Is it possible to use NFS with built-in kernel on 5912 OSK?

Is it possible to use NFS with built-in kernel on 5912 OSK?

[Sergey Vointsev]

Hello, everybody!

I try to mount folder of host PC via NFS. From other PC it works
perfect. But from OMAP5912 OSK I have the following situation:

# insmod /lib/modules/2.4.20_mvl31-omap5912_osk/kernel/fs/nfsd/nfsd.o
# mkdir /tmp/nfs
# mount 192.168.0.16:/nfs /tmp/nfs
mount: 192.168.0.16:/nfs failed, reason given by server: Permission denied
mount: nfsmount failed: Bad file descriptor
NFS: mount program didn't pass remote address!
mount: Mounting 192.168.0.16:/nfs on /tmp/nfs failed: Invalid argument

What's wrong? I use standard kernel and rootfs shipped with the board.
By the way, why OMAP5912 OSK has 32M of flash onboard, but the size of
default rootfs is only 16M?

Thanks. Sergey.

Check your host setup in /etc/exports, maybe you have made some restricts of
ip.

Because the rootfs' address starts from 0x1000000.

Can we somehow use (make fs and mount) previous 16M?

Hi,

 Probably you can update the u-boot ver 1.1.2 or later, which 
allocates the file system from 0x00240000.
