* - Set the FreeRTOSDemo_s project as Active - Right click on | |
* "Project: FreeRTOSDemo_s" and select "Set as Active Project". | |
* - Build the FreeRTOSDemo_s project using "Project --> Build" or by pressing | |
* "F7". | |
* - Set the FreeRTOSDemo_ns project as Active - Right click on | |
* "Project: FreeRTOSDemo_ns" and select "Set as Active Project". | |
* - Build the FreeRTOSDemo_ns project using "Project --> Build" or by | |
* pressing "F7". | |
* - Start Debug Session using "Debug -> Start/Stop Debug Session" or by | |
* pressing "Ctrl+F5". | |
