So far as I know, the FreeBSD kernel was only designed to handle the RPI-B for armv6. That in turn involves the RPI-B's firmware and U-Boot being involved before FreeBSD, not just FreeBSD. The RPI-B firmware might make live changes to the .dtb file contents that it loads. The RPI-B firmware is not arm code but some Broadcom code, as I understand. (Until more recent times, arm cores in RPi*'s were slave processors to the Broadcom video core hardware.) The more I think about this path, the more it looks unlikely to be readily used. > Mike >=20 >> On Mon, Apr 22, 2024 at 2:53=E2=80=AFPM Lexi Winter <lexi@le-fay.org> = wrote: >>=20 >>> Warner Losh: >>>> On Mon, Apr 22, 2024 at 2:30=E2=80=AFPM Lexi Winter = <lexi@le-fay.org> wrote: >>>>> after running 'make -C release NO_ROOT=3Dyes release' for = arm.armv6 i >>> have >>>>> the following files: >>> [...] >>>>> none of these appear to be bootable media >>>=20 >>>> IIRC, arm stuff was built by thermite and not the release script. >>>=20 >>> thanks, i guess that explains why i don't get a bootable media. >>>=20 >>> i'm trying to boot an armv6 GENERIC kernel under qemu to test my PR: >>> https://github.com/freebsd/freebsd-src/pull/1124 >>>=20 >>> could you recommend the best way to do this? duckduckgoing "freebsd >>> thermite" doesn't return any results that look relevant. >>>=20 >=20 =3D=3D=3D Mark Millard marklmi at yahoo.com
