    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

    Thanks.

        Sorry for the late response.

        I'll try to change the clock frequency through the method you suggested.

        Thank you for your effort and time for the solution!
