Hi
Currently iam using the Hawk board OMAP L138. I downloaded Arago demo fs TAR from TI site.Iam finding below error messages

I downloaded the PSP also from the ti site "DaVinci-PSP-SDK-03.20.00.11"... I tried to use the kernel image in it... But it is not booting.so
i used the kernel in the nand flash by issuing command
nand read.e 0xc0700000 0x200000 0x200000
then boot from there using below command
bootm 0xc0700000
Regarding the exports,KIndly have a look after cat /etc/exports
# /etc/exports: the access control list for filesystems which may be exported
# to NFS clients. See exports(5).
#
# Example for NFSv2 and NFSv3:
# /srv/homes hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check)
#
# Example for NFSv4:
# /srv/nfs4 gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check)
# /srv/nfs4/homes gss/krb5i(rw,sync,no_subtree_check)
/export 192.168.1.0/24(rw,fsid=0,insecure,no_subtree_check,async)
/export/fs 192.168.1.0/24(rw,fsid=0,insecure,no_subtree_check,async,no_root_squash)
/export/kernel 192.168.1.0/24(rw,fsid=0,insecure,no_subtree_check,async)
/home/OMAP35x/filesys 192.168.1.0/24(rw,no_root_squash,async)
/home/OMAP35x/filesys2 192.168.1.0/24(rw,no_root_squash,async) -> This is the nfs fs to be mounted..
i followed as per below link
