Hi again
Brain Thanks for your reply.
About your point about MP/MC#.
My board is correctly starting up. I am also running a relatively complex
program and debugging it through emulator. Therefore, I think at this time
setting of MP/MC# pin is not problem (It is set to zero.)
Moreover, at this time at first I want to program the flash, so define it in
data space between 0x8000 and 0xFFFF.
I will be thankful if state your opinion.
Best Regards,

connect the data and address buses directly from DSP to the Flash memory.
Further, I make OE, WE, and CE signals of the Flash using MSTRB#, DS# and R/W#
signals of DSP.

Its been a bit since I touched a DSP, but I think you also need to have
the MP/MC line pulled the correct direction in order to boot from the
flash.
You might take a look at the bootloader app note for the C54XX family,
it covers all the different boot sources and how to make sure the
correct one is selected.
