I have some BananaPi and whole bunch of other boards but did not try FreeBSD + embedded development on them yet :-) > 1.) /usr/ports/devel/gcc-arm-embedded is marked as broken for aarch64.

Maybe this is related to my memory/swap note, below? Please report that on https://bugs.freebsd.org/bugzilla/ maybe someone with proper hardware and some time may verify. I wonder if adding big swap (i.e. 8GB+) will fix the problem :-) > 2.) There appears to be a name space conflict in /usr/ports/openocd/work/= openocd-0.10.0/src/target/nds32_tlb.h over PAGE_SIZE_4K, and the redefiniti= on breaks the build.

Super cool :-) If we have those two above fixes in the upstream so its "fire-and-forget" for everyone we will put that info on the WiKi :-) --=20 CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
