Hi Fan, They both map to same physical flash hardware. But the reason why 0x8008 0000 is alos assigned in sysconfig is that, the boot control configuaration is stored in this address. In the example you could see that the boot_info is equated to __TI_SBL_FLASH_BOOTINFO_SECTOR_START . From this region, the boot region is determined. If you check the map file of the example you would see that __TI_SBL_FLASH_BOOTINFO_SECTOR_START is actually the 0x8008 0000 address. That is the reason why this region is kept assigned in sysconfig. The other flash region which ix 0x6000 0000 is assigned for application image load purposes.
