Hi Community,
I have been trying with NFS the file system in my PhyCORE-AM335x PCB 1358.2
load. The Tools are used for this:
-OSELAS.Toolchain-2011.11.3
-BSP-phyCORE-AM335x-PD12.1.0
-Ptxdist 2012.03.0
-Barebox
____________________________________________________________
In the host the /etc/exports file has this configuration:
# /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)
#
#This is for sitara TI
# /home/ 192.168.3.0/225.225.225.0(rw,no_root_squash,no_subtree_check)
# /home/sst/sitara/targetNFS
*(rw,nohide,insecure,no_subtree_check,async,no_root_squash)
#This if for Phy-CORE
/opt/ 192.168.3.0/225.225.225.0(rw,no_root_squash,no_subtree_check)
/opt/phyCORE-AM335x-PD12.1.0/NFS *(rw,sync,no_root_squash,no_subtree_check)

the /opt/phyCORE-AM335x-PD12.1.0/NFS is where I descompresed the file root.tgz
