Updating the firmware

  3. Select the kit you want to update the firmware of.
  4. Open the Kit Manager
  5. If your kit hasn't yet been updated, and you have the latest version of Simplicity Studio, a dialog box should appear telling you that a new firmware version is available to install. Click 'yes' to install the new firmware.
