You can try using single bank bootloader, as i mentioned before.

As i already answwered in your different topic, you are using nrf51822 with only 128kb rom and 16kb ram, and it is revision 2 chip. you should switch to revision 3 chip to use SDK10 and newest softdevice. But for development purpose you could try compiling single bank bootloader or modify dual bank to fit in your memory layout.
