$ git clone git@github.com:interoberlin/blessed.git
$ cd blessed/
$ make PLATFORM=nrf51822 NRF51_SDK_PATH=../NordicSemiconductor/SDK/
make: *** No rule to make target 'build/system_nrf51.o', needed by 'build/libblessed.a'.  Stop.

Reason: system_nrf51.c is not found and therefore not built, although needed. It's probably a problem with the NRF51_SDK_PATH.

Solution: Download the SDK or MDK from Nordic Semiconductor and copy the following files over:

core_cm0.h
core_cmInstr.h
core_cmFunc.h
nrf.h
nrf51.h
nrf51_bitfields.h
nrf51_deprecated.h
system_nrf51.c
system_nrf51.h
compiler_abstraction.h
gcc_startup_nrf51.s
