3.1 File to Download

One or more of the following binaries comprises of the files to be downloaded:

  • RadarSS Image (Complete firmware (pre-production) Or Patch if any (production devices))
  • MasterSS Image (Functional firmware (pre-production) Or Patch if any (production devices))

In AWR2243 ES3.0 (production variant), these two images are combined into a single MetaImage file which must be flashed to the device.

TI’s DeviceFirmwarePackage (DFP) for XWR12xx would include the necessary files to be downloaded to both the MasterSS as well as RadarSS.

TI’s mmWaveSDK package for XWR14xx would include the “Image Creator” utility that would help constructing the complete image with the above listed components for use with XWR14xx devices.
