I have my program made for working on Linux. However, now I want to configure the Linux in such a way that when i start the tiny6410 device, it will only open my program and when I close my program, the device will shutdown. When i am running my program, nothing of the Linux should be accessible. One more thing that I want to do later is to put a write protection on the SD Card where the software is loaded. Not the lock that is physically available on the SD Card but a selective write protection that will ensure that no one will be able to copy any files even if they are accessed from the USB stick.
