CCS/TM4C123GH6PM: Unable to debug C++ application

Brian Savage

Part Number: TM4C123GH6PM

Tool/software: Code Composer Studio

I have a C application that I ported to C++. I am trying to debug the application, but the CSS debugger doesn't stop at the main() . The red STOP icon is available, but the pause button is not. I have tried adding breakpoints, but it does not stop at the breakpoints either. I have no issue debugging a C program. I am not even sure it's actually loading and starting at this point? Can anyone provide some guidance on debugging C++ applications??

Using a TM4C123G eval board.

Thanks!

Hi,

Depending on what is enabled (exceptions, iostream, template classes, etc.), the C++ application may require much larger stack and heap sizes to properly work. Apart from that, there is no difference in debugging a C or a C++ application from the debugger's standpoint.

In any case, the property of running automatically to main() is is set by the Auto Run and Launch options of the debugger. Please check:
software-dl.ti.com/.../sdto_ccs_debug-handbook.html

By disabling this option you will be able to assembly step starting from the entry point _c_int00 and find where the code may be throwing off your processor.

Hope this helps,
Rafael

Starterware/EK-TM4C1294XL: Inclusion of C++ libraries causes the PC to jump to Fault ISR even before entry to main has some measurements on the stack and heap requirements to be able to get to main when iostream is used.
