So far as I know: ) There is no FreeBSD supported U-Boot for any of: RPi5B CM5 (now orderable too) Pi500 (not yet orderable but there is a *.dtb now) ) There has been no FreeBSD kernel work for any of those. ) Together, the above 2 mean: no official support. ) Those of us using RPi5B's (only) via FreeBSD are using Release 3 of the EDK2 that one can get to via: https://github.com/worproject/rpi5-uefi?tab=3Dreadme-ov-file ) I'm not aware of EDK2 support for the CM5 or Pi500 at this point. ) If I understand right, FreeBSD does not support modern RPi* *.dtb's and RPi* firmware even for the RPi3B and RPi4B and related. (But I've done no testing of such in modern times.) ) The https://github.com/pftf/RPi4/?tab=3Dreadme-ov-file EDK2 for the RPi4B has an error that FreeBSD now handles via a panic. There are other issues (known before the changes in the error detection/hanndling) that make USB I/O to file systems corrupt data at times unless the 3 GiByte (or less) limit is imposed. (Duplicating sufficiently-huge files appeared to always end up with corruptions, for example.) So only U-Boot-based was working reasonably. ) The EDK2's tend to require specific *.dtb versions as well, but include such in what they bundle with the EDK2 materials. I do not remember the FreeBSD materials ever saying much explicitly about what FreeBSD does not officially support at all, which seems to be the RPi5B / CM5 / Pi500 status. I'm not aware of any developer claiming any stage of support or to be developing such for any non-personal/public use. The "so far as I know" status may well limit the accuracy of the above. =3D=3D=3D Mark Millard marklmi at yahoo.com
