Hi @DMira.1​ ,

Sorry for the delay, we were celebrating Aid.

Can you specify which project exactly did you run.

Best Regards,

Ons.

There is only one project on L476RG in​ STM32CubeExpansion_SBSFU. It is working with out any issue. But I added 2 active and 2 download slots by modifying Macros SFU_NB_MAX_ACTIVE_IMAGE and SFU_NB_MAX_DWL_AREA. And even i added memory locations in mapping_fwimg.icf. Please refer the image attached. I am getting error SLOT_ACTIVE_2 is not under firewall protection.
