Flashing softdevice with the latest nrfjprog

[Tim]

I haven't updated my copies of the nRF tools, or mBed's nRF51 code for some time. I just did and now it seems my old method of flashing no longer works. I was doing something like:

nrfjprog --erase-all --programs s130_..._.hex --program my_firmware.hex --dfu

Now there is no --programs, or --dfu. And also I noticed there is are some bootloader hex files in the source tree.

1. What are the bootloader hex files? Do I need them? Why didn't I need them before?
2. How can I program the softdevice and my app firmware in one command as before?

This works:

nrfjprog --family NRF51 --program my_firmware.hex --chiperase

But it doesn't put the softdevice on there...

In general, you can program the device using nrfjprog version 7.6.0 in the following way.

Erase all, program SoftDevice and verify:

nrfjprog.exe --family NRF51 --program s130_softdevice.hex --chiperase --verify

Program application and verify (use --sectorerase in addition to erase old application before programming):

nrfjprog.exe --family NRF51 --program nrf51422_xxac_s130.hex --verify

Apply reset in order to start the application.

nrfjprog.exe --family NRF51 --reset

You only need the Bootloader if you use DFU.
