I'm unable to set the clock frequency above 650Mhz, but according to the datasheet, the mpu i selected should be able to reach 1000mhz. What am I doing wrong?Screenshot (9).png

Hello

I just tried to define a new project using STM32MP135FAFx with CubeMx (v6.12.0) (latest on st.com web is 6.12.1)

I do not see the max 650 Mhz ?

Maybe you are using an old version of cubeMx ?

How did you create your project ?

I simply select STM32MP135FAF7 in the MCU selector, then "create new project", then enable HSE and set it to 16 Mhz in the Clock configuration sheet. Then updated a bit the various settings of PLL to match your screen shot.

I always could see max 900 Mhz in the MPUSS_CK

Hi,

I'm having the same problem as the original poster when trying to set up a bare metal project for the STM32MP135F-DK or just STM32MP135FAFx. Using the latest CubeIDE or CubeMX. The HSE is 24Mhz on the board, so that is what it is set to.

 

I presume there must be some other setting to enable this to go up to 1000MHz? But I can't see what that would be.
