hello world! is not displayed from Log_printf in CCS 5.3

Hatem

I am using CCS 5.3 on evm137

I run the example hello.c from DSPBIOS examples, but it seems I can not see "hello world!" printed anywhere from this line

LOG_printf(&trace, "hello world!\n");

I click Resume after the the entry point was reached.

But nothing appears

Hi, where are you looking for the LOG_printf statement? They should show up in tools->RTA->RAW Logs

Thanks for the reply.

I have looked at tools->RTA->RAW Logs as you can see from the attached image there is something else

You are looking at "All Log buffers". Please select just "trace" from the drop down located towards the upper right corner area.

Hi Judah,

Still no luck, I have attached two images before Resume and after Resume

Hi Judah,

After I Pause the execution, yes I can see the output of LOG_printf in the trace.

Is it possible to see the output while the program is still running?

It is possible but you would have to setup something called UIA.

The way you are setup right now you only get it when you halt the processor.

Hi Judah

Does the C6747/C6748 has contain UIA instrumentation?

DSP/BIOS does not support UIA. SYS/BIOS does.

DSP/BIOS supports stopmode (which you've used). To get the data off without halting the processor, you can try to use RTDX. However, TI no longer officially supports this interface.

Hello ToddMullanix,

I read this thread as I've exact the same Problem. I imported a CCS3.3 Project with Log_printf (and was able to see the output while the program is still running).

May I missed something but I did not catch the final end of the Story:

I use DSP/BIOS and I thought I use RTDX (May I miss a Switch to "more" turn on RTDX in CCS5 ?).

Now, is it possible to see the Log_printf "live" ? YES or NO ?

Thanks, Wolfgang
