bios6 hw timer usage

Other Parts Discussed in Thread: SYSBIOS

Hi,

On the 8148, there are 8 timers.   I have created a driver for the timers, but don't want to conflict with Bios usage.   In the Clock section I see that it is set to 'timerId = 1'.  Does this mean that it uses GPtimer1?  In general is there a mapping from bios to gptimer?   I remember that Bios5 was more explicit here?

Thanks,
Matt

    The timer mapping is not 1-to-1.   The mapping can be found in the timer mapping tables:

    You can get to the API documentation (cdoc) via Eclipse help system.    Or via a link in the release notes. 

    Navigate to this module

    ti.sysbios.timers.dmtimer.Timer

    And click on the timer mapping link.   There's a separate mapping for each core.   On the DSP side, BIOS uses logical timer 0 (timer3) by default.
