How to check CYW43907 processor clock rated ? How to set CYW43907 at 320MHz ?

[JeNg_3501476]

Is there any function to change the clock rate of CYW43907? What is the default clock rate ? To increase the performance of the chip how to set it to 320MHz?

Thanks.

The default clock rate is 320 MHz (PLATFORM_CPU_CLOCK_FREQUENCY) which you can check at 43xxx_Wi-Fi/WICED/platform/MCU/BCM4390x/platform_config_bsp_default.h. All the available clock frequencies for CYW43907 can be found at platform_tick.c which can be located at 43xxx_Wi-Fi/WICED/platform/MCU/BCM4390x/platform_tick.c. But I would not recommend going beyond 60-320 MHz range because we have seen some issues in the overclk and sub-50 MHz clock frequencies during our testing.
