What it won't do = (what was > always the case) is boot after I modify config.txt in any way at all. . . . Mine too, for how I did things. My previous notes about not being able to boot when modern eeprom content is present and modern rpi firmware is also present on the USB3 SSD did not cover having the indirection of pulling the FreeBSD kernel from the microsd card and having the FreeBSD kernel be what first gets to the USB3 SSD. But what I actually did eventually was have FreeBSD's kernel be the first thing that gets to the USB3 SSD. (Requires that the microsd card with rpi-firmware and u-boot on it has priority when present.) The USB-MSD aspect of the various rpi updates is not required at all for what I did. This also avoids u-boot needing to be able to deal with the xHCI or drives that involve xhCI use generally --but requires the use of a microsd card. (Not that I think u-boot requiring old, beta rpi-firmware is good as a long-term context.) =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
