Hi @DMira.1​ ,

I raised your issue internally, and still waiting for response from the specific team.

Best Regards,

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"?
