HPS Clock Frequency

[서박사]

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.

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!
