Regarding the title, please show me the initialization code. I have a NUCLEO-H723 and a Discovery H735G-DK. Thank you.

STM32 is an MCU, not MPU.

L1 cache is internal to CPU core and is not accessible by DMA or any other peripheral. Also it cannot be operated directly by addresses even by user code. Read the AN4839 and AN4891.

Thank you. Is there an indirect method?
