booting from flah memory in c6713 dsk?

Started by joshy jose February 25, 2007
hai friends,
i wish to boot my appliction from flah memory , my intention is to make
work the particular application written in flash , when the supply is given
and reset the processor. how can i do this , as the default boot mode is
from flash, i hope that i need only to save the program in flash
by specifing in the location in .Cmd file.

if i am wrong then what the way to do this?

Joshy J,

On most TI DSPs, there is a boot rom that can be forced to execute upon
power-up or reset via the voltage state of certain pins during the reset sequence.
That boot rom expects a jump instruction at a specific address in flash that
jumps to the entry point of your program.
As part of burning your program into flash, that jump instruction also needs
to be burned into flash at the correct address.

I'm not sure of which pins need to be in which state for the c6713 DSK
to start at the build in ROM nor the exact address for the jump instruction.
Your TI manual and/or a search of the internet should expose the correct answers.

For DSK 6713, suggest to search on Spectrum Digital website for "Flashburn" utility. This page has some comments:

But be very careful: if you make an error it can be hard to return the DSK board to "normal" operation, since its
default mode is to boot from Flash and perform self-test functions (flash LEDs, etc). Study the material carefully
first, and one important advice: make sure you have a reliable, solid program running using CCS download before you
Flash.
