HPS Clock Frequency

Hello,

I'm wondering if the clock frequency of the HPS (@DE1-SoC, ARM Coretex A9) is reconfigurable.

That is, is there any way to change the clock frequency of the processor?

(As I know, it is fixed to 800MHz @DE1-SoC)

    Hi 서박사,

    1. Open the output clocks page of the HPS IP parameter editor in Qsys.
    2. Un-tick the use default MPU clock setting
    3. Manually set the MPU clock rate in the MPU Clock box
    4. Re-generate the Qsys system
    5. Re-compile the Quartus Prime project
    6. Generate a new Pre-loader using BSP-Editor

    Thanks.

    Regards,

    Aik Eu
