CCS/CCSTUDIO-C2000: Using SysStd in my .cfg file but still the only way to view System_printf output is to use System_flush()

Tool/software: Code Composer Studio

I am using SysStd in my .cfg but the only way I can see System_printf output in my Console is to do a System_flush() after every System_printf.

What else do I need to do so that I do not need to use System_flush()'s?

I tried to use the guidance here: http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/tirtos/2_16_01_14/exports/tirtos_full_2_16_01_14/docs/Users_Guide.pdf

Hi Dale,

The below thread has some good hints on getting this working:

Thanks

Thanks, that method worked.

Turns out I needed to add this include to my main.c:

#include <xdc/runtime/System.h>

I have had to revert to using CCS7 (7.0.0.00042) and the System_printf lines I added in my code when I was using CCS10 no longer show up in my console (even with a flush and a \r\n in them).

Any ideas why they would stop working in CCS7?

Are you using the same versions of TI-RTOS and other build tools (xdc, compiler, etc) with CCSv7?

Both use compiler TI v5.2.6, XDC 3.32.0.06_core and TI-RTOS for CC13XX and CC26XX 2.20.1.08.

The only difference I can see, which should not matter, is that CCS10 runs on a Win10 computer, while CCS7 runs on a Win7 computer.

Did you try running the same exact *.out file that worked in CCS 10 with CCS 7? Basically taking the *.out for CCS 10 and running it as is (without rebuilding)

I will give that a try but it will be a few days before I do, I will report back then... Thanks
