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

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!
