I did on a panda board. It has the same problem and this patch solves it. So
this is not board specific problem. Please consider to change global setting of
NFS_TIMEOUT in nfs.c.
I hope someone else tries nfs command on the other board.
Following is the detail I did:
The default config of pand board disables NFS command.
So add this line in omap4_panda.h
#define COFNIG_CMD_NFS
(This line must be after #include configs/omap4_common.h>
I had trouble to use network on a panda board at the source from u-boot master
git.
Instead, I used source code from Linaro git.
(I think this is another issue. Just focus NFS timeout now.)
Before applying the patch: error occurs like this.
