Just a quick update. With SDK 12.3 I got blinky running.
Edit: So far I only got the precompiled blinky_pca10028.hex working. If I compile it myself I get an nrf51422_xxac.hex in nRF5_SDK_12.3.0_d7731ad/examples/peripheral/blinky/pca10028/blank/armgcc/_build, but it won't run after flashing.

Update: I got it working with help of this blog post https://hackaday.io/project/28180-bluetooth-gamepad-phone-case/log/71821-nrf5-sdk-setup-compilingrunning-sample-applications

I just had to change the target in the Makefile and flash RAM start and size.

Another Update: I got the s130 version working to by following this guide https://devzone.nordicsemi.com/b/blog/posts/rom-and-ram-management and realizing I need to flash the soft device, too.

So for everyone new like me: You need to flash the softdevice from $(SDK_ROOT)/components/softdevice/s130/hex/s130_nrf51_2.0.1_softdevice.hex and then flash the example project with FLASH and ROM settings in the blinky_gcc_nrf51.ld modified according to the guide above!

I see. So does this mean there is no more support for nRF51 chips or is SDK 12 still activevly developed? Also are there major differences in the SDK APIs? Ideally I would be able to write the same code for nRF51/52 for most of my applications, but this seems not possible then...

The latest SDK for NRF51x has 12.3 version number. You need to download this SDK instead of 15.x.
