Change the CPU frequency of HAN Pilot Platform - Change the CPU frequency of HAN Pilot Platform Hello. I've changed the cpu frequency of arria 10 using intel quartus design platform. (I changed mpu_base_clk: 0.9v, 1.0 GHz -> 0.95v, 1.2 GHz) When i type command cat /sys/kernel/debug/bpmp/debug/clk/clk_tree after compilation, clock value is not changed. How can I apply the newly changed clock? thanks. Replies: Re: Change the CPU frequency of HAN Pilot Platform You have to regenerate your system in Platform Designer.
