How to Flash a Silicon Labs Device

Once you have an image built, you can flash it onto your EFR or SiWx917 SOC device (either a development board or the Thunderboard Sense 2) over USB connected to your development machine. This can be done using either Simplicity Studio or Ozone J-Link Debugger or the standalone Simplicity Commander.
