3) Go to the /restore directory.
EVM # cd /restore
4) Set the Linux date variable to today's date. If the date is too far off,
the target file system installation generates warnings for each file it
installs.
EVM # date MMDDHHMMCCYY
For example, for 9:00 am on April 18th, 2006, enter 041809002006.
5) Add execute permissions on the prep-hdd script.
EVM # chmod +x prep-hdd
6) Run the prep-hdd script in the /restore directory.
EVM # ./prep-hdd /restore
7) The script will ask for confirmation: "Are you sure you want to
partition and format /dev/hda1?" Type yes .
8) After the HDD restore is complete, shutdown the EVM:
EVM # halt
9) When the "Power down" message is printed in the terminal window,
it is safe to power down the EVM.
10) Restart the EVM and configure U-Boot to root mount via the local
HDD. Follow the steps in Section A.4.1, Booting from Flash Using the
EVM’s Hard Drive File System .
If you instead manually restore the overlay.tar.gz file from disk 1 on an
NFS file system, the demos will likely produce a cryptic error. Although
such manual restores are not documented or recommended, you can
correct the problem by turning off the s-bit as follows:
EVM # cd /opt/dvsdk/dm6446
EVM # chmod u-s ${install}/encode ${install}/decode ${install}/encodedecode \
${install}/interface
