Hi @vishnu_vr
If you are using S32DS, once SW32K3_FreeRTOS_DesignStudio_updatesite.zip has been successfully installed, you should be able to create an S32DS Project from Example. Refer to the image below for guidance.

If you download SW32K3_FreeRTOS.exe, a Demo folder is included in the installation package. If the default installation path is not modified, you can find it at: C:\NXP\SW32K3_FreeRTOS_11.1.0_7.0.0_CD1_D2510\Demo\CORTEX_M7_S32K3XX_GCC
