• Navigate to demo/dfu_sim3 directory and execute:

Alternately, on Windows, the "build_flash_dfu.cmd" or "build_flash_dfu_101.cmd" (for 1.0.1 toolchain) within the demo/dfu_sim3 directory.

This requires the Si32FlashUtility (extract the linked flash utility to C:\Si32FlashUtility, so that Si32FlashUtility.exe is at C:\Si32FlashUtility\Si32FlashUtility.exe). This tool will generally flash the part more quickly than the alternative approach.

Note that this requires that the linker of any images to be loaded be set to have a 0x3000 offset. Building without this modification will result in boot failures where the entry points in the image will cause jumps into the bootloader rather than the image.
