nucleo-f429zi usb configuration

[yang hong]

I am using nucleo-f429zi with stm32cubemx. I found the default system clock in stm32cubemx is 168MHz for nucleo-f429zi. when I add usb fs in my application, I can't change to system clock 180MHz because pll_q can't get 48MHz. anybody knows how to configure my usb application with 180MHz in stm32cubemx?

any st engineer can reply my question? I would like to configure system clock to 180MHz in nucleo-f429zi using stm32cubemx, but it looks usb need 48MHz. It seems I only can set 168MHz for system clock. is it right?
