LOG_printf - Nir Drang - Dec 7 15:47:00 2004

Hi, maybe someone can help me on this one. i call the LOG_printf every ~30ms . all works fine , after a while (could be even 1 hour) i can't see any more LOG_printf in the RTA Msg log panel. i placed a breakpoint in the IDL function and it is running. any explenation? Thanks, Nir. |

Hello Nir,
Your problem may not be this easy, but...
Are you set up for a circular buffer?? If your buffer is 'fixed', logging
will terminate when it is full.

Hi Mike,
yeah i do set up for circular.
when i halt the processor i can see the LOG_printfs that i couldn't see
in runtime.
again IDL loop is called.

Nir,
I am not sure what the problem is - if the data is in the buffer CCS
'should' read it. The info below may help to change the symptom or give a
clue.
You are calling LOG_printf every 30 secs - do you log a single entry at
this time?? [ie, If the log fails to update after an hour, there would
only be 120 entries logged]
Have you slowed down the host refresh rate??
Do some of the TI examples run and update continuously?? [like the volume4
tutorial]
Do you have any "stdio printf's" in your code?? [the answer should be
no]
Which c6x processor and version of CCS are you using??

Usually the LOG messages, as well as the CPU performance graph and
other RTDX stop showing when the DSP is close to 100% utilization. Check if the
CPU graph is still working or not when the problem appears.
