You /can /do it with the base "nanobsd" tools in the source distribution = but Crochet is IMHO the better environment for the Pi series.=C2=A0 You=20 definitely want, in such an environment, a "runs with everything mounted = r/o EXCEPT volatile data which is on ramdisk or similar" as there is=20 severe risk of unbootable damage to SD cards if you take an unsolicited=20 power loss. I've been doing this for several years now and while there are some=20 quirks with Crochet on the RPI3 series at the moment due to unfortunate=20 issues with both the loader and the u-boot package both are things you=20 can work around and, at least for u-boot, you have to no matter how you=20 decide to build the image. Right now my embedded stuff is on 12.2 but I am looking at moving it to=20 13.x, probably after 13.1 drops. Straight "nanobsd" works just fine for the AMD-based pcEngines boards; I = have a bunch of those out in the field and they can properly exploit the = dual-partition property which is nice as it means they can be updated=20 "in place" and then rebooted into the update without doing anything=20 particularly fiddly. --=20 Karl Denninger karl@denninger.net <mailto:karl@denninger.net> /The Market
