Increasing CPU clock frequency for BL653

[Ubaid_M]

Hi,

I am using nCS on nrf52833 based BL653dvk, I am based on default 32kHz CPU frequency.
I need to go higher up to 40MHz, kindly suggest what configuration options I can use to increase my CPU clock frequency up to 40MHz.

Thanks,

Ubaid

Hi,

The CPU clock speed of nRF52833 is fixed at 64 MHz, this is not configurable to higher of lower frequencies.

Best regards,
Jørgen

Hello Jørgen Holmefjord,

So I am to understand that CPU frequency cannot be changed for nRF52833..?

So what is achieved by changing:

CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC=32768

&

CONFIG_SYS_CLOCK_TICKS_PER_SEC=32768

..?
