I had problem about flash memory

[jeidi]

Hello.

In STM32H7S7L8HXH_flash_default_app.ld, it is set to __FLASH_BEGIN = 0x08000000,
In STM32H7S7L8HXH_RAMxspi1_ROMxspi2_app.ld, it is set to __FLASH_BEGIN = 0x70000000.

In fact, 0x08000000 is not uploaded, and 0x70000000 is uploaded and works.

Can I find it in the parts related to the bootloader in the Datasheet?

Thanks
