AWR1843: symbol "_c_int00" redefined after enable dynamic stack overflow check

Jun Han

Part Number: AWR1843

Hello,

When dynamic stack overflow checking is enabled in CCS, I am getting an compile error:

unresolved symbol handle_stkovf, first referenced in rtsv7R4_A_le_v3D16_eabi.lib<stkchk_t2.obj>

symbol "_c_int00" redefined: first defined in "boot.obj"; redefined in "rtsv7R4_A_le_v3D16_eabi.lib<boot.obj>" symbol "_c_int00" redefined: boot.obj"; redefined in "rtsv7R4_A_le_v3D16_eabi.lib<boot.obj>"

I have read many advices on the forums. The handle_stkovf issue has been resolved,but the redefinition issue still exists.

Thank you very much for your help

Hi Samhitha,

I am using Code Composer Studio 7.1.0 and the compiler version is ti-cgt-arm_16.9.6.LTS.

Hi Samhitha,

I don't use any examples but instead used my own code. I create the _c_int00 function.

If dynamic stack overflow checking is enabled in CCS， can I not use this function name? Should it be changed to a different name? For example, _ss_int00.

Hi Jun,

The function _c_int00 is the startup routine for C programs. It performs all the steps necessary for a C program to initialize itself. So, create the custom function with another name. For more information about _c_int00 function, refer to 8.3. Run-Time Initialization — TI Arm Clang Compiler Tools User's Guide.

I have another question. About the handle_stkovf function, is there an example code?

Hi Jun,

I want to confirm if you want to handle stack overflow using handle_stkovf function.

I didn't find any such function. I found the following thread - (1) CCS/TMS570LC4357: stack_overflow_check - Code Composer Studio forum - Code Composer Studio︎ - TI E2E support forums

Let me know if you need more details.
