Hello I just migrated from STM32F407 to STM32F429, How DO I change the system clock from 168Mhz to 180Mhz. I modified the system_stm32f4xx.c file, but I cant change it. 

Please let me know.

Thanks

Read-Only ''can't change it'' or something else?

Copy a local version of the file into your project directory, and right-click and change the file properties/attributes.

Change the PLL settings, and SystemCoreClock, or copy a file from the STM32F429I-DISCO firmware. Also pay attention to the defines for the project, and the type of CPU
