While using DFU and with respect to this: infocenter.nordicsemi.com/index.jsp nRF51:

the softdevice no longer starts at 0x0 right, but at 0x1000?
Or it starts at 0x0 since the MBR is part of the Softdevice?
And the application starts at 0x0001 B000?

Thanks!

To erase the chip you have to enable erase and erase using the NVMC. It is documented here: infocenter.nordicsemi.com/.../Chunk208541660.html

That would be:

w4 4001e504 2  #CONFIG register, enable erase
w4 4001e50c 1  #ERASEALL register

To flash the softdevice you can write:

loadbin $SOFTDEVICE 0x0  #flash in address location 0

To flash the application you can write:

loadbin $APPLICATION 0x1f000  #flash in address location 0x1f000  (s132_nrf52_1.0.0-2.alpha version)

A script to erase, flash SD, flash application and reset would look something like this:

device nrf52
speed 1000
w4 4001e504 2
w4 4001e50c 1
sleep 100
r
loadbin $SOFTDEVICE 0x0
loadbin $APPLICATION 0x1f000
sleep 100
r
g
exit

Not a complete answer for you, but a tip: The new development kits will show up as a block device/flash drive when connected. It is possible to copy a file to this folder, and it will automatically be flashed and the device reset. Is this something you could use? This would need you to merge the hex files in advance though.
