I'm using STM32H7R7, and I want to configure clock with 24MHz HSE(CPUCLK@600MHz), but the CubeMX can't resolve the error automatically. What should I do?

 

Thanks!

CPU clock looks like it's at 600 MHz to me.

Adjust PLL2 to get the speeds you want on PLL2S and PLL2T. Same with PLL3. Hovering the error will tell you what's wrong. Probably need higher clock rate where it's red.

Set the PLLs to a clock in their range.
