Hi All,

I am trying to understand one problem which we have found.
The problem is that I can't on Microblaze little-endian platform
mount nfs without -o nolock options. (Log below)
Selecting tcp or udp has no effect.
I am using emaclite driver and there is no problem on big endian 
microblaze.

ping, telnet, http, ftp, iperf, netperf work well.

That's why I have a question if there is any endian specific option for 
NFS?

Thanks,
Michal

Where is rpc.statd? Without it, the above behaviour is 100% expected.
