C6455 Flashburn & RTDX

I am using a C6455 DSK board in a university project in which a DSP
application needs to communicate with C/C++ software on a PC in Linux.
I have tried RTDX but am having difficulties. I also haven't been able
to load the application to the board's Flash memory in order for it to
operate independently.

1. Is there an efficient way to load the application to non-volatile
memory so that it will run on reset, without having to write a
secondary bootloader?
2. Is there a simple way to establish data transfer between the board
and PC applications without having to run CCS? Will EMAC be a good choice?

I believe that the 6455DSK comes with a tool from SD to program the flash.
The so called 'Flash boot' on a 6455 just executes from Flash -
fetching everything 8 bits at a time - very s-l-o-w.
You will probably want it to copy itself to RAM for performance
reasons - OR just put an ethernet boot loader in flash an boot it that
way. It would be much less hassle [I think that TI has an ethernet
boot loader at ti.com].

I would definitely use ethernet - unless you want to venture into RapidIO.
