1. Do you have an emulator??  If yes, you can examine
the code loaded from Flash and step through it.
2. If no, do you have a 6713 DSK for reference??
3. If yes, does your code run correctly on the DSK??

As a start, I would suggest that you end your Flash
program with a 'forever' loop that Jumps between two
locations in Flash.  You can then check the address
lines [if you can access them] with your scope to
verify that the DSP if branching between the correct 2
locations.

We can provide more info once you describe the tools
and equipment that you are using.

Hi lion king

If you don't have an emulator how are you getting your code into your
board?  Could you post your schematics for us to look over?

The code I burn into flash has run correctly on the DSK.

reset is
configuring PLL. I has change dsk_init() function and call it from my
project. When I run my project on the DSK, ECLKOUT is configured
correctly as 80MHz. But when I change to my own board with
TMS320C6713BPYP, the ECLKOUT is still 25MHz ( the default value is 1/2
of CLKIN). So I'm sure my code hasn't run. Do you have any suggestion?

Hi, because I don't have emulator, so I burn my code into flash using
Universal Programmer to program hex code into flash.
