Local static variable's address is wrong is CCSv5

Other Parts Discussed in Thread: TMS320VC5505

Hello,

Local static variable's value was wrong in express window. It's struct variable and when declared as file scope showed right value.

And I checked symbol address in module window. It shows different address with map file.

I'm guessing that wrong symbol address caused wrong value display.

M4 core and CCS5 is in use. Compiler is TI arm compiler 5.2.4.

Is there patch for this?

Best regards,

Wilson.

Hi Wilson,
Can you provide a small test case? Just a small project with source and executable would be great.

Thanks
ki

You may be encountering a problem where the compiler generates the incorrect address in the debugging information for a local static variable. See https://e2e.ti.com/support/development_tools/compiler/f/343/t/335888 for a potential work-around of compiling with --common=off

Thanks Chester.
I'll recommend --common=off work-around.
Best regards,

Hi all,

I have the same issue using a TIC5545 wit compiler version V4.4.1. i tried to include the flag --common=off to the build process but this is not supported by the compiler, is there another falg i can use?

Jorge,

Thanks in advance for your help.

Can you post an example project which demonstrates the problem?

I think you are encountering a different problem, since I ported my examples for the MSP430 v4.2.3 and ARM v5.1.5 compilers to the C5500 v4.4.1 compiler and haven't been able to re-create the problem.
