Why can't use L1 cache on cube mx, Memory manage also can't use L1 cache

Why can’t my cubemx configure L1 cache? How to enable it?

Also, the MPU cannot be configured. You can only use the default configuration and modify it in the generate code.

I also configured Memory management, but did not see the enable Cache and MPU synchronization settings

CubeMx 6.16.1 on macos

MAC 26.1

MCU:STM32H743IIT6

Hello @luke gong

You need to make sure that the option "Apply Application Region Settings to Peripherals" is OFF

Then go back to your MPU configuration: you will be able to enable the CPU I‑Cache and D‑Cache (L1 cache) and modify the settings as needed.
