maximum application size and still support dual bank DFU?

[Allen]

Hello,

We are upgrading a nrf52832 project which is based on SDK 14, soft device 5. Currently we depend on dual bank DFU operation but our application. Unfortunately we are running out of space for our application.

Is the maximum allowed application size to support dual bank DFU functional, per SDK/Soft Device, documented anywhere?

Thanks

Hi Allen, 

Please see the Dual-bank and single-bank updates documentation.

Hello Amanda,

I am familiar with this information. It describes the dual bank DFU operation but it does not document the maximum application size for a particular soft device and SDK. 

Where can I find the maximum application for dual bank DFU operation for the nRF52832 processor soft device and SDK version?

Thanks
