I see. Sorry for the noise. I did not get that you had selected ubuntu from inside the RaspberryPi-imager User Interface. Another (implicit) bad guess at context on my part. In this case, my comments about the .dtb files not being RaspiOS based and not matching the ones that FreeBSD is based on using for RPI3 builds applies as far as I know: it is the same material as available from the ubuntu web site for installing 2020.04.1 . The notes about the vintages of start4.elf and fixup4.dat predating 2020-Aug-20 by a notable amount also applies. It will be interesting to see if 2020.10 uses newer start*.elf and fixup*.dat materials when it is released later this month --as well what vintage of dts materials it ends up being based on. > Let it write to SD or USB=E2=80=A6 then mount the = ubuntu-msdos-partition and copy over the whole crap=20 > to your FreeBSD-USB-boot-media for the 4GB-model =E2=80=A6. > enjoy to see FreeBSD booting from USB without SD_card =E2=80=A6 > Perhaps you will stop enjoying the greatful boot-process when it will = hang short before it initializes RobOCrow`s pcie-driver :-) Ha Ha > but it boots 2020.10 and that=E2=80=99s the first step before fixing = the hang... =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
