Please give me a way to run nfs server on embedded linux based on TI SDK.

I build kernel with NFSD kernel support, but what's next?

Hello,

I am wondering if you could please share which PSDK Linux you are using. Also, please refer to the following document as a reference for NFS setup.

Regards,

I am use tu-PSDK 04.03.00.05. I build linux kernel with NFSD support. Then i build nfs.utils tools vers 2.4.3.

I start nfs daemons: rpc.nfsd, rpc.mountd, rpc.statd. I create /etc/export.

But when i try mount from client i get error: cIntudp_create[NFSD]: RPC: Program not registered.

What happened?

Hello,

Sorry, I initially thought you were trying to perform a NFS boot but it seems like you are setting up a NFS server on the EVM. TI did not create the NFS tools and they are part of the open source software that get integrated in the SDK. I recommend you refer to the following links as a reference:

Krunal, thank you. My problem was using different protocol to nfs communication.

Client try using NFS over TCP, but server register only NFS over UDP.

To resolve i start nfs server with command line: "rpc.nfsd -u" - using UDP.
