[U-Boot-Users] NFS Timeout with large files.

[Hiroshi Ito]

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.
