Compiler/TMS320F28069: 28069 - Functions located in a different file called with zero arguments

Tomas Sadilek

Part Number: TMS320F28069

Tool/software: TI C/C++ Compiler

I have a function A located in file 1. This function is called two times in a function B located in file 2.

However, when function A is called, the input argument does not correspond to the parameter as set in function B.

What could be the issue? This code is obtained from an IC vendor - so it should presumably work without any modifications.

Thanks,

Tomas

B: the argument is 29747.

A: the input argument is 0.

For the files dp_if.c and main.c, please send in a test case as described in the article How to Submit a Compiler Test Case. I'll use that to generate the assembly code for the function Vpc3Read, and the two calls to it, and inspect that for problems.

Thanks and regards,

Make sure there is a prototype declaration for the function visible at the point you call Vpc3Read. As the function seems to be conditionally compiled, you may need to set the same macro when including the header file declaring Vpc3Read?
