How to flash bootloader with JLink / gcc ?

[Thomas]

Hi ; Following my question how-to-flash-with-jlink-command-line which was successful, I can flash Soft Device and my app on my nRF51822 board (mac os x + gcc)

Now I would like to flash the bootloader

if SWD
speed 4000
device nrf51
w4 4001e504 2
w4 4001e50c 1
sleep 100
r
# OK - this works for SD + app only / no bootloader
loadfile s110_nrf51822_7.0.0_softdevice.hex
loadfile app.hex

# FAIL - this does not work for bootloader + SD + app
loadfile bootloader_dgs_V0_AA.hex
loadfile s110_nrf51822_7.0.0_softdevice.hex
loadfile app.hex

sleep 100
r
g
exit

Any help ? Thanks

@Tanasis: Please create a new question with more detailed description, please try to flash the softdevice before the bootloader and flash only the softdevice and bootloader (no app) first, for testing.
