RTOS/EVMK2H: How do I set sys clk in TI-RTOS?

Tool/software: TI-RTOS

Hi.

I use K2H board.  I reconfigure DSP sys clock. I set DSP input clock. and I check 1S counter, but 1S is not a 1S.

I think, If DSP clock were changed, TI-RTOS setting is change too. but I can't find TI-RTOS clk setting.

Should I know how to configure clock setting in TI-RTOS.

Regards.

Shin.
