TMS320F2809: Static analysis errors in SYS/BIOS generated file

Thank you for this suggestion. I can technically alter this file but this is quite undesirable solution. I am basically changing a file that comes with XDC tools and will need to be changed (by anyone working on my project) on every update in his own installation.
Also I am not entirely clear on how to modify this correctly. "va_start" is not called anywhere in this file and I am not able to find where is this actually called from and what parameters are passed to this function. As far as I can see this gets assigned to "xdc_runtime_System_extendFxn__C" but I do not get any other references to that in my project.

I played with the Swi example a bit since I knew it called System_printf, and found that calls to va_start showed up in the generated .c file.

I'm a little surprised that you aren't seeing it in your generated file. Do you do System_printf (or similar function) calls in your project?

I am not using "System_printf" in my project. I found it in some unused library, but my problem persists even after removing that.

There are some calls to "va_start" in the "app_p28L.c" file but I am not able to find the connection between these and the "xdc_runtime_System_printfExtend__I" to prove that "va_start" is indeed called.
