New ContributorCycloneV MPU clock frequency
Hello,
I am using the CycloneV 5CSXFC6C6U23I7 SoC. According to the specifications cyclone V, SX models should allow for a core frequency of up to 925 MHz.
However, when I try to change the Hard Processor Settings in the Platform designer I get the following error message:
"Error: hps_0: "MPU clock frequency" (desired_mpu_clk_mhz) 900.0 is out of range: 25.0-800.0"
Could someone tell me how I can avoid this, or in other words:
Could someone tell me how to set the MPU frequency of the 5CSXFC6C6U23I7 SoC to 900 MHz.
Many thanks in advance.
Andreas

Hi,
Have you changed the device assignment correctly in Quartus settings?
I didn't get the Quartus version that you are using, can you share the version that you are testing on?
aurec2Hi.
thanks for your answer. The device settings are correct, both in the platform designer and in quartus project. Normally I am using Quartus Prime 17.1.
The mentioned problem occurs in using Quartus Prime 17.1 and in Quartus Prime 19.1.
Best

Hi,
I recommend that you check the "MPU clock frequency" at the default value of 800 MHz. At boot-up, please re-check the clock frequency again.
