EK-TM4C129EXL: C and assembly mixture

Hi Danilo,

The way you are calling the assembly functions appears correct. My only concern is with the RunPt variable you are referencing. Please, ensure you are following the guidelines documented here for interfacing Assembly and C code: https://software-dl.ti.com/codegen/docs/tiarmclang/compiler_tools_user_guide/compiler_manual/runtime_environment/interfacing-c-and-c-with-assembly-language-stdz0544217.html

Thanks,

Hello,

        This is the original creator of the question.  The only thing I noticed is that on line 64 of my .asm file, I had .word instead of .field.  Is that what you meant?  If not, I am not sure what else there could be.  It all looks the same to me.

Thank you

Hi Drew,

Is there a specific error you are seeing?

Thanks,

Hi Eric,

        No, there are no syntax errors, but there is a runtime error when I call my startOS() function on line 137.  My interrupt assembly functions appear to work well, but when I try to start my OS, I get a fault ISR.  I do not know if I am not seeing the interrupt assembly code not work correctly (as debugging never jumps to the assembly file), or if the attempt I have with the RunPt is still giving me a headache.

Thank you
