What is the proper way to upload S110 and bootloader in PCA20006 beacon?

[Johnson]

First of all, I managed to successfully upload S110 and dfu bootloader (from SDK 9.0.0) individually to nRF51-DK board via OTA DFU using the Master Control Panel app. Initially, I uploaded both S110 and bootloader using the cable. Then I re-uploaded them via OTA DFU.

However, when I tried to upload the same S110 to the beacon board, it "broke" the bootloader. Here are my steps:

1. Generated the zip file for S110 by running nrfutil.exe on S110_softdevice.hex. The hex file was from C:\Keil_v5\ARM\Pack\NordicSemiconductor\nRF_SoftDevice_S110\8.0.2\hex.
2. In the Master Control Panel app, I did DFU and selected the zip file.
3. After the S110 upload finished, I power-cycled the board while holding SW1 but it did not seem to enter the bootloader mode. Master Control Panel could not detect the device advertising as DfuTarg and the LED was constantly purple.

I thought the original DFU bootloader would still work after updating the new S110. Does this mean I now need to use the adaptor cable and the nRF51-DK board to upload the DFU bootloader?

Edit:

Assuming that the S110 upload is working, when building the dfu bootloader project in Keil, I should change the device type from nRF51422 to nRF51822, shouldn't I? Though, according to this thread, it did not matter? How about the comment that the internal ANT hardware is disabled by default?

Hi Johnson

If the Beacon kit onboard bootloader is corrupted already, the only way is to connect a programmer to the Beacon kit and program the bootloader and perhaps softdevice again. You can connect Beacon kit and programmer/nRF51DK with an adapter cable or soldering, as described on this thread.

The nRF51822 and nRF51422 is basically the same chip, see this thread.
