Other Parts Discussed in Thread: MSP430F5659

Hi,

I am working on MSP430F5659 controller using Code composer studio 6.1.1 editor and TI RTOS.

I am trying to Turn ON LED in my project, it works in debug mode, but in Release mode LED is not at all turning ON.

I checked project setting for optimization, its same for Debug and Release.

What could be the issue here?

Issue/Problem happens only one of the Port Pin, Rest all LED's are turning ON without issue.

Please let me know how to resolve this.

Nitesh,
there are already threads in this forum with a similar problem. Can you tell us which compiler are you using? Can you also post the complete compiler command lines for your main source file for both the debug and the release build?
Here are some of the threads with similar problems:

Thanks

Without seeing the command lines for the both versions of the project and the actual code it's hard to guess what the problem is. Any extra code left to support debugging might change the timing between various events in your program. You can try varying various time intervals in your code when building in the release mode, and see if that makes any difference.

I am not using command line here, i am windows platform with CCS for compilation and editing.

i am using TI RTOS version - 2.14.3.28

Code Composer Studio 6.1.1.

Compiler Version v4.4.5 for MSP430 family

Is there any special settings i have to do if am making release build?

Since i am seeing my debug code works even if i remove the debugger and Release code wont work if i terminate the debugger?

In CCS, when you clean and build a project, the command lines for the compiler and the linker are shown in the command console. One of the buttons in the top right corner is "Copy Build Log". Please copy and post logs for both debug and release builds. I am hoping to see if there are any differences in build options.

I can't download the attached files. You should probably post the content as zip files unless you already tried that, or just post the output as inlined text.

It seems that the only difference between two versions of your project is in the optimization options "-O0 --opt_for_speed=0" applied to the Release configuration. I am assuming that there are no optimization options in the file configPkg/compiler.opt, which is present in both configurations. If that's the case, "-O0" should not matter because it's a default optimization level. The option "--opt_for_speed=0" will make your code smaller but slower. If you compare the map files for both projects, you would probably see that some functions became smaller. Look into what these functions do and if slowing them down can change a sequence of events in your code.
I know it's a very generic advice but that's the best I can do without actually debugging your code.

Hi Sasha,

Ok, that sounds god for me.

But can you suggest which is the best optimization i can use for the release build?

The best optimization setup really depends on what's important for your code, code size or execution speed or availability of the debug information or something else.
But, the fact that your app is not working properly in the Release configuration hints that you have a bug that gets exposed under certain conditions. Just because your Debug configuration works in your testing setup, it doesn't mean it will work under different circumstances with different timing of interrupts, etc.
I would recommend finding the bug first.

Sasha,

I understand, But GPIO high and Low is not working for us in release mode. Is it something where code is optimized and it is not executed.

Thanks and Regards,

Nitesh

It's possible, but I can't really know. You would have to find the code that differs between those two configurations and look for clues there. The best place to start is to compare map files generated by the linker and look for functions whose size changed.
