I have attempted this with two very different SD cards -- one Sandisk Ultra that previously had Kodi on it and was running in that specific Pi4 and the second is one that while slower is one of a dozen here of a series that have served me extremely well in Pis for a very, very long time. >> The builds on my box (and apparently the one on the FreeBSD official image page) are all using 2025-04 u-boot as the official FreeBSD load off the distribution page behaves exactly the same way -- the EFI loader boots without incident, gets and loads the kernel, the kernel boots as expected but the mmc driver takes timeouts and cannot see the sd card after the kernel comes up, thus root mount fails. > Summary: The below booted from a microsd card just fine > on one system --but not on another-- based on: > > FreeBSD-14.3-STABLE-arm64-aarch64-RPI-20250724-f0a7a1bda375-272016.img.xz > > It failed for a rather old 4 GByte RPi4B that I got access > to (older EEPROM content as well) --but worked on a modern > 8 GiByte RPi4B. Lovely. So from appearances there's a hardware difference that apparently results in this; this is an older one (quite old) which is the only "4" I have right now. I guess it get relegated to Kodi use (if ever); I'll see about sourcing some newer ones (whether I borked it when I updated its firmware as Kodi wanted or whether its rot somewhere in the FreeBSD driver code that breaks for this hardware but not newer stuff I don't know.) I'll play with some older u-boot copies I have laying around but since the EFI loader and then kernel starts I'll wager that ain't the issue and see about sourcing a couple of the newer ones to play with for the purpose I'm screwing with these in the first place. > === > Mark Millard > marklmi at yahoo.com > > -- Karl Denninger karl@denninger.net /The Market Ticker/ /[S/MIME encrypted email preferred]/
