Running SYS/BIOS Clock Example on TMS320C6748

Other Parts Discussed in Thread: TMS320C6748

Hello I'm tring to run the clock example on my TMS320C6748 DSP.

(Code Composer Studio  Version: 5.3.0.00090 , sys/bios 6.34.2.18)

When I run the code which creates 2 clock functions, non of which is reached, I can see the clock ticks are not increasing (in ROV view)

I also can the see the clocks are created, enabled and started (in ROV view)

What else should be configured for the clock to start working ?Do I need to configure the Timer module ? Do I need to Init the Power Module somehow ?

I'm not interested in using .gel files, what kind of initializations I need to do? 

 

Thank you In advance

Alla

    Hi Alla,

    What is going on in the system? Can you look at Hwi, Swi and Task in ROV? By default SYS/BIOS sets up a timer to drive the Clock. Did you change any of the default Timer or Clock configuration (might be easiest to attach your .cfg file). Also, could you have a high priority interrupt that is starving the system?
