SYS/Bios: How to use event levels in combination with Log_warning and Log_error?

Joachim Siegler

Hey TI-Community.

I am new to Sys/Bios and using it on a C674x DSP. At the moment I am trying to find out what is the best way to filter Log messages printed from my C++ code. I read about the Diags_User1 - Diags_User6 and the Diags_LEVEL1 - Diags_LEVEL4 in the RTSC Package Documentation. As mention in the documation the levels provide a easy way to filter out Log_print messages. Now I am looking for a similar functionality to filter Log_warning and Log_error messages by level.

Is there a way to pass a Diags level to this both macros?

Example for the use of Diags_USER and Diags_LEVEL:

Log_print0(Diags_USER2 | Diags_LEVEL1,"tsk0 Log_print0 Diags_USER2 | Diags_LEVEL1");

Joachim,
For errors and warnings, their levels are already defined in Diags, so you can't change their levels. But, you can filter errors and warnings if you configure the logger you are using for your C++ code. For filtering events first you need to use a logger that inherits IFilterLogger interface. Then, depending on whether you are setting up the filter mask at runtime or at the config time, you can use setFilterLevel or a logger's specific config time API for setting the filter level. You also need to set the flag ILogger.filterByLevel to true.
If you configure your logger to log only event at the LEVEL2 and higher, errors and warnings will not be logged. LEVEL3 will log errors, but not warnings, and LEVEL4 will log everything.
