cloning this repo you need to run the following command:
git submodule update --init
## Option 1: Build with makefile
Navigate to `src/singlebank` (recommended) or `src/dualbank` (work in progress), and use feather52840 target for building bootloader.

For better debugging you can also use SES, The project file is located at `src/segger/nrf52840_bootloader.emProject`. Note: the SES only flash the bootloader when you click download, you need to flash Softdevice beforehand if you haven't done so ( use `make flash_sd` mentioned above )
