You cannot do this so easy. First, the image is linked to a specific address; it is NOT position-independend. Second, the image expects to find writable data and BSS segments which fail when burned to ROM/flash.
How do I load a stand-alone application .bin onto flash after loading it into RAM? Secondly, how do I load and run "hello_world" (ELF) correctly? I know I'm missing something really basic here!
You can copy a stand-alone application to flash for storage; but to run it you will have to load (copy it back) to it's link address in RAM. If you want images which support XIP from flash you will need to twiddle the linker script a bit.
Also note that you can wrap your stand-alone application into a "Standalone Image" (image type IH_TYPE_STANDALONE) which would take care of (eventually uncompressing and) loading the image to it's start address.
