Euan, To get the program to run automatically after startup you need to have a script in /etc/rc.d/rc#.d where # is the run level you are booting to. In the case of DaVinci # is run level 3. If you look at the /etc/rc.d/rc3.d/S88demo script on the DaVinci hard drive file system you will see that it is a copy of the dvevmdemo script in /etc/init.d
In fact, if you want your application to run at any run level the best thing to do is to put it in /etc/rc.d/rcS.d Another thing to note is that convention is usually to put the script that will kick off your application in /etc/init.d (like the dvevmdemo script) and then make a symlink in the proper rc.d directory to point to your script (do an ls -l /etc/rc.d/rcS.d for examples). The S## value, where ## is a number, indicates the order in which these scripts are run. The higher the number the later it is run. For your cast you should probably make it high like 89-99 since you want to make sure that everything else that your application might use is loaded first. Let me know if you have other questions.

Am I terribly mistaken?? So, are you able to load and run your app now?

And the script is located at /etc/init.d/ dir in your DVEVM file system. The app also is located somewhere on the DVEVM file system. With the above information, you should be able to figure out how to load and run you app automatically.

I'm sure this can be done as this is how the board behaves out of the box with the TI demo apps (encode, decode, encodedecode etc in the menu interface). how do I set this up for my app?

I now need to do some testing with a machine in another part of the site and I don't want to have to bring my host machine with me. What I want to do is have the DVEVM boot using my boot image that I created and then load my app once the boot has completed so that I don't need to have the DVEVM connected to my host. How can I do this? Currently the uImage I want to use is on the host PC hard drive in /tftpboot and my app I want to run is on the DVEVM hard drive in /opt/dvevm.
