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,
- Open the output clocks page of the HPS IP parameter editor in Qsys.
- Un-tick the use default MPU clock setting
- Manually set the MPU clock rate in the MPU Clock box
- Re-generate the Qsys system
- Re-compile the Quartus Prime project
- Generate a new Pre-loader using BSP-Editor
Thanks.
Regards,
Aik Eu

Thank you for your effort and time for the solution!
