Hello, Upakul
I got same experience.
U-boot NFS command do not retry to send a command again. so, when the packet is lost, It will cause timeout.
with this patch, it should fix. but this is very old code. so, I don't know, it can applys to current one.

Hi all,
I am facing a timeout problem with nfs while transferring large files. However i encounter no problem with smaller files.
The entire thing works fine with another nfs server.
Any hints on what could be the problem ??
