STM32H743I_EVAL Board: Why do we config MPU ?

Hi ,

I am seeing

STM32Cube/Repository/STM32Cube_FW_H7_V1.1.0STM32H743I_EVAL/Applications/LwIP/LwIP_TFTP_Server/Src/main.c

and found that MPU_Config( ) is initialized where base address=0x30040000 and MPU region size is 256B.

__My queries are :

1) Why do they select base address as 0x30040000 ?
2) What is the reason of choosing MPU region size as 256B ?
3) In STM32H743XIHx_FLASH.ld, i found :

Memory_B1(xrw) : ORIGIN = 0x30040000, LENGTH = 0x60
Memory_B2(xrw) : ORIGIN = 0x30040060, LENGTH = 0x19F
Memory_B3(xrw) : ORIGIN = 0x30040200, LENGTH = 0x2000

What does above mapping signify ?__

Manish
