Compiler/TM4C123GH6PGE: Source code for _c_int00 available? Specifically, the TM4C123GH6PGE?

Part Number: TM4C123GH6PGE

Tool/software: TI C/C++ Compiler

I've searchws the forms and googled for the "_c_int00" reset handler source code and have found a plethora of questions about the address of the function, but thus far no source code. Furthermore, I have search through the c:\ti (including ccsv7 subdirectory) for the source with no luck. I would like to read through and learn how the processor is startup up. So, can anyone tell me if the source code for _c_into00 is avaialble for the TM4C123GH6PGE processor?

Thanks in advance,

Dave

    It depends on which version of the compiler you are using. For v16.9.4 it is in the assembly file "boot.asm" typically found here:

    C:\ti\ccsv7\tools\compiler\ti-cgt-arm_16.9.4.LTS\lib\src

    For version 17.6.0 it is in the file boot_cortex_m.c typically found here:

    C:\ti\ccsv7\tools\compiler\ti-cgt-arm_17.6.0.STS\lib\src

    Thanks so much Bob. That was what I was seeking. I can see now that this directory is what is compiled into lib.a and linked in with the project.
