Newbie question: Clock configuration in SYS/BIOS

Other Parts Discussed in Thread: SYSBIOS

Hi,

I have played around with a Concerto controllerCard and have transformed a simple blinking led example into a SYSBIOS project which now controls the blinking.

I was able to get it blinking without setting the main clock, I guess the clock is defined inside the SYSBIOS, but where do I find the configuration data?
Is it possible to configure the peripherals clocks through SYSBIOS also, or do I have to set this in the code?  

  • Jorgen,

    You can configure the PLL and the device clock dividers in the M3-side Boot module’s configuration.  If you open the M3-side application .cfg file in the XGCONF graphical tool, then click on “System Overview”, and the “Boot” box within the Startup group, you’ll see a configuration screen like that below.  Check the box at the top “Add Concerto M3 Boot management to my configuration”, and then you can edit the PLL and clock divider settings, then save and rebuild the application.



    To change any peripheral-specific clock settings or dividers you’ll need to do that in your application code.

    If you want to change the settings of the SYS/BIOS Clock module (that defines the SYS/BIOS tick rate), go back in the “System Overview” page, and click on the “Clock” box within the Threads group.  



    If you want to change the tick rate, change the value in the “Tick period” box in the lower left.
