Programing n51422

[Javier]

Good morning, i have windows 7 and at this moment i have installed "Gnu tools for ARM embedded Processors", "GnuWin32 ‐ GNU Make utility", "GnuWin32 ‐ Core Utility", "nrfgostudio + tool" and sdk 9.0.0.

I´m developing code using/modifying the examples and loading code by command line (USB) to nrf51:

make
nrfjprog --family nRF51 -e 
nrfjprog --family nRF51 --program (name).hex
nrfjprog --family nRF51 -r

This works but I have seen in "User Guide", that PCA10028 is an Interface MCU and i need to program directly n51422 without go through PCA10028.

Could someone help me saying how could i do this?

Thank you.

The nRF51 does not have USB, so you cannot program it over USB directly. You need some kind of external programmer for the initial programming. E.g. the onboard interface chip on the DK, or a SEGGER J-Link probe or something else. For later upgrades you can use DFU, if you have programmed the device with a bootloader.

Thank you for answer me, this is my nrf51.
