hi all
where i may install bsd on orange pi zero?

You can research into this. I believe this would be correct installer. openBSD will release 6.2 in a few days. Maybe good?

Seems little awareness of BSD?  www.openBSD.org  https://ftp.openbsd.org/pub/OpenBSD/6.1/armv7/INSTALL.armv7

not sure freebsd has image.  

it need compile and send image to sd-card

any body try https://www.freebsd.org/platforms/arm.html
compile it ?

Better go for NetBSD.
