Scrolling Disassembley window interrupts DSP

Started by joseph_lyons_79 October 27, 2004


Hi all,

I have a C6711DSK with CCS 2.10.00. I have a program which processes
a signal from a ADC and sends the result to the DAC on the same
Codec. I notice that when I monitor the output of the DAC on a scope,
the output signal is interrupted when I scroll the disassembly window
in CSS. That is, the window that pops up when you load your program.

How can I load and execute my program with CCS, without there being
any other types of communication between CCS and my DSP?

Is it possible to switch all logging off? I've noticed LOG_system
can't be removed.

Cheers,

Joe.




Hello Joe,
 
The 671x devices use "stop mode emulation".  What this means is that anytime that CCS wants/needs information [like reading new instructions to disassemble] the DSP is actually halted [for a long period of time in the real time world].
 
I have used two methods to get around this:
1.  Load your program and close all CCS windows.  Hit run when you are ready.
2.  If you are taking real time measurements and don't need any of the 'debug stuff' [like breakpoints], you can execute your code using 'Debug->RunFree'.  This causes CCS to be effectively disconnected from the target [if you have breakpoints set, they will be ignored].
 
Both of these methods appear to not incur any 'CCS intrusion'.
