I have started on the design of a stand alone board with a C5402. I have been
using the DSK up to now. Three aspects that I dont have clarity on:
1. The program for the DSP should be loaded from flash memomy. How does the
onboard boot loader work?
2. How will I program this flash module on my board
3. What sort of interface from pc to the DSP do I use as I will have to do some
code development on this board? I have a XDS emulator. Will that be suitable
and will I be able to program the flash with that?

For the bootloader take a look on TIs application report SPRA618A.
This report describes in detail the function of the On-Chip bootloader.

You can flash the FLASH ROM on your board with the FLASHBURN utility
supplied by TI with
CCS V2.0 or later. Take a look in the folder "\bin\utilities\FlashBurn"
there you will find further information.
But for that your have to write your own so called FBTC programm, to
interact with the FLASHBURN utility.

Yes it is possible. The only thing to do is to place a JTAG header on your
board like that you find on your DSK board.
