This made it boot successfully! Obviously the boot spilled a bunch of errors, most just because I'm testing not connected to the network and the configuration expects networking to be available, but this is just a test. Really thanks a lot, this piece of information never turned out in any searches I did and I did not notice it in any man page/README etc. In fact I think this should be documented, if it is not already. Do you know if it is already in some manual page or readme or at least the wiki? If not I think it should be described in loader.efi(8), I'd like to propose a patch to this effect. Maybe also add a note in our wiki in the arm and/or uefi pages. Have you got some pointer to some documentation elsewhere about this so I can write an informed paragraph for the man page about this? >> >> I have reworked my scripts to replicate how the official release >> images are made in structure.

Yes this was the key to making it work. Maybe if I used a gpt partition scheme it would have worked OOB, while mbr requires this kind of help. Not sure if it is worth using gpt or could cause even more issues though. >> >> >> It gives me a prompt, but even if I do have a working USB keyboard >> plugged in I am unable to interact (maybe this is normal at this stage?) > No idea, sorry. Keyboard works fine once kernel starts, looks like a u-boot issue.

Yes I'll adapt my nanobsd update script to take advantage of the .env file and I should be ready to go. I'm actually skipping the grow part, since I'm never writing to the OS partitions, I'm using them like a firmware, only writing to the cfg partition (or the ramdisks obviously). > > It looks like you have that organised properly. > Thanks a lot again for your help! Really appreciated. Cheers! -- Guido Falsi
