Texas Instruments TMS320DM357 DVEVM v2.05 manual Switch user to root on the host Linux workstation

Page 39

Installing the Software

3) Switch user to "root" on the host Linux workstation.

host $ su root

4)Perform the following commands to create a copy of the target file system with permissions set for writing to the shared area as <useracct>. Substitute your user name for <useracct>. If you installed in a location other than /opt/mv_pro_5.0, use your location in the cp command.

host $ cp -a /opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/target/* .

host $ chown -R <useracct> opt

5)Edit the /etc/exports file on the host Linux workstation (not the exports file on the target filesystem). Add the following line for exporting the filesys area, substituting your user name for <useracct>. Use the full path from root; ~ may not work for exports on all file systems.

/home/<useracct>/workdir/filesys *(rw,no_root_squash,no_all_squash,sync)

Note: Make sure you do not add a space between the * and the ( in the above command.

6)Still as root, use the following commands to make the NFS server aware of the change to its configuration and to invoke an NFS restart.

host $ /usr/sbin/exportfs -av host $ /sbin/service nfs restart

Note: Use exportfs -ravto re-export all directories. Use /etc/init.d/nfs status to verify that the NFS status is running.

7) Verify that the server firewall is turned off:

host $ /etc/init.d/iptables status

If the firewall is running, disable it:

host $ /etc/init.d/iptables stop
