Third Party Demo output

I am experimenting with the third party demos that are supported with the encode/decode demo the dm6467 is preloaded with. I was able to make a tarball that the board correctly opens and executes, but I don't see any output. I tried using app.sh to just echo some text, but all that happens is the main demo interface exits and there are no errors on the command line. I also tried running a simple C program that output some text (which I know works since I've run it by itself on the board) and that had the same results. Finally, I tried using app.sh to touch a file, to see if it was doing anything at all, and yet again got the same results. I checked the tmp folder where the tarball is unzipped to see if it put it there, but it didn't. How do I print stuff to the video output device on the board, and why am I not seeing anything on the command line either? Are there any example third party demos that I can look at? Thanks.
