Part Number: LAUNCHXL-F28379D

Hello,

I want to integrate an assembly function in my project.

I looked at the C compiler User's guide, and found some explanation. I tried to do the same example as describe:

- my project contains a asm file:

- this asm file contains only one function: _asmfunc

- I declared this function as extern in the C file, where I have touse this function:

But this does not work. The compiler cannot build the project:

Can somebody explain to me why ?

Also, why does not the assembly function need to know the section where the code has to be written ? (I thought the the line .sect ".text" had to be added)

Thank you for helping me.

Hi,

Are you using EABI/COFF format? In case of EABI, you need not add '_' to the function name.

If you are using COFF, please ensure the .asm file is included in the build.

Hello, Thank you for answering me.

Yes, I use the EABI format:

I suppressed all the underscore, for the name of the function, and for the global variable. The compilation is OK (but I can t verify the result because of another problem, I cannot watch the expressions)
