Hi, 

I would like to change the spi clock of the flash interface . 

Can it be done via the Wiced or the OpenOCD?

 

Thanks

Hi,

This is not a straightforward and simple process. But, you can try changing the parameter NORMAL_READ_DIVIDER in platform_spi_flash.h file. Location:

43xxx_Wi-Fi\WICED\platform\MCU\BCM4390x\peripherals\platform_spi_flash.h

Thanks

Hi @LiGa_2316726 ,

Changing the frequency of sflash for CYW2070x devices needs to be done at firmware level. There is no way to change it in application.
