TMS320F28027: call a function from another project

Hi Howard,

Have you inspected the .map files of the two projects to make sure there aren't any conflicts in where both projects are placing code/data? When you step through the code, are the global variables being read from the expected locations? Are the global variables the only reason why the funcB() and funcC() don't execute correctly or do they appear to be executing totally incorrect code?

Hi, I've inspected that there is no conflict for these two projects.

1. funcB() is dealing with global array, and funcC() is dealing with struct, for funcA() dealing with variable, there is no problem

2. I cannot step through the function because the function is in another project. For example, I'm calling funcB() and funcC() in app project, but funcB() and funcC() are in boot project.

Thanks.

Looking forward to your answer.

Howard,

I think I need more details. What goes wrong with function B and C? Do they at least return properly? Is it just the variable values are wrong?

I know you can't exactly step through the C code, but judging by the disassembly window, do you have a sense that the call to these functions is taking you to the correct location?

Whitney

Thanks, I'll take some actions and reply to you soon.
