Hi,

I am facing a problem with U-Boot. Our NFS server supports NFS v3 and v4 but it seems that U-Boot is NFS v2 only.

Is there any plan to update to v3? Otherwise, I could help, but I would need some pointers to NFS protocol handling.

I'm not aware of anyone working on that. Maybe someone more familiar with NFS could help, or look at the differences in the Linux implementations.

I received a note from bodhi bodhi mibodhi@gmail.com that he is successfully using NFS v3 with modern U-Boot (since 2014).

Here are the details of the environment that he included...

I think he uses NFSv3 for the root filesystem but the NFS server is also NFSv2 compatible for u-boot nfs loads (uImage and DTB).
