Hello,
I have update a CubeMX project from V6.6.1 to V6.7.0.
After update, without any changes, the clock configuration has a lot of errors. The CPU has a maximum clock rate from 480MHz, but the new CubeMX V6.7.0 allow only 200MHz!?!
The Error:
"D1CPRE Clock frequency must by <= 200MHz"
Attachment: The Clock configuration and a lot of red fields.
Please fix this problem and help me what is going wrong. Thank you very much.
Solved! Go to Solution.

Hello @Markus Müller ,
A similar question is already asked here.
To get 480 MHz, go to the RCC parameters and check that the product revision is "V".
For some reason the default is "Y".
Then set the power regulator voltage scale to 0.
I reported this issue internally.

Yes, it works, Thank you very much for the fast answer.

The error was:
"D1CPRE Clock frequency must by <= 200MHz"
can you change the hint texte to:
"D1CPRE Clock frequency must by <= 200MHz, please change the RCC parameter and check that the product revision is "V""
Thank you very much.

@KDJEM.1 - I have similar issue - using STM32H743ZI with STM32CubeMX 6.9.1.
I did what you suggested but still no change in the clock configuration
see:
also my RCC configuration:
I didn't had this issue in older version of STM32CubeMX
pls help :(
thanks

Hello @Mz.1 ,
I think that this question has already been answered here CubeMX 6.9.1/ STM32H743ZI / Clock Configuration is... - STMicroelectronics Community .
Could you please confirm this?
Thank you.

Regarding CLK, it can be executed normally, but why is an error displayed?

Hello @garry lai and welcome to the Community :),
Could you please give more details about your issue?
Which MCU are you using ? Which MCU revision are you using?
Are you using STM32CubeMX6.9.1 version?
Thank you.
