DFU OTA Single Bank

[JH7]

Hello.

I need to integrate the DFU OTA in my project (using nrf52840 + NCS 2.4.0) and I managed to make it work with MCUBoot in dual bank configuration, but, as I'll need the whole flash space, I can't really use dual bank. So, is there an example showing how to use MCUBoot or NSIB in a single bank configuration?

I found this old posts suggesting this is not possible:

But this feature was available in the old Soft Device. I hope there's still a way...

Thanks

Hi,

Unfortunately there exists no such samples. You need a secondary slot to store the image for OTA, either on internal or external flash 

Kind regards,
