How to increase freq of MCU to 480MHz?

How do I raise the MCU frequency to 480MHz?

Can I just change

    void Defaults()
        cpu_freq   = SysClkFreq::FREQ_400MHZ;
        use_dcache = true;
        use_icache = true;

to FREQ_480MHZ in


and it will work?

I am curious what these extra 80/400 % clock cycles will mean for my code (specifically, more running oscillators)! :slight_smile:

Will that introduce any problems with DaisySP and/or libdaisy, timing issues etc?

There’s no need to edit libdaisy sources. The proper way to use it is by setting boost = true when you init the board in your patch:

Yup, 20% more oscillators at your service. I’m not aware of anyone running into problems from running it on 480Mhz, but that would obviously increase power dissipation to some extent.

Thank you for your quick answer, @antisvin! (Somehow I knew that you would be the first to anwer this. :slight_smile: )

Seems very simple, I’ll try it right away! :+1:
