nRF51 s110 softdevice is used by default (see Makefile.project), so at first you need to flash the softdevice binary:
make softdevice
The above command erase the chip and programs the softdevice binary appropriately. Now compile the user program and flash/upload it:
make
make upload
Use segger.py script directly to flash .bin binaries.
export BUILD_PATH=./build
export JLINK_PATH=/usr/bin
python segger.py flash examples/ble_peripheral_proximity_nrf518222_xxaa_s110.bin 0x18000
