As for memory, it was: real memory =3D 251428864 (239 MB) avail memory =3D 221073408 (210 MB) until I've replaced existing u-boot with one provided in the wiki - https://sourceforge.net/projects/rpi4-8gbram-boot-fbsdonly/files/u-boot.b= in/download : real memory =3D 7700508672 (7343 MB) avail memory =3D 7487938560 (7141 MB) Thanks to Robert Crowston and all who work on this, well done.
