It's a funny coincidence that the same question was asked just a few days earlier: https://lore.barebox.org/barebox/CAAvCNcByUskEuqLMPmO6mbCOZHhYNx_OXZKYO+HKyz_=Cs2RCQ@mail.gmail.com/T/#t Do you and Dan both perhaps use the same Enterprise Linux that now ships without UDP support in the kernel NFS server? To sum up the other thread: We don't have a TCP stack in barebox, but that's a hard requirement to do NFSv4. There's AFAIK no one currently working on this. The immediate options are either using TFTP to download the kernel and then use NFS for mounting the rootfs within the kernel or to use a userspace NFS server. I am using NFS Ganesha at home for this.
