BLE DFU single bank support for bootloader+softdevice update

[westhouse]

"BLE DFU single bank support for bootloader+softdevice update". I found it in change log of SDK 7.1.0. What does it mean?

@WrightCS: As Alex said, the difference is only on the bootloader, not on the DFU master. The DFU master sees the DFU process the same with single bank and dual bank. However, you have to make sure the DFU master waits long enough for the bootloader on the nRF51 to erase the whole swap area (region 1). Our phone app should supports single bank application update already, you don't have to modify it.

The message ""Old DFU only supports Application upload" telling that you haven't selected the init packet. Which SDK version did you use ? how did you create the init data packet ?

Is there any Single Bank Bootloader for sdk7.1 and nrf51822_xxAB witch I can compile on first attempt without any changes of something ?
