Hi
I'm trying to get run the X-CUBE-SBSFU application. I'm working with IAR Embedded workbench. Like in the manual, I built all applications in the following order:
2_Images_SECoreBin
2_Images_SBSFU
2_Images_UserApp
I'm working on a Nucleo-G474RE Board. I disabled all security features for debugging.
Like I understand, I need to download first the 2_Images_SBSFU. If I do so and connect with the Tera Term I get the message:
= [SBOOT] Flash Configuration KO: Dual bank mode activated. STOP!
= [SBOOT] Security issue : execution stopped !
I can't find the reason for this issue.
So I tried to download the project "2_Images_UserApp" with IAR.
Then I am able to download a new Firmware with the Y-modem:

-- Image correctly downloaded - reboot
= [SBOOT] Flash Configuration KO: Dual bank mode activated. STOP!
= [SBOOT] Security issue : execution stopped !
But after the download the Error message above is popping up again. Also when I power cycle the board (unplug/plug USB cable) the same error message appears again.
Dos anybody has an idea what the reason might be for this issue? I'm trying since days to find a solution but can't build a working project. The idea is that after the firmware download it should be able to update a new firmware again of course.
Thanks a lot and hope anybody can help me, Dominik
