Difference between with emulator connection and without emulator connection.

Started by prathyush kumar August 30, 2005
hi to all
I want to know the reason for a simple question.
I am using XDS510PP Jtag emulator in my project.So when i connect this emulator to my target board i can run the Dsp only if i open my project in code composer studio (Texas instruments) and give a run from there.
But i am able to run the Dsp if i just turn on the power supply without connecting emulator.
I want to know the reason for that. What is the difference between with emulator connection and without emulator connection.
What is happening with in the hardware?
Please give me a suitable answer.
regards
prathyush


Hi,
By just connecting the emulator to your target board shouldn't stop the DSP
from running. Usually the target board knows the presence of the emulator
only when you start the code composer studio. When you take the code
composer studio, the emulator halts the DSP and takes control.
I believe either your target hardware has some problem or you have not
properly set the reset vector, and hence the DSP is not running properly
after giving power (i mean you only feels that its not running). Are you
loading your project (the .out file) from CCS before runnning it?
Cheers,
Ajith.
