TMS320F28069: How can you change the name of the entry function "main()" in code composer studio?

Part Number: TMS320F28069

Tool/software:

Hello,

I wish to change the entry main function from this:

void main(void){

return 0;

}

to this:

void application_main(void){

return 0;

}

However, if CCS does not find a function with the specific name "main", it returns errors. 

What settings do I need to set to perform this change? 

Thanks.

    Hi Valeri,

    1. You have the option to change what symbol to run from when DEBUGGING. 

    Tools > Debugger Options -> Auto Run and Launch Options -> Auto Run Options -> change run to symbol 'main' to 'application_main'

    2. However this will NOT apply to your run time application code. I have looked into being able to change main to another name and use that new name. However because of our compiler you are not able to change the standard C name of the main() function.

    Please have a look at this thread: https://stackoverflow.com/questions/3974796/in-c-main-function-is-the-entry-point-to-program-how-i-can-change-it-to-an-oth

    Hi Ryan,

    Are you saying it is impossible to rename the standard C main() function specifically in CCS? I've seen it been done in Keil before with custom startup files, could you not do the same in Code composer? 

    Thanks,

    Valeri.

    Edit: 

    I have solved my issue. The CodeStartBranch.asm file calls to a file called boot28.asm with default settings. What I did is I linked that file to my project directory, changed all relevant sections named "_main" to "_application_main" and that compile my code without any errors. CCS now looks for "application_main" instead of "main". This link helped me.

    I just have one worry if this change will cause any problems. Can you confirm?

    Hi Valeri,

    This should not cause any problems as long as your application branches to your new "main" function code.
