I have successfully booted linux via TFTP with root=/dev/hda1. I log in as root and navigate to /opt/dvsdk/dm6467. From there I follow the GSG instructions to run the demo as follows:
Target $ cd /opt/dvsdk/dm##
Target $ ./loadmodules.sh
Target $ ./interface
Then I receive the following error:
Interface Error: Failed to create display device instance
My bootargs are as follows:
DM6467 EVM > printenv

Also I noticed when the linux kernel boots, I get the following errors:
...

adv7343 1-002a: Error initializing

Not sure if this is related yet. Any help would be greatly appreciated regarding getting the "interface" demo to run.
