    Hi,
    External flash address range depends on size of sFlash connect tot the device. In the SBL it assumes 8MB and it is max it can support as per addressing mode.
    To the AWR device external flash address starts '#define SOC_XWR16XX_MSS_EXT_FLASH_BASE_ADDRESS 0xC0000000U'

    Refer SBL source code (sbl\sbl.h) which has address for MetaImage and Backup images. SBL: 0-512KB, MetaImage-APP: 512KB-1MB, BACK-Image: 1.5MB onwards.

    Regards,
