From: Rachit on 5 May 2008 09:00 Hello, I am working on TMS320C54x platform.I am using Code Composer Studio 3.1 to develop application. How to check run time stack usage on CCS?Is there any other utility for this? Thanks, Rachit Shah

Hi Rachit, There's a very simple technique to do this. In your initialization (before the stack is first used), write some known bit pattern to the entire stack, like 0xDEAD. Then after running your application for some time in a representative or worst-case operating scenario, halt the debugger, examine the stack memory, and see how many 0xDEADs are remaining. -- % Randy Yates % "She has an IQ of 1001, she has a jumpsuit %% Fuquay-Varina, NC % on, and she's also a telephone." %%% 919-577-9882 % %%%% <yates(a)ieee.org> % 'Yours Truly, 2095', *Time*, ELO http://www.digitalsignallabs.com

Actually I want to check for stack usage by individual function at run time? Thanks, Rachit Shah

Do you know about this?How to use this on CCS? Thanks, Rachit Shah |
