CCS/TMS570LS3137: Could not able to load the file after changing the function name _c_int00

Tool/software: Code Composer Studio

Hi,

In my project i wanted to change my startup function name from _c_int00 to c_int00.

For this i have modification i change the following files:

1.sys_startup.c and sys_startup.h

2.sys_intvecs.asm

and while linking i am providing the starting address with lag option -e c_int00.

As per this changes, i can compile it correctly, just getting the warning,

entry-point symbol other than "_c_int00".

But i am not concern with the warning, as it can be suppressed.

But the main issue is when i am loading this Object file on the target,

I stucking into the Data abort exception.

While debugging,

I Found that during the stc_self_check(); it is causing this exception, and more of when i loaded i found that

at starting it is pointing to some other instruction than the init_core_register method as shown in below image.

But for the same files if i modified it to the _c_int00, it works fine, with starting, pointing to the init_core_register method.

So, Is there any additional changes required to make it work?

Please Help me in this issue.

Quick Response appreciated.

Regards,

Shivam Kakad

    In the TI ARM compiler RTS library, the symbol _c_int00 is defined in either the source file boot_cortex_m.c or boot_non_cortex_m.asm, depending on which ARM CPU family is used.  But you are using these files ...

    1.sys_startup.c and sys_startup.h

    2.sys_intvecs.asm

    What TI SW package do those files come from?  You need help from experts on that package.  Once I know the package, I'll notify those experts.

    Thanks and regards,

    Hi George,

    I have generated this files from the HALCOGEN, that i have shown below.

    But as i mentioned, I wanted to change the name for this startup function.

    so i changed it in the respective files I mentioned.

    The files boot_cortex_m.c or boot_non_cortex_m.asm which mentioned , that nowhere i am getting.

    My more concern is, why am i not able to point to the starting point of this function if i changed the name?

    Can you please provide me your inputs?

    Thanks,

    Shivam

    Hi Shivam,

    In addition to the HALCoGen Generated files, please also try changing the symbol _c_int00 in the boot_non_cortex_m.asm which is available in the following path : ..CCS_Install_Path\tools\compilers\Compiler_version_used\lib\src.

    I'm unable to replicate this issue at my end. Could you provide more details on this?

    Thanks,
