1. Power up the BoSLcam using a battery.
2. Plug the Segger J-link into the computer.
3. For the modem firmare, follow the instructions at: https://www.bosl.com.au/wiki/NRF9160_modem_firmware to flash modem firmware version 1.3.2 available at: https://www.nordicsemi.com/Products/nRF9160/Download#infotabs
4. For the application firmware, open the J-Flash or J-Flash Lite tool if programming for development purposes ([1]). We will tailor instructions for the J-flash lite tool.

6. Under the Data File open the firmware "BoSLcam_firmware_revx.x.x.hex" file.
7. Connect the pins on the "SWD" header to the associated pins on the J-link probe. A pinout for the J-link for SWD can be found in its instruction manual [2]. The depicted programmer probe may also be found useful for breaking out the small header pins.
