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 ??

Thanks for the info, Hiroshi.

Retry to send NFS packet before reaching timeout.
