How to enable MAIN clock and AUDIO PLL clock at same time

zenghuchen — Thu, 15 Feb 2024 17:55:25 GMT

I attached audio pll clock to ctimer0 (CLOCK_AttachClk(kAUDIO_PLL_to_CTIMER0)), but read an offset between ctimer0 and system clock. Output of ctimer0 is around 100 ms later than system clock.

If I attach main clock to ctimer0 (CLOCK_AttachClk(kMAIN_CLK_to_CTIMER0)), I read the same value from ctimer0 and system clock.

And because of the system design, I must use audio pll clock.

So is there a way to enable main clock and audio pll clock at the same time?

Or any other way to read similar value?

Thanks.
