGCHLD) and so without the "red-zone" it would = eventually get trashed addresses, far before getting near completion. [Context: buildkernel via gcc 4.2.1 but buildworld via clang 3.8.0 .] [Side note: I've tried aarch64 releng/11.0 (first RELEASE's raw) under = qemu on Ubuntu 16.04.1 on the ODroid-C2 but it gots periodic illegal = instructions in very basic operation, no builds active.] > I don't think it makes sense to work on this until a freebsd rpi3 = arm64 port is officially supported...
