2.4.2 Software Components

This application showcases Diagnostic and Monitoring feature of mmWave sensor. It uses SafeTI Diagnostic Library (SDL) for diagnostic test implementation and mmWaveLink to configure monitoring on RF front end.

In this reference design application, few Diagnostic tests are done in secondary bootloader (SBL) at MSS core. At the end of these tests, SBL loads the main application to MSS & DSS RAM location reading MetaImage from sFlash.
