I am trying STM32CubeExpansion_SBSFU_V2.4.0 with 2 Active images and 2 Download areas and assigned the LOcation in mapping_fwimg.icf. Code is building but i am getting error = "[FWIMG] Header of SLOT_ACTIVE_2 is not under the firewall protection"

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.

Hi @DMira.1​ ,

while SBSFU 2-image code supports automatic configuration of up to 6 slots, you cannot have more than 3 slots of one kind automatically configured by the code. Please see the declarations in sfu_fwimg_regions.h

So while 3 active and 3 download works without any modification to the provided SBSFU, to actually get 4 slots of one kind you need to change the SBSFU code significantly. I believe it's possible to make it work in the end, but to be honest, I see no practical use for 4 active slots.

Kind regards,

J.

Hi @JHOUD​ 

Thank you for response, I tried automatic configuration but ends with some error. I modified in  sfu_fwimg_regions.h as well... Facing same issue

@DMira.1​ Can you be more specific?

I need a lot more detail to reproduce your problem. What "some error"?
