SBSFU 2.6.2 firmware swapping issue
Hi Guys,
Ported SBSFU 2.6.2 to STM32G0B1CEU6 (512K FLASH and 64K RAM) based on Nucleo-G071RB example.
Modified mapping_fwimg.ld as below:
/* Slots must be aligned on 2048 bytes (0x800) */
/* swap (4 kbytes) */
__ICFEDIT_SWAP_start__ = 0x08042000;
__ICFEDIT_SWAP_end__ = 0x08042FFF;
/* Active slot #1 (200 kbytes) */
__ICFEDIT_SLOT_Active_1_start__ = 0x08010000;
__ICFEDIT_SLOT_Active_1_end__ = 0x08041FFF;
__ICFEDIT_SLOT_Active_1_header__ = __ICFEDIT_SLOT_Active_1_start__;
/* Dwl slot #1 (200 kbytes) */
__ICFEDIT_SLOT_Dwl_1_start__ = 0x08043000;
__ICFEDIT_SLOT_Dwl_1_end__ = 0x08074FFF;
/* Slots not configured */
__ICFEDIT_SLOT_Active_2_header__ = 0x00000000;
__ICFEDIT_SLOT_Active_2_start__ = 0x00000000;
__ICFEDIT_SLOT_Active_2_end__ = 0x00000000;
__ICFEDIT_SLOT_Active_3_header__ = 0x00000000;
__ICFEDIT_SLOT_Active_3_start__ = 0x00000000;
__ICFEDIT_SLOT_Active_3_end__ = 0x00000000;
__ICFEDIT_SLOT_Dwl_2_start__ = 0x00000000;
__ICFEDIT_SLOT_Dwl_2_end__ = 0x00000000;
__ICFEDIT_SLOT_Dwl_3_start__ = 0x00000000;
__ICFEDIT_SLOT_Dwl_3_end__ = 0x00000000;
Following the step-by-step guide in UM2262.

Any idea why this issue is happening? Thanks.
