BLE Secure DFU Bootloader Single Bank Operation

[jmp246]

I am currently using BLE Secure DFU Bootloader on my NRF51822 256kB but my program is now too large for dual bank operation. How can I setup the Secure DFU Bootloader to use a single bank?

As shown by the bootloader printing out the below. 0> :INFO:No way to fit the new firmware on device

My program is 66kB in size.

I'm using SDK 12.2.0 and S130 2.0.1. Turns out my program was actually. 143812 bytes and I only had 107520 of free space. So I had a look at the map file to see what was using the flash. Now it works fine.
